Abstract: The tensile member of angle steel is a kind of common component for steel structures. It often occurs local deformation in practical project because of mechanical collision or accidents. There are a lot of domestic research on the bearing capacity of tensile member of single angle. However, when it comes to the double equal-angle steel component with local concave-convex deformation, there is still a lack of research of its bearing capacity in related specifications. With the verified method of finite element simulation using ABAQUS software, a simulation study on three types of tensile members of double equal-angle was conducted. As a result, the reduction coefficient of tensile capacity with different local deformations was deduced, which could be used to check the tensile capacity of tensile members of double angle with different surface defects.
