摘　　要：研究基于SMA绞线-叠层橡胶复合支座的底层框架砌体结构隔震理论和方法,建立了底层框架砌体结构在隔震体系中的动力方程,同时分析一典型底层框架砌体结构在地震作用下结构的时程反应。研究表明,SMA绞线-叠层橡胶复合支座是一种有效的隔震装置,它用于底层框架砌体结构中,能有效地减小结构的位移、速度以及加速度时程反应,使底层框架砌体结构的地震响应明显降低。Study on the SMA strands- composite bearing based seismic isolation theory and method of ground floor-frame masonry building is carried out. In the paper, the dynamic analysis of seismic isolation system of ground floor-frame masonry building and time history analysis of a ground floor-frame masonry building under earthquake are also carried out. The results indicate that, SMA strands- composite bearing is an effective seismic isolation device in the ground floor-frame masonry building and can effectively reduce the seismic response, such as displacement, velocity and acceleration of the structure.
