We calculate the structure in rare earthquake using elastoplastic time-history method. The results are compared such as the story shear, story drift, the time history displacement of the top point and the structure plastic deformation. Through calculation, we conclude that the buckling restrained braces have some effects in controlling stiffness mutation and story shear mutation. This conclusion can be used in similar structures.Keywords：connected structure; buckling restrained braces; SAP200; elastic plastic time history analysis
