摘要
基于形状记忆合金的超弹性效应,将形状记忆合金和滑移支座复合成一种新型的隔震支座:SMA-滑移支座.并应用在一隔震结构上.推导了地震激励下该支座隔震结构的运动方程,对滑移隔震结构进行了数值模拟分析.结果表明,支座具有良好的隔震性能,可有效的应用在隔震结构的振动控制上.
Based on the super-elastic behavior of the shape memory alloy,a new type of SMA sliding bearing is developed by compositing shape memory alloy(SMA) wires with the sliding bearing,and is used in one base-isolated structure.In this paper,a motion equation of this is deduced under the ground motion.A numerical simulation analysis about the seismic isolation is investigated.The results show that the new SMA sliding bearing has nice seismic isolation performances,and is very effective in vibration control of the base-isolated structure.
