Abstract
Through setting the constraints on the fringes of the bar element inhibition of compression buckling under pressure ,buckling-restrained support can achieve better effect of energy consumption. In order to further study the effect of anti buckling brace on the seismic behavior of steel frame structure, the paper used SAP2000 finite element software to analyze the mode and time of a steel frame of whole model under the condition of buckling brace, general center support and the forms of non support. The results showed that the period of buckling restrained brace steel frame and the displacement angle of the layer are all reduced compared with that that of the pure frame. In the case of rare earthquake, the top-maximum displacement value and the top acceleration of the steel frame are more significantly reduced than that of ordinary braced steel frame. The result indicated that the stiffness of steel frame can be obvi-ously improved by using the anti buckling brace, and the seismic performance of the steel frame structure is greatly improved, and the energy dissipation effect is obvious.关键词
