Hysteresis Characteristics

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.

Steel Trusses

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.

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.

Four test pieces with different steel plate center-to-center distances and reinforcement ratios are subjected to low-cycle repeat quasistatic loading to optimize properties as failure mode, hysteretic curve, skeleton curve, energy dissipation parameters, strength parameters, and seismic performance of high-strength concrete low-rise shear walls. The embedded steel plates are shown to effectively restrict wall crack propagation, enhance the overall steel ratio, and improve the failure mode of the wall while reducing the degree of brittle failure. Under the same conditions, increasing the spacing between the steel plates in the steel plate concrete shear wall can effectively preserve the horizontal bearing capacity of the shear wall under an ultimate load. The embedded steel plates perform better than concealed bracing in delaying stiffness degeneration in the low-rise shear walls, thus safeguarding their long-term bearing capacity. The results presented here may provide a workable basis for shear wall design optimization.
