【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。更多还原

【Abstract】 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.更多还原
