Abstract Relevant studies into the high load-bearing capacity steel plate shear wall used in the high-rise building are insufficient, especially for steel plate shear walls whose yield load exceeds 3000kN. This paper developed a kind of high load-bearing capacity steel plate shear wall with yield load no less than 3000kN to be applied in the frame-steel plate shear wall structural system which has been utilized in the design and construction of high-rise buildings in China. Low-Yield-Point (LYP) steel was adopted as the shear web plate of the steel plate shear wall. A total of two specimens with same geometric configuration but different loading procedures were designed and tested under the cyclic loading. The stiffness degradation, ductility and energy dissipation characteristics of the LYP steel plate shear wall (LSPSW) were investigated. Furthermore, comparative studies of the cyclic test and FEM analysis were carried out to verify the accuracy of the FE model of the LSPSW and conduct geometrical configuration optimization in the future. The test results indicate that the newly-developed LSPSW has superior ductility and energy dissipation capacity, which confirm that it can be used as an effective lateral force resisting structure system in the future. The yield load and ultimate load of the LSPSW obtained through cyclic tests exceed 3000kN and 5000kN, respectively, which meets the initial design expectation. In addition, numerical analysis results agree well with the test results.
