【Abstract】 A variable cross-section ribbed double steel plate composite shear wall steel beam node model was established using ABAQUS finite element software. The rationality and precision of numerical simulation are proved by comparing with experimental data. and phenomena. The basic model of the variable cross section ribbed double-leg double steel plate composite shear wall has been designed, and its finite element model was established to obtain the failure mechanism under low cycle repeated action. Analysis is made on the frame curve, ductility, energy dissipation, and the effect of the axial compression ratio and the coupling ratio on the seismic performance. Research has shown that this structure has good seismic performance, high bearing capacity, good ductility, and high energy dissipation capacity. A calculation formula for the ultimate bending bearing capacity of a variable cross-section ribbed double leg double steel plate composite shear wall has been derived, and the theoretical results are in good agreement with the results of FEM.更多还原
