| 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。

| 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. |
