Abstract:As the hinge to transfer the internal force of the building structure, the special-shaped joint is an important guarantee for the safety of the structure to meet the stress requirements. In order to accurately restore the mechanical characteristics of special-shaped joints, a multi-scale nonlinear numerical simulation method is proposed for the ultimate bearing characteristics of special-shaped joints in steel structures. Considering geometric structure, material properties and other factors, a nonlinear finite element model of special-shaped joints in steel structure buildings is built. The loading process of special-shaped joints is simulated, and the mechanical mechanism of joints is analyzed at multi-scale. The ultimate bearing capacity of special-shaped joints is calculated from the aspects of shear resistance and bending resistance, and the numerical simulation results of the ultimate bearing characteristics of special-shaped joints are output. The results show that compared with traditional numerical simulation methods, the simulation error of the ultimate bearing capacity of the optimized design method has been reduced by 1.88N; The application of this method can effectively reduce the probability of instability of irregular nodes.

Keywords:steel structure building; special node; ultimate bearing characteristics; multi scale simulation; nonlinear numerical simulation;
