摘要

为了消除防屈曲支撑在强震后留有残余变形的弊端,本文针对一种新型支撑构件—自复位防屈曲支撑,通过有限元软件ANSYS对自复位防屈曲支撑钢框架、防屈曲支撑钢框架和钢框架进行罕遇地震作用下的抗震性能对比分析。结果表明,自复位防屈曲支撑钢框架的顶点位移、层间位移角、残余变形等地震响应均明显小于防屈曲支撑钢框架和钢框架,尤其在残余变形方面,自复位防屈曲支撑基本消除了结构的残余变形,具有良好的复位效果。
In order to eliminate the disadvantages of the residual deformation of the buckling- restrained brace after the severe earthquake,this paper contraposes a new type of brace components-self- centering buckling- restrained brace and a comparative analysis of the seismic performance of self- centering buckling- restrained brace steel frame,buckling- restrained brace steel frame and steel frame is done by using general finite element software ANSYS. The results show that top displacement,inter- storey drift angle,residual deformation etc. of self- centering buckling- restrained brace steel frame are much smaller than buckling- restrained brace steel frame and steel frame.Especially in the aspect of residual deformation,self- centering buckling- restrained braces eliminates main residual deformations of structure,showing expected re- centering effect.
