用ANSYS分析高层钢-混凝土混合结构的地震反应
|
摘要
依据抗震设计规范,采用三维有限元ANSYS软件,对钢框架-混凝土核心筒的混合结构动力特性和地震时程反应进行分析。通过计算,得到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。通过地震动的影响因素分析,明确了结构各类参数的变化对结构反应的影响,为结构的合理设计提供参考。所提供的分析方法为此类结构的抗震性能研究提供了一种有效的途径。
According to the present code for seismic design of building,characteristics of free-vibration and time history method for seismic analysis of steel-concrete hybrid structure were carried out by using ANSYS software.The characteristic of free-vibration,the displacement and acceleration distribution were obtained by the analysis.With the influence factors of seismic analyzed,the rugular of structure responses caused by structure parameters changed were obtained.It provides some reference for appropriate design.One kind of effective approach to study the seismic response of steel-concrete hybrid structure was put forward.
