Currently, housing is in the full swing development and is becoming a new economic growth point, the new materials, new forms of housing system and the structure of a higher have been demanded. With the idea a low carbon economy threw, the traditional construction of low-technology and raw material consumption can not meet the requirements. Finding new materials, new structural system of the housing industry to use means it came into being. This article is based on the concept of common walls, a new type of shear wall structure - composite slab of concrete shear wall structure, the structural system Weide introduced the West German company advanced production technology and process.This wall structure has the excellent performance, cost of economic rationality, to overcome the plain concrete shear wall long construction periods and large amount of defects.This article designed a composite plate shear wall specimens and a place concrete shear wall specimens to do low cyclic loading tests and observed the process of the failure of the wall, according to the test situation and test data we obtained the lag Back to the skeleton curve, ductility ratio, etc, through the carrying capacity, deformation, energy properties (cracking load, yield load, ultimate load, stiffness degradation and the ductility, etc.) three specimens to identify and assess the seismic performance. It aslo compared the differences among the destruction of shape, bearing capacity, deformation capacity and energy dissipation capacity of the composite slab concrete shear walls and pouring concrete shear walls. The results show that the specimen of the composite plate shear wall has good overall performance. In addition, combining the test means and the finite element theory, using ANSYS program modeled on the two wall panels by the finite element analysis, comparing with the test results, drawong some useful conclusions for the future of this kinds of composite wall panels for computer simulation to provide a reference.
