This paper describes the study about multilayer and high-rise precast prestressing shearwall structure ,we made one shape,T shape and linked limb shearwall specimens as the objects,we also made comprision with cast-in-place shearwall,the specimens were tested under high frequency and reciprocating horizontal load.Based on the test,we used the finite element software ANSYS to do a nonlinear elasto-plastic analysis about the whole process under different compression ratios and different effective prestress to research seismic performance, failure mode and elasto-plastic analysis.The results show that the edge members are the maximum force position and the most important energy dissipation part of the shearwall limb.

The semi-rigid steel frame-composite steel plate shear wall structure (SCSW) effectively improves the lateral stiffness of shear wall, making it possible to use the semi-rigid joint. In order to study the plastic failure mechanism of SCSW, a plastic model is established, in which the effects of the rotations of semi-rigid joints and yield deformations of infill steel walls on the energy consumption are considered. Based on that, a design method for the lateral ultimate strength is put forward and a nonlinear FEM model is setup using ANSYS. Through the comparison between plastic analysis results with the finite element results, it is shown that the plastic analysis method is feasible and has a safe redundancy.
