In order to study the seismic performance of steel plate shear wall structures(weak axis con-nection)with partially encased concrete composite columns,a numerical simulation of one steel plate shear wall structure with H-shaped edge column and five steel plate shear wall structures with PEC column(weak axis connection)under cyclic loading was conducted using the finite element software ABAQUS.The stress distribution,failure mode,hysteretic curve,energy dissipation performance,skeleton curve,and stiffness degradation curve of the structure are obtained.Additionally,a test of a steel plate shear wall structure with a PEC column(weak axis connection)was performed to validate the finite element model.The analysis shows that in the steel plate shear wall structure(weak axis connection),taking the PEC col-umn as the edge frame column of the shear wall effectively restrains the steel plate shear wall after buck-ling,making it give full play to the post buckling performance,and significantly improving the lateral stiffness,bearing capacity,and energy dissipation performance of the whole structure.
