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.

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.
