Abstract:

The purpose of this study is to understand the fundamental resistance mechanism and the shear strength of the frame with the reinforced concrete infill wall by comparing analytical with experimental results. For this, one-story and one-bay four specimens were manufactured with variables; Lightly Reinforced Concrete Frame (LRCF), monolith placing Shear Wall (SW), CIP Infill Wall (CIW-1) and CIP Infill Wall reinforced with diagonal rebar (CIW-2). The addition of the RC infill wall was significantly improved the strength and the stiffness. Compared with specimen LRCF, ultimate strength and initial stiffness of infills was improved 4 and 6 times, respectively. The case of specimen CIW-2, structural performance was improved remarkably by placing a diagonal rebar.

Abstract:

The test process and analysis of 3 walls and the expand calculation about walls are introduced in this paper. Through a series of low-cycle repeated load experiments, the paper do comparative studies on the seismic behavior of concrete shear wall and brick wall strengthened with reinforced concrete splint firstly. Because of the limitations of experiment, the study focuses on the unreinforced brick wall, the 120mm shear wall, the brick wall strengthened with double 60mm reinforced concrete splint and the brick wall strengthened with single 60mm reinforced concrete splint. On the basis of the experiment, we use the finite element software to establish a rational numerical model. Through the finite element analysis, the paper expands the calculation about walls and makes up for the lack of experimental research. Based on the analysis results, we get the conclusion that the reinforced concrete splint can enhance the seismic behavior of the unreinforced brick wall. Taking no consideration of structures’ integral stability, the seismic behavior of brick wall strengthened with double 60mm reinforced concrete splint is equivalent to the 120mm shear wall.

Abstract:

For engineering practice purpose, the macroscopic model capable of simulating the main characteristics of nonlinear behavior is desirable to reduce computational efforts in nonlinear structural analysis. Several different types of macroscopic models for shear walls have been developed. The shear wall element used in the commercial program PERFORM-3D is one types of macroscopic models for reinforced concrete shear walls. The application of PERFORM-3D in the nonlinear static analysis of reinforced concrete shear walls is introduced in this study. The selection of constitutive models and the determination of related parameters of the constituent material are presented in detail. The applicability of the shear wall element is verified by numerical simulation on three reinforced concrete shear wall specimens under cyclic loading. The comparison between the numerical analysis and test results leads to the conclusion that the shear wall element with appropriate constitutive models can capture the nonlinear behavior of reinforced concrete shear wall well and be conveniently applied in engineering practice.

Abstract:

This study was conducted to experimentally investigate the shear behavior of non-ductile squat shear walls with different cement matrixes such as normal concrete, fiber-reinforced concrete(FRC), and strain-hardening cement composite(SHCC). The cement matrix type’s effect in the lightly reinforced squat shear wall was evaluated through the testing of three one-third scale walls with a height-to-length ratio (hw/lw) of 0.55 under top displacement reversals. Experimental results show that the cement matrix type in the non-seismically detailed squat shear walls has a significant effect on the shear behavior and failure mode. Compared to reinforced FRC and SHCC shear walls, reinforced concrete wall exhibited brittle behavior. Reinforcing fibers in the FRC and SHCC mitigated the crack damage of wall and increase the shear strength.

Abstract:

This study proposes a new type of shear wall, namely, the concrete-filled steel tube composite shear wall, for high performance seismic force resisting structures. In order to study the seismic behavior of concrete-filled steel tube composite shear wall, cyclic loading tests were conducted on three full-scale specimens. One conventional reinforced concrete shear wall was included in the testing program for comparison purpose. Regarding the seismic performance of the shear walls, the failure mode, deformation capacity, bearing capacity, ductility, hysteretic characteristics, and energy dissipation are key parameters in the analysis procedure. The testing results indicated that the bearing capacity, the ductility, and the energy dissipation of the concrete-filled steel tube composite shear walls are greater than that of conventional reinforced concrete shear walls. In addition, the influence of axial compression ratio on the seismic behavior of concrete-filled steel tube composite shear wall is also investigated. It was found that higher axial compression ratio leads to an increase in the bearing capacity of concrete-filled steel tube composite shear walls while a reduction in the ductility capacity.

Abstract:

Although shear walls are a widely used system for providing lateral load resistance, nonlinear analysis procedures for this type of element are much less well developed than those for frame and truss elements. Equivalent flexural models do not include shear deformation and are only suited for symmetric, straight walls. This paper describes the development of an analysis model which includes nonlinear effects for both shear and flexure. The formulation is based on a "macro" modelling approach which is suitable for complete building models in a design office environment. An analysis methodology is developed using engineering mechanics and experimental results and implemented in an existing nonlinear analysis computer program. A model is developed and validated against test results of solid walls and walls with openings. This shows that the model can capture the general characteristics of hysteretic response and the maximum strength of the wall. Results can be evaluated using acceptance criteria derived from published guidelines. An example shear wall building is then evaluated using both the nonlinear static and the nonlinear dynamic procedures. The procedure is shown to be a practical method for implementing performance based design procedures for shear wall buildings.

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:

In order to improve the seismic performance of common concrete shear wall with concealed bracings, fiber reinforced polymer modified concrete instead of ordinary concrete was applied to the shear wall as described in this paper. In this paper, the experimental study on the seismic performance of two different types of shear walls under cyclic loading was carried out, and also the failure characteristics, bearing capacity, ductility, hysteretic curve, stiffness attenuation and energy dissipation performance of the proposed shear wall were analyzed systematically. The test results show that the seismic performance of fiber-reinforced polymer modified concrete shear wall is significantly improved because its the damping ratio, deformation capacity and energy dissipation capacity are greatly improved compared with ordinary concrete shear wall with concealed bracings, which ensures its better stiffness stability in the later stage.

Abstract:

It is necessary to study failure dependence problem in order to solve system reliability in the field of Civil Engineering. In this paper, failure dependence of reinforced concrete shear walls with different openings (including the whole shear wall, the shear wall with small opening, the coupled shear wall, the shear wall frame) are studied under fortification earthquakes using Monte Carlo method. The results demonstrate that failure of reinforced concrete shear walls with different openings is neither fully independent nor fully relevant. The number of failure dependent floors is about one-half total floors. The failure dependent floors are concentrated mainly in the upper part.

In order to discuss the effect of different concrete strength on the seismic behavior of the L-shape steel reinforced concrete (SRC) short-pier shear wall , this article analyze three L-shape steel reinforced concrete short-pier shear walls of different concrete strength with the numerical simulation software ABAQUS, revealing the effects of concrete strength on the walls seismic behavior. The results of the study show that the concrete strength obviously influence the seismic performance. With the concrete strength grade rise, the bearing capacity of the shear wall becomes large, the ductility becomes low, the pinch shrinkage effect of the hysteresis loop becomes more obvious.

Abstract:

This article investigates the shear strength of steel plate reinforced concrete shear wall under cyclic loads. A nonlinear three-dimensional finite element model in ABAQUS was developed and validated against published experimental results. Then, a parametric study was conducted to evaluate the effects of the parameters on the lateral capacity of composite shear wall, including shear span ratio, concrete strength, axial load ratio, steel plate ratio and transverse reinforcement ratio of the web. Furthermore, a modified formula of shear strength of composite shear wall was proposed. Regression analyses were used to obtain the contribution coefficients of different parts from 720 finite element models. Finally, the shear strengths of specimens from published tests were compared with design strengths calculated using the proposed formula, American Institute of Steel Construction Provisions and Chinese Code. It was found that the Chinese Code well predicts the shear strength of composite shear wall of a steel plate ratio of less than 5%, while unsafely predicting that of a higher steel plate ratio. The American Institute of Steel Construction Provisions predictions are quite conservative because the contribution of the reinforced concrete is neglected. The modified formula safely predicts the shear strength of composite shear wall.

Steel plate reinforced concrete (SPRC) shear wall consists of steel plate encased in the concrete, in which the material advantages of both concrete and steel are utilized. The lateral resistance and deformation capacity of the shear wall are greatly improved. This paper investigates the deformation capacity of the SPRC shear wall under cyclic loads. A nonlinear 3-D finite element model in ABAQUS was developed and validated against published experimental results. Then, a parametric study was conducted to obtain the yield and ultimate rotation of SPRC shear walls with flexural failure. By statistical analyses, formulas for the yield and ultimate rotation of SPRC shear wall were proposed.

Selection about model reinforced concrete block masonry materials is presented when simple similar model is adopted in testing. Correlations between model and prototype results in basic strength characteristics of masonry prism are reported based on theory analysis. This includes axial compression, joint shear for ungrouted prisms and grouted prisms.

Abstract:

Precast two-way hollow slab concrete shear wall is a new structure adapted to housing industrialization. To study the effect of the vertical joint on mechanical behaviors of shear walls, one reinforced concrete shear wall and two precast concrete shear walls built with hollow slabs were quasi-statically tested under low cyclic loading. The study of failure mode and failure process of specimens shows that vertical macro-cracks occurred in precast walls under loading, which made failure behavior of walls evolve from integral wall into split wall. It also shows that relative deformation formed along the vertical joint before peak load, so the ductility of walls is increased. New type shear walls exhibit good ductility and brittle shear failure can be avoided effectively.

Abstract:

Shear walls are commonly used as structural elements to resist earthquake. The seismic performance of shear wall can be guaranteed under small earthquakes, but problems exist when it is subjected to large earthquakes. To improve the ductility and energy dissipation capacity of shear walls in large earthquakes, shear failure must be avoided and the performance of plastic hinge region must be improved. The adaptive-slit shear walls (ASSW) is proposed in this paper The mechanical characteristics of ASSW satisfy the requirements of structures under different seismic level. Therefore the damage process of ASSW can be controlled and the ductile shear failure can be realized, which obviously improve the seismic performance of shear wall structures.

Abstract:

In developing numerical approaches for predicting the response of reinforced concrete structures impacted on by deformable projectiles, we predict structural behavior collapse and damage using simple analysis and extensive nonlinear finite element (FE)models. To verify their accuracy, we compared numerical results to experimental data and observations on impact-loaded concrete walls with bending and transverse shear reinforcement. Different models prove adequate for different cases and are sensitive to different variables, making it important to rely on more than a single model alone. For wall deformation in bending mode, deflection is predicted reasonably well by simple four-node shell elements. Where punching dominates, transverse shear behavior must be considered. Formation of a shear failure cone is modeled using three-dimensional solid elements.

Abstract:

Precast concrete sandwich panels (PCSP) are often used as exterior cladding of residential buildings due to thermal efficiency. PCSP systems consist of two precast reinforced concrete walls separated by a layer of insulation and connected with connectors which penetrate the insulation layer and are anchored at two precast walls. This paper provides the pull-out test results of concrete sandwich panel (CSP) with non-shear connectors. The variables in this study were the casting direction of reinforced concrete walls and types of insulation. Test results indicated that the types of insulations and casting direction have a significant effect on the bond strength between concrete wall and insulation. The effect of insulation type is notable for CSP cast horizontally concrete walls.

This paper studies the influences of factors such as axial compressive ratio and shear wall thickness on the mechanical performance of the reinforced concrete column strengthening with shear wall under low-cyclic reversed loading. Considering the secondary stress characteristics of the strengthening column, a numerical analysis was made on the load displacement hysteretic curve and skeleton curve. The results show that, with the increasing of axial compression ratio, the bearing capacity and stiffness of reinforced concrete column increased, but the ductility of reinforced column reduced; the bearing capacity and rigidity of reinforced column strengthening with shear wall increase while the ductile was lower; the change of shear wall thickness has a little effect on the bearing capacity, but improves the energy dissipation capacity of reinforced concrete columns.

Abstract:

The basal theory of energy method is introduced, which makes use of the idea of energy balance to study the earthquake response of structures. Because of the high stiffness and low-cost of the steel frame-reinforced concrete shear wall hybrid structure, it is being widely used. But the study of the earthquake response prediction method of the structure has not been done yet. In this paper, energy method is used to study the earthquake response of the steel frame-reinforced concrete shear wall hybrid structure. A steel frame structure and a steel frame-reinforced concrete shear wall hybrid structure have been designed. The shear wall in steel frame-reinforced concrete shear wall hybrid structure is simplified as a column for easier study. In order to evaluate the results of the energy method, the time history analysis method is also used to study the earthquake response of the two structures. The shear coefficient, maximal interlaminar displacement and damage ratio of the two structures are studied. After comparison, it is found that the results of energy method and the time history analysis method are almost the same. The energy method can be easily used to study the earthquake response of the steel frame-reinforced concrete shear wall hybrid structure.

Abstract:

Three 1/3-scale squat steel fiber reinforced concrete (SFRC) shear walls with height-to-length ratio of 0.55 were manufactured and tested up to failure. Two walls (SFRC-SS and-LS) are similar to each other except the height (230 and 460mm) of vertical slits with the width of 40mm. For comparison, solid wall (SFRC-NS) was made. All specimens had the same rectangular cross-section of 1,100mm x 50mm, with wall panel height of 600mm. The experimental results showed that squat SFRC shear walls with vertical slits exhibited more stable hysteretic behavior than a solid SFRC shear wall. Vertical slits on the squat SFRC shear walls improve the ductility and energy dissipation capacity but decrease the load-carrying capacity and stiffness of squat SFRC walls.

Abstract:

Reinforced concrete (RC) structures have their own weight, earthquake, wind, dead loads, live loads, creep, etc. throughout their service life. They are exposed to internal and external load effects. In order to meet the horizontal forces such as earthquake and wind from these loads affecting the structure, shear wall structures with high lateral rigidity are needed. Therefore, shear walls are one of the most important structural elements that can resist earthquake forces due to their high lateral rigidity and load bearing capacities. Most of the buildings today are designed according to the old regulations. Therefore, the shear wall was sized and reinforced according to these old regulations. However, to date, standards have been renewed in certain periods. Despite this, shear walls designed according to the old regulations continue to resist seismic forces. In this study, the design and behavioral differences of the reinforced concrete shear walls between the Turkish Regulation that came into force in 2019, and the old regulation were compared. In addition, RC shear walls were evaluated according to ACI-318-19 and EuroCode-2 regulations.

Abstract:

A large number of reinforced concrete (RC) buildings constructed in the 1970s, whose main structural form is fish-bone shear wall, are still used in Qiansanmen area of Beijing. Due to the economical and technical limitation at the time, both the concrete strength and reinforcement ratio are far from satisfying the requirements given in the current seismic design code for concrete structures. In order to investigate the seismic performances of the wall with the low concrete strength and reinforcement ratio, four RC shear wall specimens were constructed and tested. Quasi-static tests considering large axial compression ratio were carried out, and the stiffness, the strength and the energy dissipation capacity of the RC shear walls are investigated. Test results suggest that the wall with low concrete strength and reinforcement ratio has low strength and poor deformation capacity, indicating the necessity of strengthening.

Abstract:

Abstract The composite wall with encased steel braces (ESB wall) is a novel type of steel–concrete composite wall that consists of a steel braced frame embedded in reinforced concrete. This arrangement is supposed to enhance the seismic performance of the wall, as the steel columns encased in the boundary elements can increase the flexural strength of the wall and the steel braces encased in the web can increase the shear strength. ESB walls have seen use in super tall building structures constructed in regions of high seismicity. The ESB walls are commonly used on stories where the shear force demand is very high. Currently, no design guidelines exist for the design of ESB Walls in the Eurocode. More research is required before a distinct set of guidelines can be prescribed for the design of ESB Walls. The present research will investigate behavior of composite walls with encased steel braces (ESB walls). Time history analysis will be performed to examine the shear strength and stiffness of the ESB walls. In this study, two frames with three floors and five floors will be modeled in ABAQUS software. Then the X- shaped braces and inverted V brace is added to frames. Later, reinforced concrete shear wall will be added to braced frames, so the steel braces encased in the reinforced concrete shear wall. Time history analysis, on the braced frames will be done Compare and note with each other. The results of the study are in good agreement with those of previous studies. However, none of these studies examined the effect of using V- and X-shaped struts and shear walls simultaneously, nor did they examine which struts reinforce the structures more strongly against earthquake vibrations. This has led the study to examine the effect of these reinforcements under various earthquakes. In future studies, reinforced concrete structures can also be used in addition to steel structures, and the results can be compared. In addition, these braces can also be used in other parts of the building. To meet this objective, one can use the very important data provided in this thesis, and ultimately better and more accurate results can be extracted using this approach. The main aim of this thesis is to study the effect of increasing the number of floors on how to extend the stress on the building structure. To this end, the number of floors increased from three to five. Therefore, it can be concluded that an increase in the number of floors also more than 5 storey causes stress values, but these modes are quite consistent with the three- and five-storey buildings.

Abstract:

The steel plate-concrete structure, with its advantages of modular construction, good seismic capacity, and strong impact resistance, has been gradually replacing the reinforced concrete structure in the containment vessel and internal workshop structure of nuclear power plants in recent years. In this study, the out-of-plane single-point loading test and parametric finite element simulation analysis were conducted on five steel plate-concrete wall slab specimens with different stud spacings, shear span ratios, and steel contents. Results showed that the steel plate-concrete wall slab under the out-of-plane load had the same failure mode as that of an ordinary reinforced concrete wall. The out-of-plane shear capacity of the steel plate-concrete wall slab increased significantly in the case of numerous studs. With the increase in shear span ratio, steel plate-concrete members suffered a bending failure. When the steel content was low, they had diagonal tension failure, such as a rare-reinforced concrete wall. The out-of-plane bending and shear mechanism of the steel plate-concrete shear wall was studied theoretically, and the calculation formulas of the bending and shearing capacities were derived.

Abstract:

The structural behavior of a steel reinforced concrete (SRC) transfer beam in high-rise building is studied in the paper. Mechanical properties and deformation characteristics between transfer beam and shear wall are analyzed by an analytic approach and the nonlinear finite element method. The stress analytical solutions for the SRC transfer beam are obtained and agree with finite element calculation data in an actual project. The results show that the beam can be as an eccentric tension member, meanwhile the performance of shear wall must be considered. And it also shows that the shear stress and vertical compressed stress must be considered in end both transfer beam and shear wall and there is interaction between the beam and the shear walls above. The results can be used to describe the behavior of the SRC transfer beam under complicated loads.

Abstract:

Through low cycle reverse tests of three steel fiber reinforced concrete coupled shear walls, the crack pattern, bearing capacity, stiffness and displacement are analyzed. Test results show that the bearing capacity, yielding stiffness and the anti-crack performance of the coupled shear walls are generally improved by adding steel fibers to reinforced concrete coupling beams, and the stiffness degeneration is also reduced to a certain degree. More cracks are induced by steel fibers bridged the main crack, which can make the shear wall consume more energy.

Abstract:

This paper investigates shear flow strength of insulated concrete sandwich panels with glass fiber reinforced polymer (GFRP) shear connectors based on push-out test. The precast insulated concrete panels consist of 60mm concrete wall, 100mm insulation, and 130mm concrete wall. Two concrete walls were connected with GFRP corrugated shear connector. Four specimens with variables such as the insulation type and the width of GFRP corrugated shear connector were made. Failure modes, shear flow-deflection relationships and post-peak strength were investigated. Test results indicate that the specimens with EPS insulation show higher shear flow strength than those with XPSS insulation due to the relatively high surface roughness of EPS insulation, and the shear flow strength increased with increasing shear connector width.

Abstract:

The steel fiber reinforced concrete (SFRC) shear wall with concrete filled steel tube (CFST) columns is an innovative composite structure. In order to calculate the shear strength of SFRC shear wall with CFST columns, the softened strut and tie model (SSTM) of SFRC shear wall with CFST columns was proposed based on the analysis of shear mechanism of SFRC shear wall with CFST columns. The SSTM was composed of diagonal, horizontal, and vertical mechanisms, in which the contributions of concrete, reinforcement, and steel fiber to the shear strength of SFRC web of shear wall were identified. The shear capacities of 24 shear walls were calculated and compared with the available test results, and reasonable agreement was obtained. The results also showed that the steel fibers distributed randomly in concrete could be treated as longitudinal and transverse reinforcement in the shear strength analysis of SFRC web, and the SSTM was reasonable and useful to analyze and predict the shear strength of SFRC shear wall with CFST columns.

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:

As an indispensable force component to the hybrid structure, the seismic wave energy inputted into integral structure is dissipated by damping force working and plastic hysteresis of reinforced concrete shear wall which is taken as the first seismic fortification line of structure. Considering of the condition that the RC shear wall is mainly used to dissipate the seismic wave energy, this paper takes the ultimate energy dissipation capacity of reinforced concrete shear wall subjected to cyclic loading as the damage characterization. According to the related theoretical analysis and experimental research, the method for calculating ultimate energy dissipation capacity of RC shear wall is proposed and the damage sensitivity of various design parameters which contain the sectional thickness, the strength of concrete and reinforcement ratio are analyzed, then the influence laws of main design parameters impacted on damage evolution of RC shear wall are revealed in this paper. The research shows that sectional thickness is the most sensitive factor in the damage of reinforced concrete shear wall and the concrete strength degree takes the second place, and then the reinforcement ratio is the most insensitive design parameter. The research achievements will provide theoretical support for establishing the storey damage model of SRC frame-RC core wall hybrid structure under seismic excitation.

Background: To study the flexural behaviors of the concrete shear walls with precast hollow slab, one cast in-situ reinforced concrete shear wall and two precast two-way hollow slab shear walls (PTHSWs) vertical joint were tested under low cyclic loading. Objective: The study showed that vertical joints of PTHSW are safe and reliable to ensure the effective connection between the assembly units. The ductility coefficient of shear wall is larger than 7, so this kind of shear wall has good ability of deformation especially under earthquake load. Results: The interface can effectively ensure the integral performance of PTHSWs and its effect on the flexural behaviors of PTHSWs could be ignored.

Abstract:

Detailed observations are reported for eight shear wall buildings from the Concepción region that experienced severe damage during the 27 February 2010 Chile earthquake. The repetitive nature of some of the damage suggests that these field observations may be applicable to similar buildings elsewhere, whereas other damage may be unique. Several shear walls experienced failures that apparently started at the boundaries due to the high compression in these unconfined edges, and propagated into the wall web. Other walls, including horizontal and vertical wall segments in perforated walls, experienced shear failure. Damage also was observed in columns, beams, and coupling slabs. In most cases, the percentage of damaged elements was less than 10% of the lateral force-resisting elements of the building, suggesting that these structures were not capable of distributing damage. Several building indices are calculated, including vibration periods and regularity indices, for comparison with observed behavior.

Abstract:

Assembled shear wall built with precast two-way hollow slab is a new-typed shear wall built with precast concrete. In order to study its mechanical property, a quasi-static experiment is conducted with 1 reinforced concrete shear wall and 2 new type shear walls as the study objects. It was found that the internal and vertical joints of the wall body were vulnerable parts so that the new-typed shear wall experienced the loading process from the whole wall to the portioned wall. So, brittle shear failure can be avoided, deformability and anti-collapse performance are greatly improved, and shear capacity of wall body is reduced. The new-typed shear wall is reasonably structured, with convenient and reliable horizontal and vertical reinforcement, which leads to satisfactory vertical joint force-bearing capacity. Thus, it can be applied in practical construction.

Abstract:

This paper examines the behavior of reinforced concrete shear wall buildings subjected to strong earthquake ground motions, with a focus on collapse performance. The effect of varying the number of stories, shear wall and boundary element dimensions, and reinforcement detailing on the seismic collapse fragility is investigated. The buildings are seismically designed based on the ASCE 7-10 and ACI 318-14 codes with additional provisions for capacity design and dynamic amplification. The shear walls are modeled using the shear-flexure interaction multiple vertical line element model with nonlinear hysteretic material models. Incremental dynamic analysis is performed to simulate the structural collapse of the two-dimensional building models subjected to the FEMA-P695 set of far field recorded ground motions scaled to increasing intensity values. For each building, a lognormal collapse fragility curve is fitted to the results. A collapse assessment of the studied buildings shows how the seismic performance is significantly affected by the varied parameters.

Abstract:

In this study, two reinforced concrete (RC) squat shear walls with height-to-length ratio of 0.55 and non-ductile reinforcement details are tested under reversed cyclic loading. Emphasis of the study is placed on the hysteretic behavior and cracking procedure of RC squat shear walls in accordance with the presence and absence of vertical seam on the wall panel. Two specimens had the same rectangular cross-section of 1,100 x 50mm, with wall panel heights of 600mm. To investigate the effect of vertical seams on the wall panel on the structural behavior of shear wall, one wall (CON-S) with three vertical seams with dimension of 260 x 40mm was made and the other (CON-N) was a solid wall without seams. The test results indicated that a squat shear wall with vertical seams exhibited more stable hysteretic behavior than a solid shear wall. Vertical seams on the wall panel improve the ductility and energy dissipation capacity but decrease the maximum strength of RC non-ductile squat shear wall.

A structure type of composite shear wall is presented, the both sides of which are reinforced cement composite layer and the middle layer of which is concrete. In order to verify the cooperative work performance of cement-base composite layer and concrete, static load tests were carried out. In the test, the deformation properties of composite shear walls and the development law of the strain of concrete and steel were studied. Meanwhile, a normal shear wall with the same conditions was tested and the corresponding natures of two types of shear wall were contrasted and analyzed. The test results prove that the composite shear wall has a good overall deformation behavior, and can, to some extent, slow down the process of wall stiffness degradation. The research production has provided a foundation for the further exploration to the working properties of the composite shear wall under cyclic loading.

Abstract:

Shear walls are specifically meant to withstand lateral forces exerted by either wind or earthquake loads on a structure. Due to their superior strength and stiffness, shear walls have been an integral feature of mid-rise and high- rise structures over the past two decades. Various studies have been performed in this field. Usage of post-tensioned tendons in the traditional shear wall is one of the major advancements in recent times so as to increase the stiffness and reduce the damage incurred by destructive earthquakes. The key advantage of post-tensioned shear walls is the potential to re-centre after a devastating earthquake which is lacking in conventional reinforced concrete (RC) shear walls that rely on yielding creating large deformations. Moreover, compared with conventional shear wall construction, post-tensioned shear walls can reduce the use of vertical mild steel reinforcement. This results in materials being used more effectively and eliminates congestion. This paper seeks to review and analyze the research studies based on post- tensioned shear wall focusing on works published within the last decade. Firstly, the benefits of using post-tensioned shear walls in seismically active areas are illustrated. The behaviour and parameters controlling the performance of post-tensioned shear walls are then studied. A critical study of the factors responsible for the performance of post- tensioned shear wall is the primary objective of this review.

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:

Reinforced concrete coupled walls are cantilevered shear walls joined by coupling beams and are used in high-rise apartment for many years. Rectangular openings are the most common shape of openings used in shear wall in order to provide doors, windows, entrance to car park areas and elevators or staircases. Behavior of coupling beams affect the strength of coupled walls. This research suggests adding haunches to the corners of rectangular openings and form octagonal openings as a method to increase the strength of coupling beams. The experimental results of shear wall with single band of rectangular and octagonal openings are compared in terms of behavior of coupling beams under cyclic load. The results demonstrate that the coupling beams in shear wall with octagonal openings are stronger than coupling beams in shear wall with rectangular openings.
