Analysis of Seismic Response of a High-rise Frame-shear Wall Base-isolated Structure
摘要
Abstract
Taking the high-rise frame-shear wall base-isolated building structure as the research object, a nonlinear finite element model is built for qualitative analysis by using the elastic-plastic constitutive model of isolation equipment considering the change relation of tension and compression stiffness in vertical direction and the elastic model of frame-shear wall. The research on the seismic response of a high-rise frame-shear wall base-isolated structure is performed by the time-history analysis of the structure. The analysis results show that the nonlinear hysteretic property of isolation bearing meets the basic design requirement of bearing design. The low order periods of high-rise building are extended by using the base isolation technology. The acceleration response and inter-story displacement angle of the upper structure are decreased obviously. Most of ground motion energy is consumed by isolation layer, and the seismic response of a high-rise frame-shear wall structure can be effectively decreased by using the seismic isolation technology.关键词
