A Comparative Study of Analyzing the Impact of Various RCC Building Shapes on Wind Performance

The analysis, design, and creation of high-rise buildings necessitate a comprehensive information of wind-induced vibration, a critical factor that considerably impacts structural integrity. In this context, the existing study undertakes an exploration of the results of wind load on diverse building shapes, aiming to envision the most structurally stable configuration for multi-storey structures. Focusing usually on L-form and H-form buildings, the studies conduct a comparative evaluation to assess how wind load influences those distinct shapes. Each case study represents a structure located in Wind zone IV with Terrain category II, adhering to the specs mentioned in IS 875(part-3): 2015 standards. Emphasizing reinforced concrete (RCC) framed structures, the research delves into the repercussions of wind loads on critical parameters including maximum shear force, bending moment, and storey displacement. The resulting data is meticulously presented through tables and charts, elucidating the overall performance metrics for every case (H-shape and L-form) in terms of storey displacement, shear force, bending moment, and axial force. Eventually, an intensive evaluation is conducted to determine any disparities in structural behaviour and reaction to wind loads a number of the various constructing shapes, providing precious insights into most efficient design concerns for enhancing structural stability and resilience in excessive-rise constructions.

Energy-efficient torque distribution strategy for four wheel drive electric vehicles based on Traffic zone

This paper presents a four-wheel electric vehicle control system. It incorporates a two-level control strategy for stability and optimal torque distribution to improve fuel efficiency and extend the vehicle’s operational range. The control architecture is structured hierarchically, with a higher level responsible for determining yaw moment and traction forces based on the desired vehicle dynamics. At the lower level, a multi-criteria constrained optimization method is employed, considering both vehicle stability and energy consumption. Additionally, this study takes into consideration the vehicle’s operational context, such as the specific Traffic zone, and the adhesion properties of the tires. This ensures a delicate balance between instantaneous power consumption and overall vehicle stability. The control system’s performance is tested and assessed through three distinct scenarios within the Matlab/Simulink environment. The co-simulation involves the nonlinear vehicle model simulation software, Carsim, and the results are comprehensively compared to the literature.

Analysis of the Behaviour of Composite Connections in Multi-Storey Buildings Under Earthquake Loading

In the past years, number of beams and slabs in steel structures that are executed as composite steel – concrete elements has significantly increased. In moment-resisting frames with composite steel – concrete slabs, slab reinforcement in tensile zone needs to be considered in design of composite steel – concrete beam – to – column connections with steel plates and bolts in tensile zone. However, the number of reinforcement bars that should be taken into account in connection design significantly depends on the effective width of the concrete slab. Moreover, directions for calculation of the effective width of the concrete slab are still not unambiguous as they can be calculated either according to recommendations from Eurocode 4 or Eurocode 8. In this paper, composite connections are briefly explained and main differences between composite steel – concrete beam – to – column connections and corresponding steel connections are summarized. Furthermore, behaviour of a composite steel – concrete beam – to – column connection under bending moment and shear force induced by earthquake loading is investigated using finite element analysis in software package Abaqus. Finally, a parametric study is carried out in order to examine the suitability of two code recommendations for determination of the effective width of concrete slab in case of seismic loading.

Design of Fibre-Reinforced Concrete Structures

Different types of concrete are invented in the past years, in order to improve it`s behaviour for different loading and environmental situations. Among them, fibre reinforced concrete (FRC) is one of the most recently developed concrete types. Design procedures for the FRC elements are included in only a few existing code provisions. Among them, fib Model Code 2010 (MC 2010) provides the biggest amount of necessary information and recommendations in order to design FRC elements. Yet, a lack of the guidelines for the design of elements loaded with different combinations of bending moment and axial force is noticed in the existing code provisions. Therefore, in the scope of this paper, interaction curves for FRC are developed. The interaction curves are developed for both, ultimate limit state (ULS) and serviceability limit state (SLS). Furthermore, example of the use of such interaction curves is given. Comparison in the design of reservoir made of reinforced concrete (RC) and FRC is performed. It is shown that the use of FRC especial benefits design according to SLS, as FRC provides better behaviour regarding crack spacing and crack width of element, while developed interaction curves for SLS significantly decrease the time necessary for such a design.

A Passive Polycentric Mechanism to Improve Active Mediolateral Balance in Prosthetic Walking.

Prosthetic legs are typically passive systems without active ankle control, restricting mediolateral balancing to a hip strategy. Resulting balance control impairments for persons with a lower extremity amputation may be mitigated by increasing hip strategy effectiveness, in which relatively small hip moments of force are adequate for mediolateral balancing. To increase hip strategy effectiveness we have developed a prosthetic leg prototype based on the Peaucellier mechanism, the Sideways Balance Mechanism (SBM). This polycentric mechanism adds a frontal plane degree of freedom, reducing mediolateral body displacements. Adding a passive joint alone introduces instability, in which mediolateral body rotation leads to CoM height loss, ultimately resulting in a fall. The SBM however provides stability typically absent by lengthening under rotation, thereby compensating for CoM height loss. By allowing for both foot rotation (in-/eversion), and increased mediolateral ground reaction force the SBM increases hip strategy effectiveness. We aimed to provide proof of principle that the SBM can improve active mediolateral balance control in prosthetic walking by increasing hip strategy effectiveness compared to a typical set-up. Comparison between a typical set-up and the SBM showed an increased mediolateral ground reaction force at equal hip moments of force for a 2D forwards dynamics computer simulation, and a reduced hip moment of force at equal mediolateral ground reaction force for a case study. Results validate increased hip strategy effectiveness of the SBM compared to a typical set-up, providing proof of principle that adding an SBM to a prosthetic set-up improves mediolateral balance control in prosthetic walking.

Evaluation of Sit-to-Stand Movement Focusing on Kinematics, Kinetics, and Muscle Activity after Modern Total Knee Arthroplasty

The sit-to-stand (STS) movement is important in improving satisfaction after total knee arthroplasty (TKA). Reports on motion analysis using a combination of motion capture systems, force plates, and surface electromyography after TKA are limited. We aimed to compare the STS movement of patients aged over 60 who underwent modern and conventional TKA with more than 6 months of postoperative follow-up. Ten patients underwent surgery with a modern implant (Group I: Smith and Nephew JOURNEY II, Memphis, TN, USA), and ten with a conventional implant (Group II: Smith and Nephew LEGION, Memphis, TN, USA). STS movement kinematics and kinetic data were measured by synchronising a motion capture system with a force plate. Surface electromyography was used to measure the muscle activity. STS time was shorter in Group I than in Group II. Maximum knee-extension angular velocity and maximum knee-extension moment were greater in Group I than in Group II. Electromyography revealed that Group I tended to have less activity in the quadriceps femoris than Group II. Group II had a greater hip-extension moment and vertical ground reaction force, and the hip joint seemed to compensate for knee function. Group I possibly used the quadriceps muscle more effectively, due to the implant shape.

Evaluation of the complexity of the motor task from the point of view of muscle activation

Today, many specialists from various fields, such as physiology, biology, rehabilitation, traumatology and others, are actively researching the functioning of the musculoskeletal system and its relationship with the central nervous system. This is a very relevant topic in today's world, as various factors such as traumatic injury, chronic or hereditary disease, neurological impairment and the aging process have a direct impact on the state of the musculoskeletal system, muscle function and movement coordination. One of our goals is to study the dynamics of two-joint equilibrium muscle contraction in order to determine the final forces created by the right upper limb of a person in the horizontal plane. We are conducting a study in which the electromyographic (EMG) activity of the muscles of the shoulder and shoulder girdle, as well as the spatial and force parameters of movements that occur during free two-joint efforts, are studied. The purpose of this study is the process and mechanism of central coordination of motor commands sent to the muscles of the shoulder and shoulder girdle during bicondylar movements, especially when performing targeted efforts with the hand, in the presence of visual control. Synchronization and coordination of the muscles of the shoulder and shoulder girdle during the performance of two-joint movements were studied in an experiment with experimental subjects. By recording the electromyographic activity of 8 muscles and calculating the moments of forces generated by the muscles, it was found that muscle synchronization was more pronounced during elbow flexion, and muscle coordination - during shoulder extension. The findings of the study indicate that the muscles of the shoulder and shoulder girdle work in a synchronous and coordinated mode during two-joint movements. Muscle synchronization and coordination appeared to be important for precise movement control, with elbow flexion and shoulder extension showing greater accuracy compared to other movements.

Tidal effects in 4D-charged Einstein-Gauss-Bonnet gravity black hole

In this paper, we study the geodesic deviation between two nearby geodesics. For this process, we calculated the geodesic equation and radial motion of test particles. Also, the radial and angular tidal forces have been investigated using the curvature tensor in tetrad form. The radial tidal forces in 4D charged Einstein-Gauss-Bonnet gravity black hole show a tidal effect with a small value of radial coordinate r. The angular tidal forces show converse behavior as compared to the radial tidal forces at the short value of radial coordinate r. The radial and angular tidal forces have the same behavior at the immense value of radial coordinate r. The geodesic deviation paths depend on the charge Q parameter and Gauss-Bonnet parameter α of the black hole. We have compared our result with the 4D uncharged Einstein-Gauss-Bonnet gravity black hole and Reissner-Nordström with consideration of two kinds of initial conditions.

The Effects of Different Drivers’ Steering Inputs on the Response of Heavy Ground Vehicles to Crosswind Disturbances

The general approach in the previous studies was to ignore the driver’s steering contribution to a vehicle while investigating the interactions between crosswind and vehicle. Therefore, the goal of this study is to find out how steering inputs by drivers affect a heavy-ground vehicle’s dynamic reaction to crosswinds. In the investigation, a two-way interaction between vehicle dynamics and aerodynamic simulations was employed. The steering inputs of drivers were modelled using a driver model taken from the previous literature that is able to reproduce the steering responses of a human driver. The study’s findings demonstrated that the steering inputs made by drivers significantly impacted how the vehicle responded to crosswinds. For instance, the greatest lateral displacement of the least skilled driver (Driver 1) was around 1.53 times the greatest lateral displacement of the most skilled driver (Driver 3) at the delay time of tδ,delay = 0.5 s in the steering input. Additionally, the maximum lateral displacement results of Driver 1 and Driver 3 at tδ,delay = 1.0 s became 1.39 and 1.56 times greater than their maximum lateral displacement results at tδ,delay = 0.5 s. Similarly, the total steering inputs of Driver 1 and Driver 3 at tδ,delay = 1.0 s were 1.4 and 2.2 times greater than their total steering inputs at tδ,delay = 0.5 s, respectively. In general, the results of a driver who is more skilled than Driver 1 (Driver 2) fall in between the respective results of Driver 1 and Driver 3. On the other hand, each driver’s total steering inputs at tδ,delay = 0.5 s were roughly the same as their total steering inputs at tδ,delay = 0 s. In all delay scenarios for the start of the driver’s steering inputs, the drivers’ steering inputs amplified the yaw moment applied to the vehicle. Meanwhile, they diminished the lateral force and roll moment.

EFFECTIVE OPTION OF REINFORCEMENT FOR REINFORCED CONCRETE TAPERED ELEMENTS

Despite a large number of experimental and theoretical studies on the resistance to shear and crack formation of tapered elements, there are no reliable data in the domestic and foreign literature on the distribution of stresses in such elements in areas near fractures of the faces.
 In the article, based on the results of experimental studies, an analysis of the stress-strain state of tapered elements is performed. The main design factors affecting the stress distribution, as well as the nature of the formation and development of cracks are revealed. It is established that in gable beams, inclined cracks are formed not only in the support zone, but also in the middle of the span directly at the ridge, even in the absence of transverse force. The features of the stress-strain state of the beams of the broken outline are associated with the occurrence of tangential stresses from the action of the bending moment and longitudinal force due to the variable height of the section of the element, as well as with the formation of local stress fields in areas near the fractures of the faces.
 Based on the data obtained on the basis of experimental and theoretical studies, an effective option for reinforcing ridge zones of reinforced concrete gable beams and frames is proposed.

Retinal hemorrhage variation in inertial versus contact head injuries

BackgroundAbusive head trauma (AHT) is frequently accompanied by dense/extensive retinal hemorrhages to the periphery with or without retinoschisis (complex retinal hemorrhages, cRH). cRH are uncommon without AHT or major trauma. ObjectiveThe study objectives were to determine whether cRH are associated with inertial vs. contact mechanisms and are primary vs. secondary injuries. Participants and settingThis retrospective study utilized a de-identified PediBIRN database of 701 children <3-years-old presenting to intensive care for head trauma. Children with motor vehicle related trauma and preexisting brain abnormalities were excluded. All had imaging showing head injury and a dedicated ophthalmology examination. MethodsContact injuries included craniofacial soft tissue injuries, skull fractures and epidural hematoma. Inertial injuries included acute impairment or loss of consciousness and/or bilateral and/or interhemispheric subdural hemorrhage. Abuse was defined in two ways, by 1) predetermined criteria and 2) caretaking physicians/multidisciplinary team's diagnostic consensus. ResultsPediBIRN subjects with cRH frequently experienced inertial injury (99.4 % (308/310, OR = 53.74 (16.91–170.77)) but infrequently isolated contact trauma (0.6 % (2/310), OR = 0.02 (0.0004–0.06)). Inertial injuries predominated over contact trauma among children with cRH sorted AHT by predetermined criteria (99.1 % (237/239), OR = 20.20 (6.09—67.01) vs 0.5 % (2/339), OR = 0.04 (0.01–0.17)).Fifty-nine percent of patients with cRH, <24 h altered consciousness, and inertial injuries lacked imaging evidence of brain hypoxia, ischemia, or swelling. ConclusionscRH are significantly associated with inertial angular acceleration forces. They can occur without brain hypoxia, ischemia or swelling suggesting they are not secondary injuries.

Experimental and numerical study on the high-speed ship hydrodynamics influenced by an interceptor with varied angle of attack

Efforts to improve the hydrodynamic performance of high-speed ships have been underway for a long time. There are different approaches, one of which is to take advantage of an interceptor. Conventionally, the interceptor blades are mounted vertically on the ship's bottom transom, oriented at a zero-degree angle of attack (AoA). This study comprehensively explores high-speed ships' hulls with and without interceptor configurations, encompassing both negative and positive AoA of the interceptor, conducted through experimental and numerical methods using a fully captive model. The interceptors are strategically positioned and configured. Each configuration was examined under varying AoA settings, with uniform interceptor depths and systematic trim angle adjustments. The Computational Fluid Dynamics (CFD) approach simulates the local flow dynamics around the hull, thoroughly analyzing resistance, pressure distribution, lift force, wave profile, and trim moment. The results indicate that interceptor placement near the keel with AoA adjustments significantly reduces hydrodynamic resistance, while AoA changes have limited impact in other positions. Lift force analysis shows interceptors improve lift compared to the bare hull, but this improvement is not linear across positions. Furthermore, it is observed that adjustments in AoA influence lift, with a negative AoA generally being considered favorable. In summary, carefully considering placement, AoA, and height-to-length ratio is necessary to maximize interceptor advantages.

Predicting Leg Forces and Knee Moments Using Inertial Measurement Units: An In Vitro Study.

We compared the ability of seven machine learning algorithms to use wearable inertial measurement unit (IMU) data to identify the severe knee loading cycles known to induce microdamage associated with anterior cruciate ligament rupture. Sixteen cadaveric knee specimens, dissected free of skin and muscle, were mounted in a rig simulating standardized jump landings. One IMU was located above and the other below the knee, the applied three-dimensional action and reaction loads were measured via six-axis load cells, and the three-dimensional knee kinematics were also recorded by a laboratory motion capture system. Machine learning algorithms were used to predict the knee moments and the tibial and femur vertical forces; 13 knees were utilized for training each model, while three were used for testing its accuracy (i.e., normalized root-mean-square error) and reliability (Bland-Altman limits of agreement). The results showed the models predicted force and knee moment values with acceptable levels of error and, although several models exhibited some form of bias, acceptable reliability. Further research will be needed to determine whether these types of models can be modified to attenuate the inevitable in vivo soft tissue motion artifact associated with highly dynamic activities like jump landings.

Numerical solution for the laterally loaded rigid piles considering resisting force and moment under combined loadings

A numerical method is first proposed for the response of laterally loaded rigid piles under lateral load based on the curved strain wedge model. The influence of shear displacement of the pile, resistance bending moment caused by the uneven vertical shear stress on the pile side and resistance force and bending moment at the pile bottom are all considered. The effect of the vertical load on the lateral response of the monopile foundation is then analyzed according to the practical fact that the piles are always subjected to combined loads. The vertical friction force on the pile side is derived by combining vertical load and horizontal bending of the pile, and the resistance force at the pile bottom is determined by both vertical load and pile self–weight. The effect of P–Δ on the pile foundation caused by the vertical load is also considered. Several field tests are used to verify the reasonableness and accuracy of the proposed method. The influencing factors are studied. The results show that the vertical load has a favorable effect on the lateral response of the pile in frictional soil and almost no effect on the lateral response of the pile in frictionless soil.

Hip joint and muscle loading for persons with bilateral transfemoral/through-knee amputations: biomechanical differences between full-length articulated and foreshortened non-articulated prostheses

BackgroundCurrently, there is little available in-depth analysis of the biomechanical effect of different prostheses on the musculoskeletal system function and residual limb internal loading for persons with bilateral transfemoral/through-knee amputations (BTF). Commercially available prostheses for BTF include full-length articulated prostheses (microprocessor-controlled prosthetic knees with dynamic response prosthetic feet) and foreshortened non-articulated stubby prostheses. This study aims to assess and compare the BTF musculoskeletal function and loading during gait with these two types of prostheses.MethodsGait data were collected from four male traumatic military BTF and four able-bodied (AB) matched controls using a 10-camera motion capture system with two force plates. BTF completed level-ground walking trials with full-length articulated and foreshortened non-articulated stubby prostheses. Inverse kinematics, inverse dynamics and musculoskeletal modelling simulations were conducted.ResultsFull-length articulated prostheses introduced larger stride length (by 0.5 m) and walking speed (by 0.3 m/s) than stubbies. BTF with articulated prostheses showed larger peak hip extension angles (by 10.1°), flexion moment (by 1.0 Nm/kg) and second peak hip contact force (by 3.8 bodyweight) than stubbies. There was no difference in the hip joint loading profile between BTF with stubbies and AB for one gait cycle. Full-length articulated prostheses introduced higher hip flexor muscle force impulse than stubbies.ConclusionsCompared to stubbies, BTF with full-length articulated prostheses can achieve similar activity levels to persons without limb loss, but this may introduce detrimental muscle and hip joint loading, which may lead to reduced muscular endurance and joint degeneration. This study provides beneficial guidance in making informed decisions for prosthesis choice.

VERIFICATION OF THE MATHEMATICAL FLIGHT MODEL THE PROJECTILE AS A MODIFIED MODEL OF THE MATERIAL POINT

The analysis of mathematical models of the flight of projectiles has been carried out, it is shown that the nature of their provision varies depending on the degree of reliability of the representation of the real physical process of its flight by a mathematical model, the adequate consideration of certain forces (moments) acting on the projectile, as well as the level of information about external flight conditions. In the simplest mathematical model with three degrees of freedom, the projectile is considered as a material point that moves in the atmosphere under the influence of gravity and full aerodynamic force. The dynamics of projectile flight is most completely described by the mathematical model of the movement of a solid body with six degrees of freedom. In the intermediate model with four degrees of freedom, all aerodynamic forces are taken into account, the orientation of the projectile is characterized by taking into account the angle of nutation, and the kinetic energy of the rotational movement is taken into account through the angular velocity of the projectile around its axis of symmetry. The process of restori ng the coefficients of aerodynamic forces using the material point model does not provide the necessary accuracy and adequacy of the description of the projectile flight process; of the modified material point model is much simpler (the least complex) compared to the model of the motion of a rigid body with six degrees of freedom due to the smaller number of coefficients and differential equations included in its composition. The differential equations of the modified material point model are provided - the equation of motion of the center of mass and the equation of nutational oscillations of the projectile in scalar form; an assessment of its accuracy (adequacy) was carried out on the example of the 155-mm PF projectile M2000, one of the family of projectiles of the company Denel Naschem – Assegai M200X Series 155-mm Projectiles. A comparison of the characteristics of the 155-mm PF of the M2000 projectile calculated according to the 6DoF model and the modified material point model showed their high convergence; the error does not exceed 1%. Keywords: aerodynamic forces (moments), projectile, mathematical models, modified model, aerodynamic coefficients, simulation, accuracy, flight parameters.

Mechanical response of concrete pipe rehabilitated by liner under external load: Analytical solution

AbstractUsing pipe lines to rehabilitate concrete drainage pipes is a popular trenchless technique. In this paper, the concrete pipe and liner are equivalent to a symmetrical structural mechanics problem, and the mechanical solution of the composite structure is obtained using the force method. Subsequently, the analytical solutions are compared with the test and finite element results. The distribution law of axial force, bending moment, and shear force of the composite structure are obtained, and the circumferential strain law of the inner and outer surfaces of the host pipe is analyzed. Lastly, the influence of pipe diameter and liner thickness on the bearing capacity of the host pipe is examined. The results indicate that the axial and shear force distribution of the composite structure remains the same for different pipe diameters, as the distribution diagrams of shear and axial force along the circumferential direction coincide. While the elastic modulus and thickness of the liner have no effect on the internal force distribution of the composite structure, they do directly affect the stress state of the host pipe. Additionally, the bottom support causes abrupt changes in the bending moments and strains of the host pipe.

Coordination of hip and spine in individuals with acute low back pain during unstable sitting

BACKGROUND CONTEXTTrunk postural control differs between individuals with and without chronic low back pain. Whether this corresponds to differences in hip/spine coordination during the early acute phase of LBP (ALBP) is unclear. PURPOSETo compare hip/spine coordination in relation to seat movements between individuals with and without ALBP when balancing on an unstable seat and to identify coordination strategies to maintain balance using cluster analysis. STUDY DESIGN/SETTINGCross-sectional observational study. PATIENT SAMPLEALBP (n=130) and pain-free (n=72) individuals. OUTCOME MEASURESFrequency domain measures to evaluate hip/spine coordination (amplitude spectrum, phase angle, coherence) and time-series measures to assess overall balance performance (centre of pressure [CoP] reflecting the amount of seat movements, upper thorax motion as a surrogate for head motion). METHODSParticipants maintained balance while sitting on a seat fixed to a hemisphere. Seat, hip and spine (lower lumbar, lumbar, upper lumbar, thoracic) angular motion and force plate data were recorded. RESULTSOverall, seat/CoP movements (amplitude spectrum and RMSdisplacement) were greater (in both planes) and sagittal coordination (coherence) between the hip or lower spine and seat movements was lower in ALBP than controls. Cluster analysis using coherence data revealed different coordination strategies to maintain balance. Separate clusters used a “lower lumbar strategy” and “hip strategy” in the sagittal plane, and a “lower and upper lumbar strategy” and “lower lumbar strategy” in the frontal plane. A cluster using a “low coherence strategy” in both planes was also identified. CONCLUSIONSHip and lower spine coordination was less in individuals with ALBP in conjunction with a lower quality of overall balance performance. However, interpretation of the relationship between coherence and overall balance performance was not straightforward. Clusters in both the ALBP group and the control group adopted a low coherence strategy, and this was not consistently related to poor overall balance performance. This suggests overall balance performance cannot be inferred from coherence alone and requires consideration of interaction of other different features.

Research on simplified tire finite element modeling and simulation method

A simplified tire finite element model modeling and simulation method with high efficiency and accuracy is proposed to address the issues of poor efficiency and low accuracy in tire finite element simulation. Firstly, the detailed finite element model of the tire is established, and the viscoelastic material parameters are determined through theoretical analysis and simulation verification. Then, the Hyperelastic material parameters are obtained through cyclic Tensile testing, and finally, the static tire condition test verification is completed. Based on the established detailed finite element model of the tire, the influence of different rubber materials on the dynamic characteristics of the tire is studied. On this basis, simplified friction and structure models are proposed to complete the establishment of a simplified tire finite element model. The simulation results of lateral and longitudinal slip conditions are compared with experimental data by implanting a finite element friction model that considers slip velocity and contact pressure. Through simulation analysis, it was found that the tread compound has a significant impact on the dynamic characteristics of the tire, while other compounds have a relatively small impact. Simplifying the tire finite element model can significantly improve the efficiency of finite element simulation and reduce convergence issues. The comparison accuracy between the finite element model simulation results and experimental data is relatively high, with the average accuracy of longitudinal force, lateral force, and correction moment reaching 89%, 95%, and 81%, respectively. This verifies the correctness and effectiveness of the simplified tire finite element model modeling and simulation method. This method provides certain reference significance for improving the efficiency of tire finite element simulation and providing virtual matching between tires and the entire vehicle.
