Abstract：In order to study aseismic performance of porous butterfly-shaped steel plate shear wall, low cycle cyclic loading tests of 4 full-scale specimens were conducted. On the premise of the waist width ratio of butterfly bar being controlled at 0.4, effects of steel plate thickness and opening rate on hysteretic performance, load-bearing capacity and energy dissipation performance of porous butterfly-shaped steel plate shear wall were studied. The test results showed that porous butterfly-shaped steel plate shear wall has good aseismic performance and is an ideal anti-lateral force component and energy dissipation component; its ultimate failure mode is end tearing of butterfly rod on the outermost side of the steel plate; with increase in thickness of the steel plate wall and decrease in its opening rate, lateral stiffness and load-bearing capacity of specimens increase and their energy consumption increases.
