摘　　要：利用有限元软件ABAQUS6.5对普通中心支撑框架结构、采用低屈服点钢材的防屈曲中心支撑框架结构模型进行了大震时程分析。发现采用低屈服点钢材的防屈曲支撑,不仅解决了支撑杆件的失稳问题,而且明显减小了结构位移等响应,优势明显。Using ABAQUS6.5 the time-history of the followed models is analyed: the model of common central braced frame,and that of central braced frame using BRB with low yield point steel under big earthquake,it is found that using BRB with low yield point steel,can not only solve the problem of buckling,but also all decrease displacement response.

关 键 词：防屈曲支撑 中心支撑框架 地震反应分析 双重非线性 低屈服点钢材
