摘要
以某大底盘双塔框架为例,通过建立层间隔震与在此基础上底盘采用金属或粘弹性耗能原件的多种有限元模型,对改造后建筑物进行罕遇地震作用下的地震响应进行分析,并对比了各结构中层位移、剪力及顶层加速度的变化程度,得出对于大底盘结构下部宜采用粘弹性阻尼器的结论。
A twin towers and large chassis frame as an example, through the establishment of the isolation layer and on the basis of the chassis using
a variety of finite element model of metal or viscoelastic damping of the original, the response was analyzed and compared the variation degree
of structure layer displacement, shear force and acceleration of the top of the rare earthquake after the transformation the large buildings, for the
lower chassis structure should adopt the viscoelastic damper conclusion.
