Abstract:In the shaking table test of steel frames-steel shear wall system, a problem is that thickness of the steel plate shear wall(SPSW) in the scale model is too small. In order to solve this problem, this paper proposes two equivalent models: concentrically braced frames and I shape of buckling restrained steel plate shear walls(BRSPSW) as a substitute for SPSW. Both of the two models are based on principles of equivalent strength and stiffness. Firstly, the finite element analysis program ABAQUS was used to establish the numerical model of prototype structure and equivalent models, and the lateral stiffness and ultimate strength of prototype SPSW and equivalent models were compared and analyzed. The results show the two equivalent substitution models both have good energy consumption capacity and can solve the problem of small thickness. In addition, the concentrically braced frames model can only make sure either lateral stiffness or ultimate load equivalent, but I shape of BRSPSW model can ensure both lateral stiffness and ultimate load equivalent, which provides some suggestions for the equivalent models of SPSW in shaking table tests.
