摘要
对 Y型偏交支撑框架进行了弹塑性静力及动力分析 ,选择耗能段的屈服强度、屈服位移、支撑与耗能段的刚度比、Y型支撑与纯框架的刚度比作为影响参数 ,研究了这些参数的变化对结构抗震性能的影响 ,并基于对计算结果的分析 ,对 Y型支撑钢框架中耗能段及支撑的设计提出了建议 .
The elasto plastic static and dynamic analysis on Y type eccentrically braced steel frame(EBF) is made. In view of the yield force、yield displacement of shear link、ratio of the shear link stiffness to the bracing member stiffness and the ratio of Y type brace stiffness to the structural story stiffness without the Y style brace in place have been identified as the most important parameters to characterize the performance of Y type brace. The influence of these parameters on earthquake response of building structure is analyzed. Based on the analysis result, some design recommendations on the shear link and brace members of Y type EBF are also put forward.
