摘要
利用大型通用有限元软件ANSYS,通过对中国平安金融大厦工程的三维有限元分析,进行了自振特性和地震反应分析。得出了在不同支撑连接方式、不同楼板计算假定下结构的自振周期和振型,分析了在地震作用下结构的层间侧移、层间剪力和薄弱环节,并对不同计算方法对该类结构动力性能的影响进行了探讨,以期对同类工程的分析有较高的参考价值。
A finite element model of Shanghai Ping'an Financial Building is set up using the general FEA program ANSYS, its vibration characteristic and seismic response is calculated. The vibration period and vibration mode according to different connection and different floor assumption are obtained. The storey drift and shear force are analyzed as well as weak storey. The influence of different calculation method on seismic behavior is discussed which is helpful to similar projects.
