摘要
与传统的框架 -剪力墙结构相比 ,斜撑框架结构是一种受力更为合理、经济的结构体系 .分别采用有限元分析程序AlgorFEAS和商用建筑结构分析设计程序TAT ,并应用振型分解反应谱方法和时程分析法 ,对斜撑框架结构的地震反应进行了对比分析计算 .计算结果表明 :采用不同的计算方法与计算程序得到的斜撑框架结构体系的自振特性相差较大 ,而结构的内力相差不大 ;目前的商用软件如TAT可适用于斜撑框架结构的工程设计 .
The frame structure with braces is a kind of structure which has more reasonable force bearing behavior and is more economic compared with the traditional frame-shear wall structure.This paper calculates the earthquake response of a frame structure with braces by the finite element analysis program of Algor FEAS and the commercial program TAT,which is commonly used in high building structure design.The results computed by Algor and TAT with the combination of model response analysis method and the time history analysis method are given respectively.The differences of the results by different analysis methods are compared and analyzed.The calculating results show that the vibration properties of the frame structure with braces computed by different analysis methods and analysis programs differ remarkably,but the internal forces of the structure are mainly identical.The commercial program TAT can be used to the engineering design of the frame structure with braces.
