摘要
在研究形状记忆合金(SMA)绞线-叠层橡胶复合支座基础上,本文提出了SMA复合支座-巨型框架减震结构体系,建立了SMA复合支座-巨型框架减震结构体系的计算模型和运动方程,研究了该结构的动力反应特性,并将其与普通巨型框架结构、应用普通橡胶支座巨型框架结构进行了非线性时程对比分析。结果表明,SMA复合支座-巨型框架减震结构体系能有效地减小结构的地震响应,同时避免了地震时主次结构之间产生碰撞破坏。
This paper introduces a new mega-frame structure with an SMA compound bearing on the basis of SMA wire-laminated rubber combined bearings research. We built the calculation model , formulated the motion equation and studied the dynamic characteristics. In addition ,we made a comparison between the common mega-frame and the mega-frame with a common rubber bearing by nonlinear time-history buffeting analysis. The results show that this structure system could effectively reduce the seismic response of the structure and prevent the colliding damage to the main structure and the sub-structure during earthquakes.
