摘要:

The nonlinear finite element method (FEM) was used in the paper by using LS-DYNA software to numerically study the failure mechanism of light steel columns under fire and explosion. The constitutive model under the combined effects of fire and explosion was established, and the numerical simulation analysis of the columns under combined effects of fire and explosion was performed. The results showed that the failure modes of the mentioned columns were all bending shear failures. The deformation diagrams of the column under the blast and different temperatures, respectively, were proposed and this will provide a foundation for establishing the failure modes and the simplified calculation method. According to the relationship between rotation angles at the ends of the column and temperatures, the damage index of D was proposed in this paper for the evaluation of the damage level of the simulated light steel column
