| 摘 要： | 研究了SMA(shape memory alloy)绞线-叠层橡胶复合支座的工作原理,将结构控制理论中的结构状态空间法应用到该复合支座隔震结构的数值模拟分析中。建立了普通框架、安装叠层橡胶支座和安装SMA复合支座框架的结构状态方程,应用SIMULINK工具箱建立结构仿真模型,得出不同条件下框架结构的时程反应曲线。通过对比分析可以看出SMA-复合支座能很好地改变结构的隔震效果,应用状态空间法进行SMA-复合支座隔震结构的数值模拟分析简单准确。

| Abstract: | The operating principle of SMA strands-composite bearing was studied,and the state space method of structure control theory was used in shock isolation analysis based on the composite bearing.The state space equation was established based on the common frame and the frame was controlled by laminated rubber bearings or SMA strands-composite bearings,and the simulation model was established by SIMULINK tool box,then the seismic responses under three conditions were gotten.The results show that the seismic responses are reduced obviously as using the composite bearing,and the state space method used in shock isolation analysis of SMA strands-composite bearing is simple and accurate. |
