The composite shear wall system with permanent thermal-insulation wall form of glazed hollow bead is a new kind of energy-saving building. the experimental study on the seismic performance of composite shear wall structure was proposed. Through the tests of the walls with different shear-span ratio and axial compression ratio under vertical force and low cyclic horizontal load, the seismic behaviors of slitted shear walls under low cyclic load tests were studied. Through the expemental study, the calculation methods for load-bearing capacity of walls with different shear-span ratio were obtained. And then the laws for the energy dissipation and ductility feature were revealed. Besides, the comparison analysis were made on the seismic behaviors between composite shear walls and common shear walls.The study could provide a foundation for the designing evaluating on the performance for the new structure.

Shear wall is the main component that resists the lateral force for high-rise buildings. With the rapid development of high-rise buildings, especially the super high-rise buildings, requirements for seismic performance of shear walls have become more sophisticated. The steel plate concrete composite shear wall shows good seismic performance. It has made rapid development through the research of seismic performance in the way of seismic design to the practical engineering application of steel plate concrete composite shear wall. Recent research situation and prospect of composite shear wall around the world have been introduced in this paper.

The consequences of lateral loads like earthquake loads, wind loads and blast forces are achieving utmost concern nowadays. Imparting sufficient strength and stability in counter to the lateral loads is one of the major challenges faced by every designer. Therefore Proper understanding of the Seismic performance of different types of shear walls is necessary for structural engineers so as to safeguard the structure against lateral loads. The present paper describes the comparison of the seismic performance of high rise buildings and optimizing the thickness of RCC shear wall, Steel Plate Shear Wall (SPSW) and composite shear wall for (G+20) stories. The design and analysis of the  building with RCC shear wall, steel plate shear wall and composite shear wall is carried out using software ETABS. Effect of varying thickness of shear panels and comparison of the results of story drift and story shear is presented.

Composite Shear

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.

The structural system and seismic performance of the composite shear wall are analyzed based on the horizontal load model tests. The test models are three groups of combined shear walls with shear span of 1.5, including an ordinary shear wall, a shear wall with vertical steel plates and a shear wall with transverse steel plates. The finite element software ABAQUS is used to build the calculation model of the shear wall structure. And the analysis the influence of steel plates to bearing capacity, ductility, and stiffness of shear wall are carried out. The research results indicate that the combination shear wall has good seismic behaviors.

Composite Shear

The concept of steel-concrete composite shear wall is introduced due to the benefits achieved by integrating both the materials. These are structural walls, where steel profiles are encased at the boundary elements. Due to their higher lateral strength and stiffness, they offer a good alternative to improve earthquake resistance over conventional reinforced concrete shear walls in medium and high-rise buildings. Current literature shows that, design procedure of such composite shear walls is not addressed in developing country codes. Hence, a design of steel-concrete composite shear wall is proposed in the present paper on the basis of existing theory and with the help of standard codes. The web portion of shear wall has to be designed as per provisions of Eurocode 8. For the design of composite boundary elements, design norms of composite columns are followed. Also the design of shear stud connectors is adopted according to Eurocode 4.
