Influence of parameters in flexural behavior of composite slabs

Composite steel–concrete deck slabs are used in floor construction in steel-framed buildings where the connection between steel beam and the concrete slab through shear connectors exploits the best combination of each component. The behavior of composite steel deck slab is investigated based on different parameters such as presence of embossments, shape and thickness of profile sheets, thickness of concrete slab, loading constraints, steel–concrete contact and end anchorages. Performance is evaluated on the basis of load carrying capacity, end slip, and the end anchorage contributions to the behavior of composite deck slabs. The finite element analysis is done using ANSYS software by varying different parameters and the influence factor of each parameter in the performance of composite deck slab is found by regression analysis and finally experiments are conducted to validate the study. Based on the parameters studied the trapezoidal sheets of 1.2 mm thickness with stiffeners shows a better performance.

Shear Strength Prediction of Reinforced Concrete Two-way Thick Slabs: Comparison between Experimental and Analytical Studies

This paper describes an attempt to perform analytical studies on shear strength prediction of reinforced concrete two-way thick slabs. To this end, twenty test data from four groups of researchers were adopted and compared against the shear strength predictions from five shear design equations (i.e., ACI 318-14, ACI 318-19, EC2, CSA, and SMCFT). The ability of these equations to provide accurate prediction was evaluated based on the ratio of test-to-calculated shear strength, coefficient of variation (COV), and distribution of test data against the equality line. From the results presented, it was shown that each shear design prediction varied considerably from one another. Regarding the accuracy, it was shown that the SMCFT design method was able to predict the shear strength more accurately and proved the development of theoretically-sound shear design with a simple and straightforward procedure worked well in this case. It was also shown that improved prediction was able to be captured by ACI 318-19 compared to its preceding version of ACI 318-14. ACI 318-19 was also shown to demonstrate more conservative predictions which were more comparable to SMCFT.

Half‐Integer Topological Charge Polarization of Quasi‐Dirac Bound States in the Continuum

AbstractThe non‐trivial polarization topology of bound states in the continuum (BICs) provides new strategies in nanophotonics. The polarization topology depends on the geometric parameters and energy‐momentum dispersion of the system and can be engineered to add specific functionalities for light molding. Herein, such a possibility is investigated by studying the topology of the polarization states associated with the optical field radiated by BICs when Dirac‐cone‐degeneracy is lifted. The opening of a pseudogap in the Dirac cone dispersion of square‐lattice dielectric photonic crystal slabs is achieved by tuning the slab thickness. First, the emergence of half‐integer topological charges without the requirement of BIC annihilation is theoretically shown, which instead occurs when in‐plane inversion symmetry is broken. Then, using spin‐to‐orbital angular momentum conversion, the theory of half‐integer topological charges mediated by BICs is demonstrated and experimentally proved. The same device is able to give rise to vortices with different orbital angular momentum depending on the way it is illuminated, thus improving the potential of optical multiplexing. In addition, the additive character of the topology‐induced phase‐vortex generation is finally demonstrated for both integer and half‐integer charges using also vortex states as input beams, which is of relevance for information delivery.

Prospects of the use of high-tension fiber concrete as the basis for the formation of protective shelters and fortification structures during the russian-ukrainian war

This article analyzes the current state of protective shelters and fortification structures, foresees the modern possibilities of using fastening and basalt-type structures to increase the stability of concrete fortifications both during the construction of buildings for the protection of the civilian population, and for the creation of dugouts, fortifications and fire structures for the protection of personnel in accordance.
 Studies of the physical and mechanical properties of fiber concrete modified with plasticizers and active mineral additives using basalt and polypropylene fibers have shown that their introduction has a positive effect on the strength characteristics of concrete. The compressive strength of fiber concrete at day 28 increases from 61.4 to 77.0 and 96.2 MPa, respectively, and the flexural strength from 7.4 to 12.7 and 13.8 MPa, respectively.
 For the production of reinforced concrete protective materials, it is more effective to create hybrid high-strength concrete using fibers of different nature, followed by the formation of a reinforced concrete slab of the appropriate size. At the same time, the standard provides for the manufacture of prefabricated reinforced concrete elements of fortification structures and platoon support points of wall panels of the SP-1, SP-2 type and floor slabs PP-1 with a thickness of at least 300 mm from heavy concrete of strength class C32/40 with the use of plasticizers and active chemical additives.
 However, when using the obtained hybrid fiber concrete with strength class C50/60 and using a reinforcing mesh according to the calculated data, it is possible to reduce the effective thickness of the fiber concrete slab to 27.5 cm installation of fortification.
 The use of a reinforcing mesh in a complex with basalt fiber provides increased resistance of fiber concrete to the action of a high-speed impact due to an increase in the density of the cementing matrix as a result of a decrease in water consumption, as well as due to spatial three-dimensional reinforcement with dispersed basalt fiber. As a result of the mutual combination of the strength characteristics of the concrete matrix at the micro- and macro-levels in hybrid fiber concrete, it is possible to reduce the thickness of reinforced concrete elements and reduce the weight of the protective structure while meeting the requirements of the standards for such fortifications. An increase in the strength of cement stone occurs due to a decrease in the concentration of stresses in places of local stresses and a redistribution of energy throughout the volume of the material.
 The conducted studies of modern hybrid high-strength concrete with basalt fiber create new opportunities for the creation of protective concrete fortifications and fortification structures.

Case Study: Effect of mechanical short-circuiting of isolation pads on rooftop equipment noise and vibration transfer to spaces below.

The authors conducted investigations into noise from large rooftop air source heat pump (HP) equipment to student housing units below in a new concrete building. The investigation included both airborne noise and vibration measurements on the roof and in the dwelling units below. A total of five, 18-Ton devices were mounted on a foam-filled concrete housekeeping pad resting on an 8-inch thick PT structural slab and isolated by means of spring mounts fitted with neoprene isolation pads below their baseplate. The dwelling units below had exposed concrete at the ceiling, shear walls, and columns. Noise from the HPs were waking residents in the units directly below the equipment. After a number of adjustments to the spring isolation mounts to eliminate bindings and mechanical short-circuits, the investigation showed that vibration was also being transmitted to the building structure from the isolator base plates through the anchor bolts, bypassing the noise pads below the baseplate. Removal of this secondary short-circuit resulted in noticeable reductions in both noise and vibration at the spaces below, highlighting the need for careful adjustment and the provision of additional isolation elements in the installation.

Laboratory measurements on replaceable jack-up systems

Floating floor systems are part of state-of-the-art modern building technology. They are an efficient option to improve the acoustical performance of buildings and can be part of box-in-box systems installed in high-performance spaces. There are many types of high-performance floating floor types, one of which is a jack-up system that guarantees that the floor is decoupled from the structural floor. With these systems, once the concrete has cured, the isolated slab is raised off the structure to the required void depth using pre-cast boxes. These boxes allow for easy adjustment of the final floor height and, if the use of the room or load conditions change in the future, can also allow the replacement of the isolators inside them. Replaceable and inspectable acoustical floor systems are perceived as systems with lower sound insulation (airborne noise) than traditional floating floor or non-replaceable jack-up systems. To measure airborne sound reduction and impact noise isolation of replaceable jack-up systems and confirm factors that can influence its performance, CDM Stravitec invested in a testing campaign, where measurements were made considering many variables, such as: concrete floating slab thickness; bearings type, air void depth, steel lid installed on top of each box and insulation material installed in the air void. This paper will present the

Clinical Characterization of a Table Mounted Range Shifter Board for Synchrotron-Based Intensity Modulated Proton Therapy for Pediatric Craniospinal Irradiation.

Purpose: To report our design, manufacturing, commissioning and initial clinical experience with a table-mounted range shifter board (RSB) intended to replace the machine-mounted range shifter (MRS) in a synchrotron-based pencil beam scanning (PBS) system to reduce penumbra and normal tissue dose for image-guided pediatric craniospinal irradiation (CSI). Methods: A custom RSB was designed and manufactured from a 3.5 cm thick slab of polymethyl methacrylate (PMMA) to be placed directly under patients, on top of our existing couch top. The relative linear stopping power (RLSP) of the RSB was measured using a multi-layer ionization chamber, and output constancy was measured using an ion chamber. End-to-end tests were performed using the MRS and RSB approaches using an anthropomorphic phantom and radiochromic film measurements. Cone beam CT (CBCT) and 2D planar kV X-ray image quality were compared with and without the RSB present using image quality phantoms. CSI plans were produced using MRS and RSB approaches for two retrospective pediatric patients, and the resultant normal tissue doses were compared. Results: The RLSP of the RSB was found to be 1.163 and provided computed penumbra of 6.9 mm in the phantom compared to 11.8 mm using the MRS. Phantom measurements using the RSB demonstrated errors in output constancy, range, and penumbra of 0.3%, -0.8%, and 0.6 mm, respectively. The RSB reduced mean kidney and lung dose compared to the MRS by 57.7% and 46.3%, respectively. The RSB decreased mean CBCT image intensities by 86.8 HU but did not significantly impact CBCT or kV spatial resolution providing acceptable image quality for patient setup. Conclusions: A custom RSB for pediatric proton CSI was designed, manufactured, modeled in our TPS, and found to significantly reduce lateral proton beam penumbra compared to a standard MRS while maintaining CBCT and kV image-quality and is in routine use at our center.

Near-field thermal modulator between nanoparticles based on the multilayered structure

• We develop the calculation model for radiative heat flux between arbitrary multiple nanoparticles placed on opposite sides of the multilayered slab. • The coupling of particle resonance and excited multilayered surface polaritons plays a dominant role in RHT between particles. • The phase change feature of VO 2 can achieve the dramatically active modulation of the RHT between two particles. • The impacts of particle-slab distance and the thickness of the multilayered slab on the thermal control effect are studied. • We can achieve various thermal modulation effects between particle clusters, including thermal switching, thermal modulation, and thermal amplification. We propose a near-field thermal modulator between nanoparticles based on a multilayered slab consisting of the phase change material. Initially, we present a calculation model for radiative heat transfer (RHT) between multiple nanoparticles placed on opposite sides of the multilayered slab. Subsequently, we proceed to analyze the case of two particles, demonstrating that the multilayered slab is capable of providing a robust transmission channel for RHT between the particles. This is achieved through the coupling of particle resonance and excited surface polaritons of the multilayer. Furthermore, the phase change feature can be utilized to switch the transmission channel, thereby achieving active modulation of the RHT. The impact of particle-slab distance and the thickness of the multilayered slab on the thermal control effect is investigated. Moreover, we explore the thermal modulation functions of the RHT in a more complex system where particle clusters are located on opposite sides of the multilayered slab, achieving various thermal modulation effects between particle clusters, including thermal switching, thermal modulation, and thermal amplification.

Greenland Ice Sheet Ice Slab Expansion and Thickening

AbstractWe use airborne accumulation radar data acquired over the Greenland Ice Sheet between 2002 and 2018 to identify changes in ice slab extent and thickness. We show that ice slabs several meters thick were already present at least as early as 2002. Between 2012 and 2018, they expanded by 13,400–17,600 inland, or 37%–44%. Our results document that the extremely warm summer of 2012 produced near‐surface ice layers at higher elevations, enabling ice slabs to develop with only moderate melting in the following summers. With repeat flights along a transect in southwest Greenland, we show that moderate melting primarily causes slab thickening through uniform accretion on top of the ice slabs, while large melting events can also trigger localized accretion below existing ice slabs.

Transverse Magnetic Mode Laser in Photonic Crystal Nanobeam Cavity

We experimentally demonstrate a transverse magnetic (TM) mode laser in a photonic crystal (PhC) slab structure at room temperature. This study proposes a PhC nanobeam (NB) cavity to support a high-quality-factor ($Q$-factor) TM mode. For a large and complete photonic band gap, the PhC NB structures consist of large air holes in a thick dielectric slab. The PhC NB cavity is optimized numerically for a high-$Q$-factor TM mode of over 1 000 000 by reducing the radii of the air holes quadratically from the center to the edge of the PhC NB. A single-TM-mode lasing action is observed in an In-Ga-As-P quantum well (QW)-embedded optimized PhC NB cavity structure at room temperature via optical pulse pumping, where the QW layer is lightly etched. We believe that the TM mode lasers in PhC NB cavities with a lightly etched QW can be good candidates for a surface plasmon excitation source or a highly sensitive optical sensor.

Experimental, numerical, and theoretical study of punching shear capacity of corroded reinforced concrete slab-column joints

Rebars in reinforced concrete (RC) slab-column systems are susceptible to corrosion in unfavorable environments, making slab-column joints (SCJs) more prone to punching shear (PS) failure. In this study, experimental, numerical, and theoretical studies of the PS capacity of corroded RC SCJs were conducted. Four RC SCJ specimens were constructed, and their reinforcement bars were exposed to accelerated corrosion using an electrochemical process. Subsequently, monotonic load tests were performed to determine the PS capacity of the RC SCJs with various corrosion levels. The test results demonstrated that rebar corrosion significantly reduces the PS capacity of the SCJs. Based on this outcome, an extended numerical study is executed to get a broader understanding of the corrosion effect on RC SCJs. A finite element model was devolved using Abaqus software, and the accuracy of the model was validated by the results of the four experimental specimens in the current study. Additionally, experimental results of large-scale specimens from the literature were also used to validate the numerical simulation. A two-level factorial design (TLFD) was used to examine the main and interactive parameters influencing the PS capacity and the ultimate deflection of the corroded RC SCJs. The parameters that were considered are the corrosion ratio, corrosion area, column rectangularity, slab thicknesses, reinforcement ratio, compressive strength of concrete, yield strength of reinforcement, and supporting distance. Based on the TLFD, the numerical parametric study was performed. The results of the numerical study show that corrosion can change the failure mode of the joints from flexural failure to punching shear failure and significantly reduces the PS capacity. The results indicate that increasing the rebar corrosion ratio or the corroded zone size decreases the PS capacity of a corroded SCJ. While increasing the slab thickness reduces the negative effect of rebar corrosion on the PS capacity. In addition, increasing the reinforcement ratio has a slight impact on improving the PS capacity. However, increasing the column rectangularity decreases the PS capacity of a corroded RC SCJ significantly. Based on the results of the experimental and numerical studies, an analytical model was developed to predict the punching shear capacity of the corroded RC SCJ. The reliability of the developed model was verified through the comparison with four different code provisions: ACI 318–19, CSA 23.3–14, BS 8110–97, and Eurocode 2, and three empirical models from the literature.

The Influence of Temperature Variations on Rigid Pavement Concrete Slabs

This research aims to assess the effect of temperature gradient developed within the concrete slab of rigid pavement, and to investigate its impact when incorporated with the traffic load, and the heat transfer pattern. The rigid pavement model considers an isotropic, uniform, and linear-elastic schemes to simulate the material properties. A numerical analysis approach was employed using Abaqus software incorporated with the 3D Solid model. The traffic loads were obtained from the field surveys, while the temperature of the slabs was measured directly on the site. The dimension of the rigid panel is 2.75 m in width, 5 m long, slab thickness of 25 cm, and concrete specification of 41.33 MPa. The results showed that the temperature gradient produced a significant impact on stress development within the concrete slab of rigid pavement. It was observed that the temperature gradient during the daytime generated higher stress than at night, with a value reaching the MOR (Modulus of Rupture). The exposure of the rigid pavement to 500C tends to produce a principle slab stress of 2.395 MPa, while 1.31 MPa was developed due to the traffic load. When the two factors were combined, the concrete slab acquired a maximum principle stress of 3.322 MPa, which is close to the MOR of 83.34% fa. These results showed that the pavement is capable of withstanding stress from temperature gradient and traffic load as indicated by the ratio of less than one (1). However, this ratio is high for fatigue failure mitigation purposes, and this reduces the quality of life of the rigid pavement.

An experimental and numerical investigation on the load transfer efficiency of a novel prefabricated cement concrete pavement

Prefabricated cement concrete pavement (PCCP) is utilized more frequently in airport projects. Load transfer efficiency (LTE) is an essential mechanical index of PCCP. This study proposes a novel PCCP surrounded by tongue and groove joints. It uses both physical and numerical modeling to perform the investigation, and the mechanical responses and the LTE of the novel PCCP are presented in the experiments. The experimental results showed that the presence of tenon and mortise causes a difference in the stresses of two longitudinal and two transverse joints. Subsequently, a finite element model is developed to simulate the PCCP with and without transverse tongue and groove joint. In addition, the influence of different slab thicknesses, joint rigidity, and base elastic modulus on LTE is also discussed. The findings demonstrated that the transverse joints change the pavement slab's stress state. The LTE of the slab without a transverse joint is slightly larger than that with a transverse joint, while the maximum horizontal tensile stress of the slab without a transverse joint is 395% higher than that with a transverse joint on average. It is also observed that increasing the joint rigidity improves the LTE, whereas increasing the slab thickness decreases the LTE, and increasing the base modulus has no discernible effect on the LTE. Comparing the experimental and numerical results reveals a good agreement.

Finite Element Analysis of the Bearing Capacity of Beamless Floor Slabs under Punching, Taking into Account the Design Parameters of the Contacting Elements

Static calculations of experimental models in an elastic formulation were carried out, and the regularities connecting the dependences of forces in the calculated cross-section of punching out from the main structural parameters of contacting elements (reinforced concrete slabs and pylons) and from the used concrete class were revealed. This article concerns the safety issues of reinforced concrete slabs under punching with different ratios and combinations of pylon and slab thickness parameters, as well as concrete strength. The objectives of the research are consideration of the fracture pattern of reinforced concrete monolithic slabs due to punching shear; comparative analysis of modern normative calculation methods and flat reinforced concrete slabs due to static punching shear; finite element modelling and analysis of the punching shear calculation results for reinforced concrete floor slabs; and the force distribution over the area of the contacting elements-saw and floor slab. The practical significance of the results lies in the use of the obtained forces in the contacting elements for the calculation and design of reliable structures of beamless floor slabs.

Developing a model of porous concrete-filled rigid pavement

To address several significant environmental challenges, such as recharging groundwater and reducing storm-water runoff, porous concrete is one of the most effective paving materials. No-fines concrete has been successfully used as a paving material for parking areas, residential streets, pedestrian walkways, and areas with light traffic. The application of porous concrete as a pavement material on major urban roads is challenging due to its low compressive strength. This study aims to assess the practicality of porous concrete-filled rigid pavement on high-volume roads using the Finite Element Model. The slab thickness is designed as per IRC: 58–2015. The commercial finite element software Abaqus is used to model the slabs and calculate the response of the rigid pavement when subjected to loading. Then the results obtained by Abaqus were compared with the results obtained by Westergaard’s equations. Using Abaqus, the behavior of porous concrete-filled rigid pavement is investigated and the model of porous concrete-filled rigid pavement is developed.

Machine-Learning-Based uncertainty and sensitivity analysis of Reinforced-Concrete slabs subjected to fire

Reinforced concrete (RC) slabs are integral parts of building structures and provide compartmentation functionality when subjected to fire. However, the fire resistance of RC slabs is affected by numerous factors that are mostly inherent uncertainties. Therefore, uncertainty and sensitivity analyses were conducted to examine the influence and significance of the potential uncertain parameters on the fire resistance of RC slabs. To this end, a set of RC slab samples with various design parameters were generated and different fire scenarios were considered using parametric fire curves. The slab samples were randomly coupled with the fire scenario samples. For each of the slab-fire pairs, finite-element simulations were conducted, and three specific fire durations were identified to represent the slab fire resistance corresponding to the failure criteria on the steel temperature (SP-Ⅰ), unexposed surface temperature (SP-Ⅱ), and mid-span deflection (SP- III). As a consequence, a database was established by collecting the calculated fire resistance for all the considered slab-fire samples. The prediction models of the slab fire resistance in association with uncertain parameters were developed by four commonly used ML algorithms, including linear regression, random forest, gradient boosting decision tree, and extreme gradient boosting. Among the developed ML-based prediction models, the extreme gradient boosting model was proven to have superior predictive accuracy. Therefore, it was further utilized for uncertainty analysis by considering 14 uncertain parameters from fire scenarios, material strengths, geometric dimensions, and external loads. The uncertainty analysis results showed that the considered uncertain parameters cause significant variability in the fire resistance of slabs, and the coefficients of variation were 11.5%, 13.1%, and 20.6% for the fire durations related to SP-Ⅰ, SP-Ⅱ, and SP- III, respectively. Moreover, the SHapley Additive exPlanations method was used to examine the sensitivity of the considered uncertain parameters. It was found that the parameters related to fire scenario were more influential to the fire resistance of slabs than the slab design parameters. The opening factor, slab thickness, and fire load density had noticeable effects on the fire resistance of SP-Ⅰ, SP-Ⅱ, and SP- III, respectively, whereas the uncertainties from material strengths and convection conditions had negligible effects.

The flat slab building is used these days because these structures offers many benefits which a normal slab structure does not provide .The objectives of this project is to compare multi-storey residential building having flat slab with conventional slab . The design and analysis is done by using ETABS software. This present work provides reasonable information about the stability of flat slab.

Experiment and Modelling on Effective Width of Single and Twin I-beam Composite Girders

Effective width (beff) has been widely used by designers, and several specifications can be selected. However, insufficient research has been conducted on the beff of single and twin I-beam composite girders. Thus, finite element (FE) models, calibrated by the experiment, were used to study the effects of slab thickness, web position, interaction degree (ID) of shear studs, width-to-span ratio, and their coupling effects on beff. Different loading types and two definitions of beff were elaborated. The FE results were compared with specifications in Eurocode 4 (EC4) and AASHTO LRFD bridge design specifications (AASHTO). The following results were obtained. The modeling agrees with the experiment. The critical steel height-to-slab thickness ratio is around 4. When the ratio deviates from the critical value, beff is reduced with the increase of slab thickness. ID has a slight influence on beff. beff changes within 10% when ID changes within 10%. The maximum beff can be obtained when the web spacing-to-physical width ratio is 1/2. The decrease of web spacing brings a maximum reduction of 14% on beff, whereas increasing web spacing results in a maximum reduction of 70% for twin I-beam. The coupled effect of web position and slab thickness is limited. The maximum difference is 25%. Recommended equations were proposed to evaluate beff for single I-beam and twin I-beam composite girders based on the specifications in EC4 and AASHTO, which can ensure that the negative error is within 10%.

Numerical and Experimental Behavior Analysis of Slabs Strengthened Using Steel Plates and Slurry-Infiltrated Mat Concrete (SIMCON) Laminates

This study has two main aims; firstly, investigating the behavior of slabs that are strengthened with different types of reinforcements and with Slurry-Infiltrated Mat Concrete (SIMCON) laminates, having different dimensions and thicknesses and subjected to static and dynamic (impact) loads. Secondly, the development of a non-linear finite element (FE) model to simulate the behavior of the tested slabs utilizing the ABAQUS/Standard package. The modeling of the NSC slabs strengthened with either SIMCON or steel plates involves using three-dimensional solid elements that are partially integrated with the modeling of concretes using the 8-node brick element (C3D8R). The results of the experimental and numerical investigations are compared to examine whether the slab modeling is sufficient. The comparison includes the element type, material characteristics, real constants, and convergence study. The predicted ultimate load-carrying capacity versus vertical deformation response is compared with the lab results that correspond with it, as obtained via the FE analysis of all tested slabs. In addition, the results of the FE analysis of slab specimens that are strengthened with steel plates were compared to the results of the ones strengthened using SIMCON laminates. The obtained results have led to a number of significant observations. Considering the punching shear strength, it was found that using SIMCON strengthening in different dimensions increased the slab’s punching shear capacity and outperformed steel-strengthened slabs. As for the plate stiffness, SIMCON-strengthened slabs presented higher stiffness rates than steel-strengthened slabs, to the extent that even 20 mm SIMCON strengthening outperformed the steel plate-strengthened slabs of any thickness or dimensions. The axial load-displacement relationships indicate that all the numerical models show a stiffer behavior when compared with the experimental axial load-displacement relationships. The slab thickness of SIMCON significantly affects the load-carrying capacity, and it increases with the increase in thickness. Likewise, using strengthening from steel plates gives a higher load-carrying capacity. Finally, since the results of the yield line analyses for these slabs are found to match the experimental results closely, this method is considered to be suitable for practical use in determining the strength of plated slabs. Therefore, the conclusion is drawn that the proposed FE model can be sufficiently used in evaluating the dynamic responses of slabs strengthened with SIMCON or steel plates and subjected to cyclic and impact load.
