Abstract:

Concrete filled double-steel-plate composite walls with shear studs, one type of steel–concrete–steel walls, are recently developed and have been used in high-rise buildings, for which fire safety is a big concern. In order to investigate the fire endurance of this new type of concrete filled double-steel-plate composite walls, three specimens with different axial compression ratios and different lengths and intervals of shear studs were tested under one-side ISO-834 standard fire to obtain the temperature distribution, deformation, and detailed failure modes. Each specimen consisted of a concrete filled double-steel-plate composite wall-body and two boundary columns. Moreover, finite-element-based numerical investigations were conducted to confirm and extend experimental findings. All the concrete filled double-steel-plate composite walls failed in compression–flexure mode with the local buckling at the compressive steel plate. The results indicate that the fire endurance of concrete filled double-steel-plate composite walls is significantly affected by the axial compression ratio, the eccentricity of the axial load, and the bond strength between shear studs and concrete. Axial compression ratio, defined as the ratio of axial compression to the nominal compressive capacity of concrete filled double-steel-plate composite walls, has both positive and negative effects on the fire endurance of concrete filled double-steel-plate composite walls. The axial load eccentricity toward the unexposed side is much more detrimental to the fire endurance of concrete filled double-steel-plate composite walls than the one toward the exposed side. In engineering practice, it is recommended that proper intervals (not greater than 300 mm) and lengths (not less than 40 mm) of the shear studs should be used to ensure the bond between concrete and steel plates.

Abstract:

Currently, terrorism attack is one of the main concerns in public safety, although the probability of such attack is fairly low. From the perspective of multi-hazard mitigation, it is expected that the structural members that are used to resist earthquakes or winds in buildings should also reduce the vulnerability to blast. Concrete filled double-steel-plate composite walls are one of the novel structural members which are used as shear walls, in which concrete is filled between two steel plates and connected to them through shear studs. In this article, finite-element-based analyses were carried out to investigate the dynamic behaviour of concrete filled double-steel-plate composite walls subjected to blast loading. A three-dimensional numerical model was developed and validated based on previously published experimental results. Then, the numerical models were employed to investigate the effects of axial compression ratio, concrete strength, wall thickness and shear connector spacing on the blast performance of concrete filled double-steel-plate composite walls under different blast intensities. The results show that axial compression has both positive and negative effects on the blast performance of concrete filled double-steel-plate composite walls. The positive effect prevails due to increased effective flexural stiffness when plastic deformation under zero axial compression and the same blast load is marginal, whereas the negative effect is more dominant due to P-delta effect when evident plastic deformation occurs under zero axial compression and the same blast load.

Abstract:

The shear wall with concrete filled steel tube (CFT) columns and steel plate is a new kind of composite shear wall. In order to know its seismic performance and failure mechanism, six 1/5 scale specimens with the same shear span ratio 1.5, including 3 steel plate shear walls (SPSWs) with CFT columns and 3 reinforced concrete shear walls (RCSWs) with CFT columns and embedded steel plate, were tested under cyclic loading. The thickness of the steel plates in the shear walls changed from 2mm, 4mm to 6mm. Based on the experiment, the load-carrying capacity, hysteresis characteristics, ductility, stiffness degradation, energy dissipation and damage characteristics of the specimens were analyzed. Especially, the ratio of height to sectional thickness of the steel plates in the shear wall was considered. The result shows that both the SPSW with CFT columns and the RCSW with CFT columns and embedded steel plate have good seismic performance and are with important practical engineering value.

Abstract:

In composite plate shear walls–concrete filled (C-PSW/CF), there is an indeterminate flow of force between concrete, steel plate and tie bars. Finite element methods (FEM) are frequently used to verify this force flow. The theoretical models available in the literature to predict the tie bar maximum axial force demands were based on walls without boundary plates. The finding in this study is intended to help understand whether current theoretical approaches are conservative and can be applied to boundary plate walls as well. Within the scope of this study, tie bar axial force demands for walls with boundary plates consisting of planar and round shapes and without boundary plates were investigated and compared. For this, a previously benchmarked finite element (FE) wall model was considered and configured to have no boundary plate and have planar and round boundary plates. FE models were analyzed under monotonic lateral displacement up to 4% drift ratio. Passive lateral pressures and transverse force variations on the planar and round boundary plates were investigated.

Abstract:

Based on the program of nuclear power engineering, the in-plane buckling behavior of Steel plates and concrete filled composite shear wall (SCSW) was investigated. 9 1/5 scaled specimens were conducted under horizontal cyclic load and constant vertical load. The parameters such as the space of studs, the vertical load, the form of connectors, and the thickness of the steel plate were designed to research the affection on the buckling of the steel plate. According to the results of tests, it can be seen that the bulge of the steel plate occurred at about 50mm above the top of the foundation beam. The bulge can be connected as a whole in the specimens with studs only, but not in the specimens with stiffeners. Finite element models were performed to simulate the buckling behavior of the steel plate, and the results were found to be in good agreement with the test results. The buckling stress of the steel plate was calculated by equations based on the measuring data. It was found that they were smaller than that of finite element analysis. The more accurate simulation was needed.

Abstract:

Cyclic lateral loading tests were conducted on six composite plate shear walls–concrete encased and two conventionally reinforced concrete walls. The composite plate shear walls–concrete encased were constructed using high-performance concrete and different steel configurations with a same steel content ratio. These walls were divided into two batches. Three composite plate shear walls–concrete encased and one conventional wall were first exposed to the ISO 834 standard fire before the cyclic tests. To their comparison, the other four walls were only tested under the cyclic loading at room temperature. During the fire tests, the four walls experienced the spalling of concrete. The composite plate shear walls–concrete encased suffered more explosive spalling than the conventional wall. After the fire tests, all walls were tested under the cyclic loading. Based on the test results, analysis and discussions were made on the lateral load, lateral stiffness, and energy dissipation ability of walls. The difference was identified between the behavior of composite plate shear walls–concrete encased and that of conventional wall. Moreover, the influences of fire exposure were analyzed on seismic behavior of shear walls. Generally, the high temperatures reduce the yield, peak, and ultimate loads of walls and degrade the lateral stiffness. No significant difference can be found in energy dissipation ability between the heated and unheated walls before the drift ratio 1/120.

Abstract:

This paper investigates the out-of-plane shear behavior of composite steel-plate-reinforced concrete walls (SC walls) and proposes their shear-strength-models based on plasticity theory limit analysis. For speedy, modular construction, SC walls are fabricated using double-skin steel plates with welded shear studs and sandwiching concrete between them. A review of current design formulas provides better understanding of bond-stress-dependent shear behavior relying on studs of SC walls. We conducted experiments on bondstrength-dependent arch and/or truss action to verify proposed shear-strength models with test results. Test results, including those from literature, agreed well with the strength anticipated by proposed formulas.

Abstract:

The steel-plate reinforced concrete shear wall with rectangular concrete filled steel tube (CFST) columns is a new kind of composite shear wall. In order to ascertain its seismic behavior and failure mechanism, four 1/5 scale specimens with the same shear span ratio 1.5, different thickness of the steel-plate and different axial force ratio, were tested under horizontal cyclic loading. The thickness of steel-plate in the walls is 2mm, 4mm, 4mm and 6mm, respectively. Based on the experiment, the load-bearing capacity, hysteretic characteristics, ductility, stiffness degradation, energy dissipation capacity and failure mode of the specimens were contrastively analyzed. And the effect of the ratio of height to sectional thickness of steel-plate and the value changes of axial force ratio on seismic behavior of the new shear wall was also analyzed. The result shows that the steel-plate reinforced concrete shear wall with rectangular CFST columns has good seismic performance and important engineering value.

Abstract:

Several experiments are conducted to investigate the seismic behavior of composite shear walls because of their advantages compared to traditional reinforced concrete (RC) walls. However, the numerical studies are limited due to the complexities for the steel and concrete behaviors and their interaction. This paper presents a numerical study of composite shear walls with stiffened steel plates and infilled concrete (CWSC) using ABAQUS. The mechanical mechanisms of the web plate and concrete are studied. FE models are used to conduct parametric analysis to study the law of parameters on the seismic behaviour. The finite element (FE) model shows good agreement with the test results, including the hysteresis curves, failure phenomenon, ultimate strength, initial stiffness, and ductility. The web plate and concrete are the main components to resist lateral force. The web plate is found to contribute between 55% and 85% of the lateral force of wall. The corner of web plate mainly resists the vertical force, and the rest of web plate resists shear force. The concrete is separated into several columns by stiffened plates, each of which is independent and resisted vertical force. The wall thickness, steel ratio, and shear span ratio have the greatest influence on ultimate bearing capacity and elastic stiffness. The shear span ratio and axial compression ratio have the greatest influence on ductility. The test and analytical results are used to propose formulas to evaluate the ultimate strength capacity and stiffness of the composite shear wall under cyclic loading. The formulas could well predict the ultimate strength capacity reported in the literature.

Abstract:

The structural element within the whole structure contains structural elements like beams, slabs, columns and reinforced concrete walls. One of the most vertical structural elements is shear wall that built to giving stability to the building, resisting lateral force such as earthquake and wind and to reduce the building deformations. In present study, the analysis of corrugated vertical steel plate shear walls using finite element method by ABAQUS software is examined. Four different modes are analysed in which the first model is vertical corrugated steel shear wall plate, second is the composite shear wall with full interaction, third is the composite shear wall and finally the fourth model is composite shear wall with gap between concrete panel and steel frame to check out the full performance of different shear wall under the effects of cyclic loadings. Displacement, drift and energy dissipation will investigate throughout analysis. Analysis results indicated that the gap and composite action between steel and concrete panel play an important role on the performance of shear wall under cyclic loading. The decrease in displacement of composite shear wall as compared with the steel shear wall reach 11.86%.

Abstract:

Composite shear walls are widely used in high-rise buildings because of their high bearing capacity. To improve the bearing capacity of ordinary shear walls, restraining elements are usually installed at both boundaries or within the wall body. In this article, two different restraining elements, namely, a rectangular steel tube and a column-type reinforcement (the whole wall body was restrained by segmented stirrups and tied by diagonal bars), were applied to the boundary frame and wall body of the shear wall either jointly or separately. A new type of steel-concrete composite shear wall, referred to as a composite shear wall incorporating a concrete-filled steel tube boundary and column-type reinforced wall, was proposed. In addition, three specimens with different restraining elements, namely, a column-type reinforced shear wall, a concrete-filled steel tube boundary shear wall and an ordinary reinforced concrete shear wall, were presented for comparison. The influences of the two different restraining elements on the seismic performance and bearing capacity of the shear walls were analyzed from four perspectives of failure mode, hysteresis behavior, stiffness and residual deformation, and the equivalent lateral pressures of the two restraining elements were calculated. Based on the plane-section assumption, expressions for the crack, yield, peak and ultimate bearing capacities were derived, and the effects of the two restraining elements on the peak and ultimate bearing capacities were considered. The results show that these two restraining elements significantly improved the bearing capacity of the shear wall specimens, and the concrete-filled steel tube restraining element was more effective than the column-type reinforced restraining element. Finally, the calculated values of the bearing capacity of the four different restraining elements of the shear wall specimens proposed in this article were in good agreement with the experimental values.

Abstract:

Shear walls are effective lateral load resisting elements in high-rise buildings. This paper presents an experimental study of the seismic performance of a composite shear wall system that consists of high-strength concrete walls with the embedded steel plate. Two sets of wall specimens with different aspect ratios (height/width, 1.5 and 2.7) were constructed and tested under quasi-static reversed cyclic loading, including five reinforced concrete shear walls (RCSW) and six reinforced concrete-steel plate shear walls (RCSPSW). The progression of damage, failure modes, and load-displacement responses of test specimens were studied and compared based on experimental observations. The test results indicated that high-strength (HS) RCSPSW system showed superior lateral load strength and acceptable deformation capability. The axial compressive load was found to have an indispensable effect on the ductility of both RCSW and RCSPSW, and an upper limit of axial compression ratio (0.5) is recommended for the application of HS RCSPSW in engineering practices. In addition, the design strength models were suggested for predicting the shear and flexure peak strength values of RCSPSW systems, and their applicability and reliability were verified by comparing with test results.

Abstract:

In this paper, the influence of design parameters on the strength of steel–concrete composite shear walls is investigated by means of finite element (FE) simulations. The shear wall typology studied in this paper consists of multiple composite plate shear wall-concrete encased on one or both sides of the plates. The FE models include contact technology to capture debonding between concrete and steel, tensile cracking in concrete, and large deflection theory involving local instabilities. Some design parameters considered in this work are the height-to-width ratio of the steel plates and their thickness, number of steel plates, the cross-section of the columns, and the height-to-width ratio of the shear wall. Furthermore, a sensitivity analysis of the normalised shear strength per unit cost of structure for these design parameters is also studied. Our numerical predictions are validated successfully with experimental data reported in the literature, revealing the predictive capabilities of the model. The present results provide further insight into the structural behavior of steel–concrete composite shear walls and pave the way for the future development of more efficient and innovative steel–concrete composite systems.

Abstract:

In recent years, steel-concrete composite shear walls have been widely used in enormous high-rise buildings. Due to their high strength and ductility, enhanced stiffness, stable cycle characteristics and large energy absorption, such walls can be adopted in auxiliary buildings, surrounding the reactor containment structure of nuclear power plants to resist lateral forces induced by heavy winds and severe earthquakes. The current study aims to investigate the seismic behaviour of composite shear walls and evaluate their performance in comparison with traditional reinforced concrete (RC) walls when subjected to cyclic loading. A three-dimensional finite element model is developed using ANSYS by emphasising constitutive material modelling and element type to represent the real physical behaviour of complex shear wall structures. The analysis escalates with parametric variation in reinforcement ratio, compressive strength of the concrete wall, layout of shear stud and yield stress of infill steel plate. The modelling details of structural components, contact conditions between steel and concrete, associated boundary conditions and constitutive relationships for the cyclic loading are explained. The findings of this study showed that an up to 3.5% increase in the reinforcement ratio enhanced the ductility and energy absorption with a ratio of 37% and 38%, respectively. Moreover, increasing the concrete strength up to 55 MPa enhanced the ductility and energy absorption with ratios of 51% and 38%, respectively. Thus, this improves the contribution of concrete strength, while increasing the yield stress of steel plate (to 380 MPa) enhanced the ductility (by a ratio of 66%) compared with the reference model. The present numerical research shows that the compressive strength of the concrete wall, reinforcement ratio, layout of shear stud and yield stress of infill steel plate significantly affect ductility and energy absorption. Moreover, this offers a possibility for improving the shear wall’s capacity, which is more important.

Abstract:

The composite shear wall has various merits over the traditional reinforced concrete walls. Thus, several experimental studies have been reported in the literature in order to study the seismic behavior of composite shear walls. However, few numerical investigations were found in the previous literature because of difficulties in the interaction behavior of steel and concrete. This study aimed to present a numerical analysis of smart composite shear walls, which use an infilled steel plate and concrete. The study was carried out using the ANSYS software. The mechanical mechanisms between the web plate and concrete were investigated thoroughly. The results obtained from the finite element (FE) analysis show excellent agreement with the experimental test results in terms of the hysteresis curves, failure behavior, ultimate strength, initial stiffness, and ductility. The present numerical investigations were focused on the effects of the gap, thickness of infill steel plate, thickness of the concrete wall, and distance between shear studs on the composite steel plate shear wall (CSPSW) behavior. The results indicate that increasing the gap between steel plate and concrete wall from 0 mm to 40 mm improved the stiffness by 18% as compared to the reference model, which led to delay failures of this model. Expanding the infill steel plate thickness to 12 mm enhanced the stiffness and energy absorption with a ratio of 95% and 58%, respectively. This resulted in a gradual drop in the strength capacity of this model. Meanwhile, increasing concrete wall thickness to 150 mm enhanced the ductility and energy absorption with a ratio of 52% and 32%, respectively, which led to restricting the model and reduced lateral offset. Changing the distance between shear studs from 20% to 25% enhanced the ductility and energy absorption by about 66% and 32%, respectively.

Abstract:

In order to strengthen the co-work performance between the steel plate and concrete, the anchorage construction of arrayed studs were welded on both sides of the plate according to a super high-rise building in Beijing. Eighteen specimens of embedded steel plate concrete shear walls with arrayed studs were tested by pushing out under monotonic loading in this paper. Some parameters, such as the thickness of the concrete wall, the thickness of steel plate, the diameter, the length and the amount of the studs and the rate of reinforcement for distributing bars in the walls were considered. The shear bearing capacity, load-slip relationship, strains of the steel plate and studs, mechanical properties and failure mode were analyzed. The effect of stud layout on the coordinate work of the concrete plate was studied. Results show that the shear bearing capacity is obviously improved by using smaller diameter studs or decreasing the distance between studs when the total area of studs is kept unchanged. The thickness of the steel plate has almost no effect on the shear bearing capacity. The ratio of the length to the diameter of the studs should be not less than 4. A simplified mechanics calculated method to estimate the shear bearing capacity of this kind of shear wall was put forward. And the calculated results are in good agreement with the experimental results.

Abstract:

In order to study the seismic performance of low shear-span ratio composite shear wall with steel plate reinforced concrete,three low shear-span ratio composite shear walls with steel plate reinforced concrete were tested.The deformation performance and failure modes were observed under low cyclic lateral loads with high axial compression ratio.Valuable results were obtained for the hysteretic curves,skeleton curves,ductility and energy dissipation capacity.The results indicate that the elastic stage, Specimen stiffness value is larger, and the stiffness change is basically the same; The specimen into the elastic-plastic stage, cracks have appeared in basic beam and early damage. The junction of steel concrete structure and reinforced concrete structure are prone to failure, which should improve the reinforced concrete shear stiffness in the design.

Abstract:

This research is presented experimental and numerical investigations of composite concrete-steel plate shear walls under axial loads to predicate the effect of both concrete compressive strength and aspect ratio of the wall on the axial capacity, lateral displacement and axial shortening of the walls. The experimental program includes casting and testing two groups of walls with various aspect ratios. The first group with aspect ratio H/L=1.667 and the second group with aspect ratio H/L=2. Each group consists of three composite concrete -steel plate wall with three targets of cube compressive strength of values 39, 54.75 and 63.3 MPa. The tests result obtained that the increase in concrete compressive strength results in increasing the ultimate axial load capacity of the wall. Thus, the failure load, the corresponding lateral displacement and the axial shortening increased by increasing the compressive strength and the rate of increase in failure load of the tested walls was about (34.5% , 23.1%) as compressive strength increased from 39 to 63.3 MPa for case of composite wall with aspect ratio H/L=1.667 and H/L=2, respectively. The effect of increasing aspect ratio on the axial load capacity, lateral displacement and axial shortening of the walls was also studied in this study. Compared the main performance characteristic of the testing walls, it can be indicated that the walls with aspect ratio equal to (2) failed under lower axial loads as compared with walls with aspect ratio equal to 1.667 ratios by about (5.8, 12, 15.6 %) at compressive strength (39, 54.75, 63.3 MPa), respectively and experienced large flexural deformations. The mode of failure of all walls was characterized by buckling of steel plates as well as cracking and crushing of concrete in the most compressive zone. Nonlinear three-dimensional finite element analysis is also used to evaluate the performance of the composite wall, by using ABAQUS computer Program (version 6.13). Finite element results were compared with experimental results. The comparison shows good accuracy.

Abstract:

It is apparent from a review of the literature and current research related to the design of ice-resisting walls for offshore structures that there is a need for more efficient designs of these structural elements. The object of this study was to examine an alternate structural element for ice-resisting walls, a flexible composite plate system, which is simple in detail, design, and construction and utilizes the capacity of the section.An exploratory experimental program was undertaken to determine the strength and behaviour of flexible steel–concrete composite sandwich plates, without mechanical shear interconnectors, subject to transverse loads. A series of six composite plate elements, continuous over supporting composite bulkheads and axially restrained, were tested with a four-point load system. The primary variables investigated were plate thickness, which varied from 3.18 to 6.35 mm, and section depth which gave span-to-depth ratios from 15 to 25.Three regions of behaviour of the composite plates were observed: flexural, flexural membrane, and membrane. The flexural capacity is limited by the development of a plastic mechanism, and the ultimate capacity is limited by the tensile–shear strength of the double membrane steel plates. The average maximum centre-span deflection at failure exceeded one-sixth of the span. The characteristics of the flexible composite plates make it a favourable alternative to conventional and semi-rigid composite plate construction. Key words: composite, concrete, ductility, energy absorption, flexible, flexural behaviour, membrane behaviour, plates, steel.

Abstract:

RC shear wall with STRC (steel tube-reinforced concrete) columns and embedded steel plate has been proposed and used in the project of an International Conference Center. In order to ascertain the seismic performance of this kind of composite shear walls with different openings in the practical engineering, four 1/7 scale specimens with shear span ration 2.0 were tested under low-frequency cyclic loading. The load-carrying capacity, ductility, stiffness and its attenuation, hysteretic property, energy dissipation capacity and failure mode of the specimens were analyzed. The effect of the embedded steel plate and the concealed steel trusses on the seismic performance of the walls was studied. The results show that the ductility and load-carrying capacity of RC shear wall are improved greatly by setting the embedded steel plate or concealed steel trusses in the wall; The embedded steel plate and the concrete work very well through the stud connectors welded on the steel plate and the tie bars inserted in the walls; The STRC columns have the advantage of higher load-carrying capacity, not easy to crack and better ductility; The new composite shear wall has good seismic performance and important practical value. It is suitable for large and complex application of high-rise buildings in the seismic regions.

Abstract:

Composite shear wall is a structural component consisting of a steel plate connected using shear tabs to a reinforced concrete cover. The steel plate provides for stiffness, strength, and ductility and the concrete cover prevents the steel plate from buckling. In this paper, effects of steel plate's thickness, compressive strength and thickness of the concrete cover and spacing of the shear tabs on the characteristics of the wall in nonlinear lateral behaviour are evaluated and a macromodel substitute for the wall is developed. The macromodel is a generic lateral force-displacement rule for the wall with its characteristics as developed in this paper. Practical ranges of values are accounted for the parameters involved. Such an approach makes it possible to replace the very complicated and time-consuming three-dimensional model of the composite wall with a simple one-dimensional element following the nonlinear lateral force-displacement path as given in this paper.

Abstract:

An innovative double steel concrete (DSC) composite wall was developed to enhance constructability and lateral load resistance of buildings. Three low-aspect ratio DSC composite walls were constructed and tested to study the shear behavior. Under different testing parameters, the failure modes, hysteresis behavior, lateral load resisting capacity, deformation, and energy dissipation of the composite walls were observed. The results showed that all specimens failed in shear behavior with steel plate buckling and concrete compressive crushing. The pinching behavior was obvious for hysteresis loops of composite walls. Moreover, the lateral load resisting capacity and deformation were significantly affected with axial compression ratio and steel ratio. Beyond that, the ductility coefficients of specimens reached 3.30. The finite element (FE) method was performed to analyze the failure process of the specimens with cyclic analysis. The concrete damage plastic model (CPDM) was selected to simulate the damage progress of concrete. Validation of the FE models against the experimental results showed good agreement.

Abstract:

Steel-Concrete composite shear wall has become popular recently as it compensates for the disadvantages of concrete and steel plate shear walls and combine the advantage of both. However, there is no detail study that identifies the most critical parameters. This study aims at investigation of steel plate-concrete composite shear wall behavior under cyclic loading with variables such as concrete strength, grade of steel plate, total number of tie constraints and thickness of steel plate. ABAQUS/Standard is used for numerical modeling in this study. As the concrete strength decreases from 86.1Mpa to 45Mpa, the load capacity declined by 11.76% and higher stiffness was recorded in specimen with higher grade of concrete. The ductility factor is inversely proportional to grade of concrete from 86.1Mpa to 60Mpa which increases from 4.26 to 4.68 and the ductility factor of specimen with 45Mpa strength is recorded as 3.81. The energy dissipation capacity is directly proportional to the grade of concrete used. Using high grade steel plate increases the lateral load capacity significantly and exhibited more ductile behavior. Specimen with S355 steel grade exhibited 14.01% increment of the average load capacity while the specimen with S245 steel grade has shown reduction by 9.21%. Similarly, the ductility factor and energy dissipation capacity of specimen with variable grade of steel are directly proportional. Reduction of tie constraints has no significant effect on the behavior in this study due to high confinement effect of concrete by surrounding steel plate. Specimens with thicker steel plate exhibited good energy dissipation capacity.

Abstract:

The steel plate reinforced concrete shear wall (abbreviated as SPRCW) is an innovative type of lateral force resisting structural member potentially used in steel-concrete composite structures, especially in high-rise buildings. This paper presents an experimental study on seismic behavior of such kind of shear walls. The test specimens include five SPRCW models and one ordinary specimen RCW-1 built at the aspect ratio is 2. The combination of the following wall parameters is varied: thickness of the steel plate, thickness of the SPRCW, axial compression ratio, and detailing such as lateral ties cross the steel plate. The experimental program is developed to evaluate the damage patterns, hysteretic response, strength, stiffness and ductility behavior of the walls under axial compressive loads and cyclic horizontal forces. In addition, the experimental results are analyzed in comparison with those of anthoer ordinary RC shear walls. The investigation shows that this type of shear wall has the potential to offer strength adequate for resisting forces from earthquake and stiffness appropriate for limiting drift for tall buildings with less size than ordinary RC walls. It is also observed that steel plate encased in the wall plays a major role in bearing loads, while concrete provides lateral restraint for steel plate, and hence increasing global stability and deformation capacity of the wall.

In this paper, 2 bay single-layer single-span hollow fly ash plate sandwich polyurethane in filled frames were tested under low cyclic horizontal loadings with different ratio of high to width and different stiffness frame . Based on the experiment, the damage process, failure mode, load carrying capacity are studied. The interaction between the fly ash plate sandwich polyurethane infill walls and the overall frame of constraint system are investigated. The results indicate that the bearing capacity has little related to height-width ratio of wall; sandwich polyurethane wall panels and frame has good integrity and energy dissipation capacity; the ratio of high to width smaller, ductility of wall is better . After study the failure pattern of the specimen, we know that the bearing capacity of fly ash powder polyurethane thermal insulation wall is not accord with formula of seismic shear of not bearing masonry.

Abstract:

The coupled steel plate and reinforced concrete (C-SPRC) composite wall is a new type of coupled-wall system consisting of steel coupling beams (SCBs) that join two SPRC walls where the steel plate shear wall (SPSW) is embedded in the RC wall. Although the C-SPRC wall has been extensively constructed in high-rise buildings in seismic regions, research on its behavior has rarely been reported. No code provisions are available for directly guiding the preliminary design of such coupled-wall systems. In the research, three 1/3-scaled C-SPRC wall subassemblies including one-and-a-half stories of SPRC walls and a half-span of SCB were tested under simulated earthquake action, considering the fabrication method of the embedded SPSW and the shear-span ratio of the SPRC walls as two test variables. The prime concern of the research was to evaluate the influences of those popular design and construction parameters on the seismic behavior of the C-SPRC wall. Deviating from the beam tip loading method used in conventional subassembly tests, the lateral cyclic load in this research was applied at the top of the wall pier so that the behaviors of both walls and SCBs could be examined. The test results exhibited the great seismic performance of the subassemblies with the coupling mechanism fully developed. The energy dissipation capacity and inter-story deformation capacity of the subassembly with the assembled SPSW were roughly 9.4% and 13.2% greater than those with the conventional welded SPSW. Compared with the subassembly with the shear-span ratio of 2.2, the interstory-deformation capacity of the one with the shear-span ratio of 2.0 was increased by approximately 13.4%, while the energy dissipation capacity was decreased by 10.9%. The test results were further compared with the simulation results using the proven-reliable finite element analysis with respect to the hysteretic curves, skeleton curves, energy dissipation capacities and failure patterns.

Abstract:

The safety and cost of structures composed of concrete-filled steel tube (CFST) frame-steel plate shear walls (SPSWs) with two-side connections are governed by the seismic performance. The response modification factor R and displacement amplification factor Cd are important seismic performance factors. In this paper, nonlinear seismic responses of 10-story, 15-story, and 20-story CFST frame-SPSWs (CFST-SPSWs) are studied. A nonlinear finite element model which includes both material and geometric nonlinearities is developed using the finite element software OpenSees for this study. The accuracy of model was validated by comparing with experimental results. Nonlinear seismic analysis shows that CFST-SPSWs, in high seismic region, behave in a stable and ductile manner. Also, R and Cd of CFST-SPSWs were evaluated for the structure models using incremental dynamic analysis (IDA), and the average values of 3.17 and 3.05 are recommended, respectively. The recommended R value is greater than the value (2.8) in the “Chinese Code for seismic design of buildings” for composite structures, indicating the code is conservative. The structural periods provided by current code are generally lower than the periods calculated by finite element analysis. Research results show that R and Cd increase with increasing story number, span number, and structural period. Ductility reduction factor Rμ increases with increasing span number and decreasing story number. Overstrength factor Rs increases with increasing story number and decreasing span number.

Abstract:

An assembling method of precast shear walls was previously proposed using steel–concrete composite bolted connectors. To further investigate the effectiveness and mechanical behavior of the proposed composite connector, 11 specimens were fabricated and tested under monotonic tensile loading. The test results provided comprehensive data (e.g. load, deformation, failure mode) on the effects of variation in the thickness of steel cap plate, concrete strength, bolt tension, and bolt diameter. Two typical failure modes were observed in the test: bearing failure and bolt shear failure. Finally, the equations for calculating the ultimate strength and yield strength of steel–concrete composite bolted connector are proposed in this article by reference to those of conventional bolted connection. The proposed calculations are demonstrated to be accurate enough through verification with the experimental data.
