The Seismic Behavior Reash On V Eccentric Braced Steel Frame Based On Pushover Method

The elasticity phase stiffness of the V style eccentric braced steel frame is approach to the centre braced steel frame,in the plasticity phase the transformation and the ability of consume earthquake energy is approach to frame structure. Its elastic-plastic character is analyzed and a model which has six stories has been discussed in this paper with the nonlinear static Pushover analysis. The main study contents of thin paper are followed:(1)The paper analyzed and studied the general situation of the steel-frame system and the method of nonlinear Pushover analysis.(2)Based on the previous study, this paper has discussed the design theory for the V style eccentric bracing steel.(3)The theory of the analysis method of nonlinear Pushover has 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 Pushover, at the same time, it has studied the ability of distortion the demolish mechanism of the model under the different earthquake, from the result the paper has assessed the capability of the structure under the different earthquake, at last, the based distance has been studied which can effect the capability of the structure.
