地震作用下高层建筑静动力特性分析

The static and dynamic characteristics analysis of high-rise building under the earthquake

依据抗震设计规范,采用有限元分析软件SAP2000,对15层钢筋混凝土框架结构动力特性和地震时程反应进行分析,通过计算得到了该类建筑物的自振特性以及在地震作用下的位移和加速度反应,以提取建筑的薄弱环节,为结构的合理设计提供参考。

According to seismic design code, a fifteenth floor reinforced concrete frame structure was analysed include dynamic characteristics and seismic time history response using the finite element analysis software SAP2000. The natural vibration characteristics and the displacement and acceleration response of structure were obtained under seismic action, and weak link in construction was extracted, providing a reference for structure with reasonable design.
