Abstract：In order to explore the simplified analysis and seismic performance of steel truss with diagonal braces, the simplified analysis for the samples from the previous experiments was carried out based on the finite element software ABAQUS6.10 platform.The seismic performance of the structure was evaluated with the displacement ductility coefficient and equivalent viscous damping coefficient.In the numerical analysis, the B31 beam element was used for the ordinary braces, and the T3D2 truss element was used for the buckling restrained braces.The results show that it is reasonable to simulate the buckling restrained braces with the T3D2 truss element and to simulate the ordinary braces with the B31 beam element.Through studying the hysteretic behavior, ductility coefficient and equivalent viscous damping coefficient of the structure, it is noted that the steel truss structure with the buckling restrained braces has good seismic performance.
