有限元在高层建筑结构分析中的应用

Application of Finite Element on the Analysis of Tall Building Structure

首先对框架-剪力墙的结构形式与特点进行简单介绍。结合一个通用的框架-剪力墙结构例子,说明了有限元软件在分析高层建筑结构中应用,计算了该类框剪结构自重下的变形及应力分布情况,并通过模态分析了解了该类结构的基本动力特性。

Firstly characters of frame-shear wall structure are introduced in this paper. According to a common engineering example of frame-shear wall structure, the predominant analysis competence of finite element software in dealing with tall building analysis is verified. During the analysis process, the basic static response （displacement and stress） is known and the dynamic character of this structure is also taken by modal analysis.
