| 摘 要： | 通过对高宽比为2.5(小高宽比)和5(大高宽比)的高层隔震结构的振动台试验及数值分析表明,高层隔震结构具有较好的水平减震效果.地震作用下,小高宽比高层隔震结构的变形以隔震层剪切变形为主,大高宽比高层隔震结构不仅有隔震层剪切变形,而且也包含上部结构剪切和弯曲变形.进行大高宽比高层或超高层隔震结构设计计算时应同时考虑上部结构剪切和弯曲变形的影响.

| Abstract: | Experimental study and numerical analysis been completed for a high-rise isolated steel frame model with aspect ratio 5 and 2.5 in the paper.The experiment results show that the high-rise isolated structure with small and large aspect ratio have good isolation effect under the earthquake.The shear deformation is more occurred for the small aspect ratio and the bend and shear deformation is occurred for the large aspect ration isolation structure.The bend and shear deformation of superstructure is important ... |
