摘　　要：为了探究高层建筑的风振响应的问题,选用高层建筑中最常用的框架核心筒与剪力墙两种结构形式。在同样的条件下,运用ANSYS软件,进行两种结构的静力学分析、模态分析和风振响应分析。经过数值计算,得到两种结构的自振频率和变形特征;根据模态分析的结果,选用脉动风谱的Davenport谱,得到两种结构的最大位移和最大加速度。经过对比,得出:框架核心筒结构的抗风性能要优于剪力墙结构。In order to explore the wind-induced vibration response of high-rise buildings,the frame core tube and shear wall is selected in this paper,which are the most commonly used structures in high-rise buildings.Under the same conditions,the static analysis,modal analysis and wind-induced response analysis of the two structures are carried out by using ANSYS software.After numerical calculation,the natural frequency and deformation characteristics of the two structures are obtained.According to the results of modal analysis,the Davenport spectrum of fluctuating wind spectrum is selected to obtain the maximum displacement and acceleration of the two structures.After comparison,it is concluded that the wind resistance performance of frame core tube structure is better than that of shear wall structure.
