【摘要】 本文分析了摩擦消能支撑及框架主体结构弹塑性本构关系 ,并给出了动力时程分析的计算方法。同时 ,对六层钢框架模型做了各种工况下的地震反应时程分析。结果表明 ,摩擦消能支撑钢框架(FEDBF)比抗弯钢框架 (MRF)的地震作用明显降低 ,尤其在强震作用下效果更加明显更多还原

【Abstract】 In this paper,friction energy dissipation bracing and elastic plastic relation of a frame are discussed. An algorithm for dynamic analysis of time history is presented and imitative analysis for the 6 storey steel frame model under earthquake is adopted.The results show that the FEDBF can effectively reduce the seismic response of the frame model as compared with MRF.更多还原
