Abstract: The seismic problem of a superimposed-slab-shear-walls structure was studied by the experimental method. The key technology of the structural seismic research on a superimposed-slab-shear-walls system was analyzed. Superimposed-slab shear walls was utilized to study the cause of nonlinear detrude-wreck and the parameters of non-elastically dynastic response, where it was focused on the analysis of the hysterics loops, skeleton loops, stiffness degrading loops and ductility of the connections (including T and L types connections) of the superimposed slab that effect the anti-seismic performance of the structure. The results show that the seismic performance of the superimposed-slab shear walls is the same as that of concrete shear walls. According to the research result, the design method of a superimposed-slab-shear-walls structure based on the anti-seismic performance is forward. The local regulation of aseismic design for a superimposed-slab-shear-walls structure has been released and is applied to engineering.
