| 摘 要： | 通过在巨型框架-次框桁架结构中增加隔震装置,得到巨型框架-次框桁架结构隔震减震体系。采用ANSYS有限元程序对该隔震减震体系进行了隔震减震动力时程计算,得到该结构体系在多条地震波作用下的地震响应。计算结果表明,巨型框架-次框桁架结构隔震减震体系是一种抗震性能良好的结构体系,可改善巨型结构的受力,具有优良的抗震性能:主、次框架顶点位移相对于巨型框架-次框桁架结构的顶点位移明显减小,主框架位移最大减少约47%,次框架最大减少约64%;主框架地震内力最大值响应低于巨型框架-次框桁架结构,剪力减少约33%,弯矩减少约34%。计算结果对巨型结构的抗震设计有较大的参考价值。

| Abstract: | A new-style structural seismic isolation system is put forward by adding the isolation device into a mega-frame-sub-truss-frame system.The system's seismic response under several earthquake waves,such as the dynamic time history response,is obtained by using a general finite element program ANSYS to calculate the seismic isolation and resistance performance.The calculation results show that the mega-frame-sub-truss-frame system is a well-behaved structural seismic system.It has good seismic resistance perfo... |
