Its elastic-plastic character is analyzed and a model which has si x stories has been disc ussed in this paper with the nonlinear static Pushover analysis. The main study contents of thin paper are followed: ( 1 ) The paper analyzed and studi ed the general situation of the steel-frame system and the method of nonlinear Pushover analysis. ( 2 )Based on the previous study, this paper ha s discussed the design theory for the V style eccentric bracing steel. ( 3 )The theory of the analysis method of nonlinear Pushover ha s been studied in the paper. ( 4 )Using the SAP2000 to set up a V style eccentric bracing steel frame model, which has been analyzed by the method of Pus hover, at the same time, it has studied the ability of distortion the demolish mech anism of the model under the different earthquake, from the result the paper has asse ssed the capability of the structure under the different earthquake, at last, the based dist ance has been studied which can effect the capability of the structure. Keywords: nonlinear static Pushover analysis; V style eccentric bracing steel frame; plastic hinge; link beam 独创性声明本人郑重声明: 所呈交的学位论文,是本人在导师的指导下,独立进行研究工作所取得的成果。除文中已经注明引用的内容外,本论文不含任何其他个人或集体已经发表或撰写过的研究成果,也不包含为获得河北工程大学或其他教育机构的学位或证书而使用过的材料。对本文的研究做出重要贡献的个人和集体, 均已在论文中
