使用PPM2008软件设计了一榀12层5跨的纯混凝土框架,并在此基础上设计了4榀不同支撑布置的Y型偏心支撑框架试件。采用SAP2000.V14建立非线性有限元模型,分别对这5种试件进行地震反应分析。通过数据对比分析表明,楼层柱承担的总剪力随支撑布置的跨数增加有所下降;每层耗能段承担的剪力占楼层总剪力的比重在一个相对固定的范围内变化,且这个比重随支撑布置跨数的增加而上升。

In this paper,a RC frame with twelve stories and five spans was designed by PKPM2008,on which the Y-eccentricity braced frames（EBF） specimens with four frames of different brace arrangements were designed.SAP2000 was used to set up the nonlinear finite element model and analyze the earthquake response of the five specimens.The comparison and analysis of the data show that the shear force undertaken by the column of each floor declined with the span increase of the brace arrangement,and the ratio of the shear force undertaken by the link beam of each floor only changed in a relative regular scope,this ratio became higher and higher with the increase of the span number of the brace arrangement.
