Determining patterns in loading the body of a gondola with side wall cladding made from corrugated sheets under operating modes

The object of research is the processes of emergence, perception, and redistribution of loads in the body of a universal railroad gondola with a cladding of corrugated sheets. To improve the strength of the sheets of cladding, it is proposed to strengthen the most loaded area in terms of height (1/3 of the bottom tie-up) with horizontal corrugations. Determination of the geometric parameters of the corrugation is carried out by the moment of resistance of the sheet. The dynamic load of the gondola body with improved cladding was determined by mathematical modeling. The fluctuations of the jump were taken into consideration, that is, the translational movements of the body relative to the vertical axis. The results of the solution of the mathematical model have made it possible to conclude that the studied dynamics indicators are within the permissible limits while the car movement is estimated as "excellent". The calculation was performed of the strength of the body of a gondola with improved cladding. It has been established that the strength of the gondola body under the main operating load modes is ensured. According to the results of calculations of static strength, the calculation was performed of the fatigue strength of the gondola body. It must be said that the fatigue strength of the body cladding increases by 3.7 % compared to the typical one. A feature of the results obtained is that the proposed improvement of the cladding can be carried out not only at the design stage but also during repairs of cars. The scope of practical use of the results includes the engineering industry, in particular railroad transportation. At the same time, the conditions for the practical application of the research results are compliance with the requirements for loading and unloading operations of gondola cars. The results of the current research will contribute to devising recommendations for the design of modern structures of gondolas and for improving the efficiency of their operation.

A multifield loads evaluation method for offshore wind turbines considering multivariate coherence effect

The structural design and reliability assessment of offshore wind turbine systems for maximally exploring the renewable energy resources significantly rely on the actual marine environmental loads. The major challenges arising from the estimation of offshore wind turbine loads are the effects of rotating blades on wind velocity and the interactions among multiple components such as wind, waves and the structure. These factors make the environmental loads more complex and multivariately correlated. To address such issues, a multivariate coherence effect (MCE)-based evaluation method has been proposed to analyze the rotational effect on the wind velocity by discovering the perturbation mechanism of wind spectrum. Furthermore, analytical formulations in the form of the blade speed and wind spectrum have been developed to construct the MCE-based joint power spectrum matrix for the load redistribution via intercorrelations among multiple domains representing the ambient environment of offshore wind turbines. Results show that the MCE-based method has the ability to retain the characteristic multiple rotational frequencies of rotational blades and enables the simultaneous reconstructions of the stationary-state wind field, rotational wind field and wave height sequences for accurate load redistributions by decomposing the MCE-based joint power spectrum matrix. As compared with the traditional techniques, a more cost-effective approach can be further developed for the reliable estimation of the blade flapwise deflection using the proposed method. Summarily, the present work provides analytical formations for the accurate load configuration and dynamic analysis of offshore wind turbines subject to harsh marine environments.

Numerical Assessment on Continuous Reinforced Normal-Strength Concrete and High-Strength Concrete Beams

High-strength concrete (HSC) has been broadly applied to various civil structures for its advantages including high compressive strength and excellent durability and creep resistance. However, the brittleness of HSC raises concern about its use in practice. So far study on continuous reinforced HSC beams is limited. This work investigates the structural response of reinforced HSC continuous beams, and the results are compared with those of the counterparts made of normal-strength concrete (NSC). By applying a finite element method verified by experimental data, a comprehensive assessment is performed on two-span reinforced NSC and HSC (compressive strengths of 30, 60 and 90 MPa) continuous beams. A wide range of flexural reinforcement ratios are used to cover both under-reinforced and over-reinforced beams. The results show that reinforced HSC beams exhibit better flexural performance in terms of ultimate load, deformation, flexural ductility and moment redistribution, when compared to reinforced NSC beams. Formulae relating flexural ductility and moment redistribution with either neutral axis depth or tensile steel strain are suggested.

A novel tier-based numerical analysis procedure for the structural assessment of masonry quay walls under traffic loads

Historical quay walls constructed in unreinforced masonry are integral elements of many cities. Originally designed as gravity retaining walls, they are nowadays often subjected to the action of traffic loads as a result of vehicles travelling on roads constructed on their backfill. This paper presents a numerical analysis procedure for carrying out the structural assessment of quay walls under traffic loads. The procedure simulates the non-linear dynamic response of the quay wall under the effect of the passage of a vehicle. Non-linear dynamic calculations are performed not only to be representative of the actual nature of loading but also to produce realistic estimations of structural safety, load redistribution capacities and displacements. Adopting a tier-based approach, the computational burden typically associated with such simulations is significantly reduced. This is obtained by adopting simplifications which allow for the modelling the 3D soil block comprising the backfill of the quay wall only in the first tier of the procedure. To demonstrate the implementation of the procedure, a detailed application to an existing quay wall in Amsterdam, the Netherlands, is presented. Different foundation damage scenarios are also considered. Though the procedure is presented in this paper for a specific typology of quay walls, it has conceptual and methodological value. With appropriate modifications it can be used for the structural assessment of other earth retaining structures as well, under the effect of vehicular traffic on their backfills.

Spatial variability of explosive blast loading and its effect on damage risks to reinforced concrete buildings

Explosive blast loading is subject to inherent variabilities due to complex interactions between chemical reactions, air particles, fireball and shockwave. Explosive field trials have quantified this variability, and described herein is the probabilistic characterisation of spatial variability of airblast for pressure and impulse. In other words, pressure–time measurements from adjacent (close) gauges are not identical, but correlated based on the distance between adjacent gauges. The degree of correlation is moderate if distance between adjacent gauges is small (i.e., angle between gauges is small where each gauge has the same radial standoff from the charge), and reduces to a weak correlation for gauges spaced much further apart. The effect of spatial variability of airblast on damage and collapse risks is investigated for a 10 storey reinforced concrete building subject to a vehicle borne improvised explosive device (VBIED) attack, and the accidental detonation of explosive ordnance (EO). The structural reliability analysis considered load redistribution for failed columns, dead and live loading variabilities, and blast loading and resistance model errors. It was found that allowing for the spatial variability of airblast decreased progressive collapse probabilities by up to 65% when compared to the case of fully correlated airblast. Designing against progressive collapse using either a threat dependent design or the Alternate Path method reduced damage risks by over 90%, and in many cases by over 99%.

Preloading of four-legged jack-ups in clay: Geotechnical time effects and fulfilment of preloading criteria

Presented here is a numerical study on the preloading of four-legged jack-ups, such as those commonly employed in the construction of offshore wind farms. The need for reducing jack-up installation time is particularly felt within the offshore industry, especially when multiple preloading cycles are necessary in clayey soils to fulfil given preloading criteria. This is due to clays experiencing delayed deformations, causing load redistribution among all legs while the ideal situation of steady preload on all spudcans is pursued. This work employs three-dimensional finite element (3D FE) modelling to analyse the preloading performance of a reference jack-up vessel in clayey soils using a wished-in-place (WIP) approach. Detailed modelling of time effects due to soil consolidation and viscosity is introduced, with some emphasis on how to derive material parameters from typical site investigation and laboratory soil data. The results of specific parametric studies are presented to support the suitability of the adopted analysis approach, also with regard to the adoption of alternative preloading procedures. The constitutive modelling of time-dependent clay’s behaviour is shown to play a crucial role in the considered framework, and will require further research for 3D FE modelling to provide reliable quantitative support to real wind farm installation projects.

Optimal Load Redistribution in Distribution Systems Using a Mixed-Integer Convex Model Based on Electrical Momentum

This paper addresses the problem concerning the efficient minimization of power losses in asymmetric distribution grids from the perspective of convex optimization. This research’s main objective is to propose an approximation optimization model to reduce the total power losses in a three-phase network using the concept of electrical momentum. To obtain a mixed-integer convex formulation, the voltage variables at each node are relaxed by assuming them to be equal to those at the substation bus. With this assumption, the power balance constraints are reduced to flow restrictions, allowing us to formulate a set of linear rules. The objective function is formulated as a strictly convex objective function by applying the concept of average electrical momentum, by representing the current flows in distribution lines as the active and reactive power variables. To solve the relaxed MIQC model, the GAMS software (Version 28.1.2) and its CPLEX, SBB, and XPRESS solvers are used. In order to validate the effectiveness of load redistribution in power loss minimization, the initial and final grid configurations are tested with the triangular-based power flow method for asymmetric distribution networks. Numerical results show that the proposed mixed-integer model allows for reductions of 24.34%, 18.64%, and 4.14% for the 8-, 15-, and 25-node test feeders, respectively, in comparison with the benchmark case. The sine–cosine algorithm and the black hole optimization method are also used for comparison, demonstrating the efficiency of the MIQC approach in minimizing the expected grid power losses for three-phase unbalanced networks.

Serial Quantitative Assessment of Load Redistribution After Medial Open-Wedge High Tibial Osteotomy.

The maximum standardized uptake value (SUVmax), as determined on combined single-photon emission computed tomography and conventional computed tomography (SPECT/CT), can be an indicator of biomechanical changes due to the load redistribution effect after medial open-wedge high tibial osteotomy (MOW-HTO). The purposes of this study were to (1) analyze serial changes in the SUVmax in the medial, lateral, and patellofemoral compartments after MOW-HTO and (2) identify the contributing factors that affect changes in the SUVmax. The hypotheses were that (1) an elevated SUVmax in the medial compartment would be transferred to the lateral compartment because of the load redistribution effect and (2) there would be contributing factors that cause SUVmax changes. Case series; Level of evidence, 4. Included were 67 knees that were treated with biplanar MOW-HTO between March 2019 and December 2020. SPECT/CT was performed immediately after surgery and at 3 months and 1 year postoperatively to determine the serial load redistribution effect of MOW-HTO. The Pearson correlation coefficient was used to evaluate the relationship between SUVmax and radiological parameters, and subgroup analyses were conducted to compare the SUVmax according to associated cartilage procedures and the weightbearing line ratio (WBLR). The SUVmax in the medial and lateral compartments increased at 3 months but decreased at 1 year postoperatively. The load redistribution effect was most prominent in the anterior zones of the femur (medial: P = .041; lateral: P = .012). In the patella, the SUVmax decreased in both the medial and the lateral zones at all follow-up times (P < .001 for all). The SUVmax in the anterolateral and posterolateral articular zones of the femur increased with a greater preoperative WBLR (r = 0.256, P = .039; and r = 0.261, P = .036, respectively). Patients who underwent an associated cartilage procedure had a significantly higher SUVmax in the anteromedial and posteromedial articular zones of both the femur and the tibia at 1 year postoperatively (P ≤ .002 for all). After MOW-HTO, the unloading effect in the anteromedial articular zone of the femur was the most significant. A greater SUVmax in the lateral zones of the femur was observed in cases of overcorrection. The SUVmax in the medial zones was higher postoperatively in patients with associated cartilage procedures.

Migration of VNF instances for service continuity

Fog computing computes and stores data locally based upon distributed architectures that extend cloud to the edge of the network. This enables fog paradigms to be suitable for delay‐sensitive applications that demand various network functions (NFs). These NFs here are provided using network function virtualization (NFV) to allow elastic NF deployment on the fog nodes, that is, virtual network functions (VNFs). Now a major challenge for NFV‐based fog architectures is the limited resources, which vulnerate them to premature saturation and load imbalance. Hence resource management schemes are necessary for fog networks, in particular load migration and redistribution. Along this, an efficient migration scheme is proposed here using the coordinated generalized pattern search (CGPS) heuristic method. The scheme migrates excess load from heavily‐loaded (HL) nodes to lightly‐loaded (LL) nodes in proximity. The scheme adopts two criteria, termed as exclusive and common use of VNF instances. Results show that the proposed scheme achieves high migration success at reduced delays, as well as alleviating resources with low migration frequency.

On the effect of soil water saturation on buried steel pipe responses under external load

Soil water saturation affects soil behavior when subjected to external loads and thus buried pipe deformation. To investigate this effect, full-scale tests were conducted on a buried steel pipe with a diameter of 600 mm. The deformed pipe ring transforms from a “heart” shape into an inclined “heart” shape due to the load redistribution within the soil after increasing soil water saturation. Then, a three-dimensional finite element model was created and validated based on the experimental data. A parametric study was thereafter performed to investigate the impact of factors including soil water saturation, cover depth, and pipe wall-thickness on buried pipe responses when subjected to external loads. Soil might be simply modeled as a linear elastic material at a large cover depth (&gt;0.6 m) or a water saturation &lt; 80%. Soil plasticity should be considered at a relatively low cover depth (≤0.6 m) and a high water saturation (≥80%). The pipe circumferential stress is inversely proportional to the square of pipe wall-thickness when the pipe–soil stiffness ratio is equal to or greater than 0.13.

Damage identification in cable-stayed bridges based on the redistribution of dead and thermal loads

Based on the response of a bridge to various excitations, Structural Health Monitoring (SHM) systems can provide comprehensive, real-time insight into their condition. While collected data usually represents the response to a combination of known and unknown loads, modified data, cleaned of the effects of dynamic loadings, can be made to represent the response of the structure to only constant dead loads and slowly changing and easily measured cyclic thermal loads. While it is often common to separate the effect of these two loads, the proposed method suggests that it is advantageous to consider the combined effect. Furthermore, once a limited amount of response data due to these loads has been collected, their combined effect can be easily predicted.A simplified model, consisting of the key structural components of a cable-stayed bridge, a beam, an inclined cable, and a bearing, and a more complex, that of a Finite Element cable-stayed bridge model, were used to evaluate the ability of the proposed method for identifying changes in these three elements. Beam damage was simulated as a flexural stiffness reduction for part of the beam, cable damage as an axial stiffness reduction of the cable and the bearing damage as a stiffness increase of a horizontal spring supporting the free to roll end of the beam. Using the model, it was shown that the behavior of two parameters, the slope and the intercept taken from the beam strain-temperature curve, can be used to not only identify change/damage to these members, but more importantly, determine the nature of the change/damage. Combined with the fact that the method has limited requirements for collecting, storing, and processing data, the proposed methodology represents a very promising Damage Identification tool.

Numerical study on the effect of protective wall depth in reducing structure deformations caused by tunnelling

To reduce tunnelling induced damage of buildings, a ‘protective wall’ is sometimes constructed between the location of the new tunnel and existing foundations. One of the key design questions relates to the optimal wall depth, where further increase has a limited benefit in reducing structural distortions. This paper presents the results from finite element analyses used to study how protective walls reduce tunnelling induced damage to adjacent structures. A scenario where the protective is located very close to a tunnel is studied, which is considered to be of practical interest and a critical case concerning potential for building damage. The analyses consider a tunnel with a row of 4 piles (in sand) supporting a 5-storey steel frame running transverse to the tunnel direction, with a wall located between the tunnel and the first pile. Results show that the protective wall’s depth affects soil and pile settlements, the redistribution of loads applied to the piles (due to structure stiffness), and ultimately structural deformations and building damage. For the case considered, the optimal depth of the wall is approximately 1.25 times the tunnel axis depth; marginal reductions in pile settlements and building damage are obtained as wall depth is increased further.

Revealing the effect of structural components made of sandwich panels on loading the container transported by railroad

The object of this study is the processes of emergence, perception, and redistribution of loads in the supporting structure of a 1CC size container with end walls made of sandwich panels. To reduce the longitudinal load of the container under operational modes, the introduction of sandwich panels into its design is proposed. This solution is implemented on the example of its end walls as the most loaded component of the body in operation. The thickness of the sandwich panel sheet was determined, provided that the strength in operation is ensured. Mathematical modeling of dynamic load of a container with end walls made of sandwich panels placed on a platform car during shunting co-impact was carried out. It was established that taking into account the proposed improvement makes it possible to reduce the dynamic loads that the container perceives by 10 % compared to the typical structure. The results were confirmed by computer simulation of the dynamic load of the container. The models formed within the framework of the study were verified according to the F-criterion. The results of calculations for the strength of the container showed that the stresses in its structure are 15 % lower than those in the typical one. A feature of the findings is that the proposed improvement of the container helps improve its strength in operation by reducing the loads acting on it. The scope of practical use of the results is the engineering industry, namely, railroad transport. At the same time, the conditions for the practical application of the research results are the introduction of energy-absorbing material as a component of the sandwich panel. This study will contribute to devising recommendations for designing modern structures of vehicles of a modular type and for improving the efficiency of the transport industry

Prediction of long-term differential track settlement in a transition zone using an iterative approach

A methodology for the simulation of long-term differential track settlement, the development of voided sleepers leading to a redistribution of rail seat loads, and the evolving irregularity in vertical track geometry at a transition between two track forms, is presented. For a prescribed traffic load, the accumulated settlement is predicted using an iterative approach. It is based on a time-domain model of vertical dynamic vehicle–track interaction to calculate the contact forces between sleepers and ballast in the short-term. These are used in an empirical model to determine the long-term settlement of the ballast/subgrade below each sleeper. Gravity loads and state-dependent track conditions are accounted for, including a prescribed variation of non-linear stiffness of the supporting foundation along the track model. In parallel, a two-dimensional (2D) non-linear finite element model of layered soil is verified versus field measurements and used to determine the support stiffness of each sleeper in the track model. The methodology is applied to a transition zone between a ballasted track and a slab track that is subjected to heavy haul traffic. Analyses of the influence of higher axle loads and the implementation of under sleeper pads on sleeper settlement are demonstrated.

Devising a method for balancing the load on a territorially distributed foggy environment

This study solves the task to redistribute the load on a geographically distributed foggy environment in order to achieve a load balance of virtual clusters. The necessity and possibility of developing a universal and at the same time scientifically based approach to load balancing has been determined. Object of study: the process of redistribution of load in a foggy environment between virtual, geographically distributed clusters. A load balancing method makes it possible to reduce delays and decrease the time for completing tasks on foggy nodes, which brings task processing closer to real time. To solve the task, a mathematical model of the functioning of a separate cluster in a foggy environment has been built. As a result of modeling, the problem of finding the optimal distribution of tasks across the nodes of the virtual cluster was obtained. The limitations of the problem take into account the characteristics of the physical nodes of support for the virtual cluster. The process of distributing the additional load was also simulated through the graph representation of tasks entering virtual clusters. The task to devise a method for load transfer between virtual clusters within a foggy environment is solved using the proposed iterative algorithm for finding a suitable cluster and placing the load. The simulation results showed that the balance of the foggy environment when using the proposed method increases significantly provided the network load is small. The scope of application of the results includes geographically distributed foggy systems, in particular the foggy layer of the industrial Internet of Things. A necessary practical condition for using the proposed results is the non-exceeding the specified limit of the total load on the foggy medium, usually 70 %

Centrifuge investigation of soil–foundation–superstructure interaction under static loading

Extensive efforts have been made to investigate soil–structure interaction (SSI) through numerical simulations whereas little experimental research is reported that tests the applicability of existing numerical models to SSI problems. To provide such experimental data, a unique series of experiments with 3D-printed aluminium framed structures supported by isolated spread footings were conducted in a geotechnical centrifuge. The centrifuge models included equipment and instrumentation that allowed the application of a uniformly distributed static load to the structures as well as the measurement of column loads and foundation movements. The effect of the stiffness of the structure relative to that of the soil was evaluated by varying the number of storeys in the structures and the type/relative density of foundation soils. The variability of soil properties was also studied by modifying the support conditions at single columns at various plan locations of the structure. It is shown that there is appreciable load redistribution in the superstructure, the amount of which depends primarily on the relative structure–soil stiffness and the location of weak and/or rigid foundations. The comparison between the centrifuge test results and the predictions from a simple numerical model with the footings simulated by appropriate linear elastic springs indicates that such a simple numerical model can provide a reasonable prediction of SSI.

Efficacy of Proprioceptive Training on Plantar Pressure and Jump Performance in Volleyball Players: A Proof-of-Principle Study.

Volleyball players are often subject to micro-traumatisms of the heel fat pad and ankle injuries. Recently, mat-based proprioceptive training has assumed a key role in recovery from these disorders. Therefore, this proof-of-principle study aimed to assess the efficacy of proprioceptive mat training on plantar pressures and athletic performance in volleyball players. The participants included adult semi-professional volleyball players allocated into two groups: an experimental group, with mat-based proprioceptive and balance training, and a control group, with a sham protocol. For the outcome, we evaluated the barefoot plantar pressure, performing an analysis on a baropodometric resistive platform. The countermovement jump and squat jump were measured using an inertial measurement unit. Nineteen subjects were included in the two groups: the active proprioceptive group (n = 10) or the control group (n = 9). The results show a more uniform redistribution of loads with pressure hindfoot relief in the experimental group compared to the control group (p = 0.021, RBC = 0.67). Moreover, we observed a significant increase in peak landing force and high concentric power development in the experimental group compared to the controls. Focused proprioceptive management provided hindfoot load attenuation by stimulating higher peaks of concentric force in the experimental group compared to the sham group. Even though the study included a small sample, the results obtained in this proof-of-principle study suggest a positive role of proprioceptive stimulation in the inter-seasonal scenario for volleyball players to improve their jump performance and reduce the micro-traumatisms of the heel fat pad and the ankle injury rate. However, further studies performed on larger samples are needed to confirm these preliminary results.

A Practice-Oriented Proposal to Consider the Flange Effect in Equivalent Frame Modeling of Masonry Buildings

This paper focuses on the so-called “flange effect” in unreinforced masonry buildings when the connection among walls is good, thus forming a 3D assembly of intersecting piers (with L-, C-, T-, or I-shaped cross-sections). Given the direction of the horizontal seismic action, the presence of such flanges (the piers loaded out-of-plane) can influence the response of the in-plane loaded pier (the web) in terms of failure modes, maximum strength, and displacement capacity. Specific rules are proposed in codes to evaluate the effective width of the flange, for the in-plane verification of a single masonry wall. However, in the case of 3D equivalent frame (EF) modeling of the whole building, all the intersecting piers should be considered entirely, to model the response in both the orthogonal directions as well as the torsional behavior, but this may lead to overestimating the flange effect if a perfect connection is assumed. This paper investigates the capability of simulating the actual behavior in EF models by introducing an elastic shear connection at the intersection between two piers using an “equivalent beam”, coupling the nodes at the top of piers. A practice-oriented analytical formulation is proposed to calibrate such a flange effect on the basis of the geometric features and material properties of the web and the flange. Its reliability is tested at the scale of simple 3D assemblies and entire buildings as well. Finite element parametric analyses on masonry panels with symmetrical I- and T-shaped cross-sections have been performed to investigate the axial load redistribution between the flanges and the web and the consequent repercussion on the overall performance of the web. The results have proven that, after a calibration of the shear connection, the variation of axial force between the web and the flanges is correctly reproduced and the strength criteria for 2D panels provide reliable results. Finally, in the conclusions, some practical hints for simulating an imperfect wall-to-wall connection are also provided, since this case is relevant in historic masonry buildings, which are characterized by different masonry types, transformations over time, and already-cracked conditions.

Load Redistribution-based Reliability Enhancement for Storage Area Networks

Storage area networks (SANs) are one of the prevalent reliable data storage solutions. However, cascading failures triggered by data overloading have become a major threat to SANs, preventing the desired quality of service from being delivered to users. Based on our preliminary works on studying the impacts of data loading on the reliability performance of SANs, this paper advances the state of the art by implementing node degree-based load redistribution strategies to enhance the SAN reliability, thus mitigating or even preventing the occurrence of cascading failures during the mission time. Load-based and reliability-based node selection rules are considered, which choose nodes with the highest load level and the lowest reliability for load redistribution, respectively. The relationship between data loading and reliability of an individual SAN component is modeled using the accelerated failure-time model with the power law. The SAN reliability is assessed using a combinatorial decision diagram-based approach. The application and effectiveness of the proposed load redistribution strategies are demonstrated and compared through a case study of an SAN with the mesh topology.

Anatomical features of the muscles of the pelvic limb in hares

The article reflects the data on anatomical features of pelvic limb muscles of representatives of hares (rabbit, hare). We studied 2 rabbit species - mestizo rabbits of unknown origin with body weight 1,5-2 kg, rabbits of Soviet chinchilla breed in cage keeping with body weight 5 kg and hare from natural habitat at the age of 1 year to 2 years without external signs of pathology. Based on the results of anatomical macro- and micropreparation, functional analysis of the studied structures the characteristic of pelvic limb muscles in a rabbit was presented, the features of the structure of pelvic limb muscles in a hare-rusak were revealed, a comparative morphological analysis of muscles in the studied animals with regard to biomechanical features of their motor behavior was performed. The study was carried out at the department of animal anatomy and histology named after Professor A.F. Klimov, K.I. Skryabin Moscow State Biomedical Institute. The methods used were conventional and fine anatomical dissection followed by description and analysis of the structures under study. As a result of the studies, general regularities and specific features of the anatomical structure of the pelvic limb muscles in the studied representatives of hares, caused by the specificity of the animals' motor behavior, were revealed. They are expressed in more powerful development of fascial formations in rabbit in comparison with hare at the simultaneous decrease in the degree of their consolidation with the skeletal musculature, which may reflect a special type of the statolocomotor act inherent in this species of animal. In addition, the integral role of fasciae in ensuring the unity of functions of the musculoskeletal system organs (load redistribution during intensive movement of the animal) is confirmed, which is reflected in their complex association with the muscles of the hip group. In the rabbit, the variability of differentiation of the tail muscle, adapted to the differences in the mass-size characteristics of the animal and the habitat, was also noted. The data obtained during the study are basic and can be used in modeling myopathies, enthesopathies and developing objective methods of their diagnosis and treatment.
