EXPERIMENTAL STUDY OF SEISMIC PERFORMANCE ON T AND L TYPES SUPERIMPOSED-SLAB-SHEAR-WALLS STRUCTURE
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.
