ASEISMIC ANALYSIS ON SLITTED SHEAR WALL STRUCTURE BY COMPARING WITH COMMON SHEAR STRUCTURE

A kind of new structural system, slitted shear wall structure with heat preservation formwork by GHB (glazed hollow bead), was presented. The seismic dynamic analysis on the building structured by slitted shear walls was conducted by using ANSYS software. Meanwhile, the common shear wall model was established to contrast with the experimental building structure model. The frequencies and vibration modes of two structures were analyzed, and the elastic deformation of the structure under the earthquake loading was calculated by using the time-history analytic method to find out the failure type of the structure. The result of simulation analysis shows that the slits could reduce the self-weight and stiffness of the structure. The frequency of this structure is less than that of a common shear wall structure，and in turn, the slits could moderate the structural reaction to earthquake. In addition，the simulation analysis on this new type of the structure under actual earthquake wave and simulated earthquake wave is presented. The results show that the elastic inter-storey drift and top displacement is very slight in the case of frequently occurred earthquake, so this new type of the structure has strong stiffness and capacity of seismic resistance.
