In order to study the shear resistance of cold-formed steel wall with openings, a numerical model of the specimen for cold-formed steel wall with openings shear test was established using Opensees software, which was used to simulate its shear resistance under cyclic loading. On this basis, the parameters of the factors affecting the shear resistance of cold-formed steel wall with openings were analyzed. The results show that the contribution of the coupling beam to the shear performance of the whole wall is reduced with the increase of the span-depth ratio of coupling beam. When span-depth ratio of the coupling beam is greater than 5, the contribution of the coupling beam to the shear resistance of the wall is ignored. The ratio of opening to wall and the ratio of window to wall have a great influence on the shear resistance of cold-formed steel wall with openings, and the influence of each factor on the shear performance of the cold-formed steel wall with traditional side column is greater than that of the cold-formed steel wall with reinforced end studs. The stiffness of the side column has little effect on the shear resistance of the cold-formed steel wall with openings.
