隔震设计在某民用建筑中的应用
|
摘要
本文介绍了利用midas gen对某隔震结构进行结构分析。利用midas gen非线性有限元时程分析方法,通过计算对设置隔震支座前后结构的有关参数进行对比分析,如自振周期、层间剪力、顶点绝对加速度,分析结果表明,采用隔震支座后可以显著降低上部结构的地震作用。
The paper describes the MIDAS gen structural analysis of an seismic isolation design.The MIDAS gen nonlinear time history program is adopted in the design of the seismic isolation structure,through the calculation analyze the relevant parameters of structure,with or without seismic isolation,such as the natural vibration of period,storyr shear,vertex absolute acceleration,the analysis results showed that the seismic isolation bearing can be significantly reduced the upper structure of the earthquake action.
