摘　　要：高层建筑顶部消防水箱会对建筑物的地震响应产生影响。本文采用非线性动力分析法,将建筑物顶部消防水箱的水体与水箱壁之间的力学模型简化为Housner水体模型,并且利用有限元分析软件,对水箱结构体系进行动力特性分析和弹塑性时程分析,进而验证了消防水箱对高层建筑抗震性能的影响。The fire tank on the top of high-rise building will affect the seismic response of buildings.In this paper, the nonlinear dynamic analysis method is used to simplify the force between the water body of the fire water tank on the top of the building and the wall of the water tank into the Housner water body model, and the finite element analysis software is used to analyze the dynamic characteristics and elasticplastic time-history of the water tank structure system,so as to verify the influence of the fire water tank on the seismic performance of high-rise buildings.
