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.

Reinforcement Scheme

Coupling beam, the first line resisting earthquake, is directly related to the overall performance of the shear wall structure. Using the large general finite element analysis software ANSYS, the coupling beam span-depth ratio is 2~3 different reinforcement scheme in finite element analysis. Analysis on the ductility performance of reinforced concrete coupling beams in shear wall structure in three fields: the concrete strength grade, the longitudinal reinforcement ratio and the stirrup ratio, provides a basis for the design of the structure and to provide a reference for similar studies.

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.

Wall System

One of the types of earthquake-resistant systems is the concrete shear wall system, which has attracted the attention of engineers due to its good performance in past earthquakes. But some architectural constraints force engineers to install openings in shear walls; thus, this will affect the behavior of the shear wall. Many researchers have conducted experimental and finite element studies for assessing the effects of openings in reinforced concrete shear walls. However, there is a lack of comprehensive comparisons between different studies. This paper reviews some most recent experimental and finite element studies available in the literature and presents a review of the main contributions. This literature review reveals that the seismic responses and the stiffness of structures are influenced by the size and location of the openings in the reinforced shear wall.

Shear Panel

This paper presents what is believed to be the first successful attempt to apply an elastoplastic material model to planar reinforced concrete under cyclic loads. The model treats an element of reinforced concrete in biaxial stress states, and provides for the cracking and crushing of concrete, opening and closing of previously formed cracks, and yielding of steel reinforcement. The model offers both computational efficiency and an adequate level of accuracy.A rectangular plane stress finite element with three degrees-of-freedom per node, two translations, and an in-plane rotation is employed to discretize the continuum. The presence of rotational degrees-of-freedom at nodes allows an application of the proposed model to the analysis of coupled shear walls and shear wall – frame systems.When the nonlinear finite element analysis results are compared with the experimental response of a shear panel and a shear wall subject to reversed cyclic loads, a good comparison is achieved. The analytical results for the shear panel are also compared with those obtained by other investigators using a degrading nonlinear material model, and a close correspondence is obtained.
