| Abstract: | Based on the elasto-plastic anisotropic damage constitutive modelof the constructional steel, the method of double nonlinear shell FEM is adopted to analyze the elasto-plastic stability of the steel Ⅰ beams under the action of cyclic loads, and the results comply with those obtained in the tests. The method with high precision can be widely used in analyzing the elasto-plastic stability of the steel members. |
