Abstract:The low cyclic loading experiment was conducted for a 1/3 scale one-bay two-story concrete-filled square steel tube frame-thin steel plate shear wall with middle openings. The influence of middle opening of steel plate shear wall on the seismic behavior was investigated for the concrete-filled square steel tube frame-thin steel plate shear wall. The nonlinear numerical analysis of the concrete-filled square steel tube frame-steel plate shear wall with middle openings by using the finite element software ABAQUS. The influence of different parameters on the mechanical properties were analyzed, including the location of the steel plate shear wall opening, the ratio of opening width to the steel plate shear wall width, the thickness of infill plates and stiffening ribs. The analytical results show that the location of the opening has little influence on the mechanical behavior of the structure. The stiffness and strength of the structure decrease with the increase of the ratio of the opening width to the steel plate shear wall width. The increase of the infill plates′ thickness enhances the bearing capacity and the initial stiffness of the structure. Setting the stiffening ribs around the openings decreases the width-to-thickness ratio of infill plates and declines the influence of the steel plate shear wall on the vertical boundary member.

Keywords:concrete-filled square steel tube frame; thin steel plate shear wall; middle opening; the ratio of the opening width to the steel plate shear wall width; mechanical behavior
