摘　　要：研究了基于SMA绞线-叠层橡胶复合支座的框架结构隔震理论和方法,建立了3种不同支承条件下单自由度隔震体系的运动方程,并对一个典型的4层框架结构,分析了它在地震作用下的时程反应。结果表明,SMA绞线-叠层橡胶复合支座是一种有效的隔震装置,它用于框架结构中,能有效地减小结构的位移、速度和加速度反应。Study on the seismic isolation theory and method of frame structure based on composite SMA strands- laminate rubber bearings is carried out, motion equations of unidirectional seismic isolation system with three different beatings respectively are established, and the time history analysis of a typical four-floor frame structure under rare earthquake is also conducted. The rusuh shows that, the composite SMA strands-laminate rubber beating is an effective isolation device and the seismic response, such as displacement , velocity and acceleration of the structure with application of the device would be reduced effectively.
