| Abstract: | Based on the finite element method, the interactive buckling of straight H-section steel beams used in portal frame structures are analyzed by ANSYS, in which geometric non-linearity and material non-linearity are considered and shell element is adopted. According to the load-deflection curves obtained, the effect of residual stress on the interactive buckling of straight H-section steel beams are discussed. Some valuable conclusions are drawn. |
| Keywords: | H-section beam with thin web interactive buckling residual stress |
