基于SMA绞线-叠层橡胶复合支座的结构隔震
Structural isolation based on SMA strands-laminate rubber bearing
【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。
【Abstract】 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 bearings respectively are established,and the time history analysis of a typical four-floor frame structure under rare earthquake is also conducted.The rusult shows that,the composite SMA strands-laminate rubber bearing 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.
【Key words】 composite SMA strands-laminate rubber bearing; frame construction; seismic isolation;
