摘要
本文按照现行抗震设计规范，利用三维有限元软件ＡＮＳＹＳ，对某２７层花园大厦的主体建筑进行了振型分析和地震时程反应分析。得到了该建筑物的自振特性及其在多遇、设防烈度和罕遇地震作用下内力、位移分布和结构物的薄弱环节，并对该建筑物的抗震性能进行讨论。
According to the present Code for Seismic Design of Buildings,for a 27-storybuilding,mode analysis and time historymethod for seismic analysis were carried out by usingANSYS,FEA software.The characteristic of free-vibration,the force and displacement distribution under the three standard intensities specified in the Code,and weakness link of the build- ing are obtained by the analysis.The earthquake resistant behavior of the building also discussed.
