摘　　要：以一不满足抗震规范要求的不规则钢框架为例,对其采用增设防屈曲支撑的方法进行抗震加固,并运用有限元软件SAP2000对原结构及加固后的结构分别进行多遇地震和罕遇地震作用下的时程分析。分析结果表明:在不改变原有建筑物外形的基础上,增设防屈曲支撑能够减小不规则结构的周期比及位移比,满足了规范要求,为同类结构的抗震加固提供了一种简单有效的方法和途径。Taking an irregular steel framework not meeting with the requirements of the anti-earthquake code as an example,an anti-yield support method was applied to the anti-earthquake reinforcement and the finite element software SAP2000 was applied to the time history analysis on the structures of the original structure and the reinforced structures individually under the role of the multi earthquakes and unusual earthquake.The analysis results showed that base on no change to the profile of the previous building,the anti-yield support could reduce the periodical ratio and displacement ratio of the irregular structure,could meet the requirements of the code and could provide a simple and effective method and access to the anti-earthquake reinforcement of the similar structure.
