摘要:
以实际工程案例为背景,考虑3到9层的填充墙作用并用等效斜撑代替,根据"刚度补偿"概念,提出了消除薄弱层的防屈曲支撑简化设计方法,并按此方法将防屈曲支撑设置在9层框架的薄弱层1,2层,通过Sap2000建模对比分析了考虑填充墙影响和加防屈曲支撑前后的差别,包含反应谱分析、模态分析、线性时程分析、非线性时程分析等,从而验证了所提设计方法的可靠性。
Abstract:
Based on the background of practical engineering case, this paper considers infill wall function of three to nine floor and uses equivalent brace instead.Based on the concept of compensation stiffness, the simplified design method are proposed to eliminate weak floor by buckling-restraining braces.According to this method we set the buckling-restraining braces in weak first and second floor of a 9 storey framework.By Sap 2000 modeling we considered the infill wall effect and the difference before and after setting up of buckling-restraining brace,including response spectrum analysis, modal analysis, and linear time history analysis, nonlinear time history analysis, etc., and verify the reliability of the mentioned method.
