Abstract:This paper designed one specimen in the light of a steel plate shear wall with two-side connections and side stiffened. This specimen was tested under cyclic loading at a scale ratio of 1/3 to investigate its hysteretic behavior. Finite element analysis model of this specimen was established by using finite element software ABAQUS to simulate its hysteretic behaviors. Finite element results and experimental results were made a comparison to verify the reliability of the finite element model. The influences of aspect ratio, height-thickness ratio and thickness of stiffener on hysteretic behaviors of this steel plate shear wall with two-side connections and side stiffened were investigated by using the verified finite element model. Research results show that the full degree of hysteresis curve, which is not related to the variation of the thickness of the stiffeners, decreases with the decrease of aspect ratio and increases with the decrease of the height-thickness ratio. Cumulative energy consumption per unit increases with the decrease of the aspect ratio, with the decrease of height-thickness ratio and with the increase of the thickness of the stiffeners, and the influence of height-thickness ratio is the most significant among them. The change regulations of maximum average shear stress is in accord with cumulative energy consumption per unit and maximum average shear stress is close to the shear yield strength gradually. The above research provides a basis for the design and application of steel plate shear wall.
