At present,the common design software can only define the beam-column joint as fully hinged or completely rigid, and the nonlinear stiffness of the node cannot be directly specified,and the overall analysis of the beam-column semi-rigid joint steel structure cannot be carried out quickly. In order to improve the design efficiency,based on the overall analysis results of the general finite element software ANSYS,the steel structure design software Midas gen and 3D3S were selected to simulate the semi-rigid connection characteristics of the beam-column joints by establishing the elastic connection and giving it nonlinear stiffness,and the nonlinear analysis of a single three-layer frame structure was carried out,and the corresponding correction method was proposed. The corrected results show that the calculation results of Midas Gen and 3D3S are small and the ANSYS error is small using the method provided in this paper, which can be used for structural design. At the same time,this method can be used to quickly modify and check the beam cross-section,complete the appropriate internal force amplitude adjustment,and improve the structural economy
