| Abstract: | Based on the theory of nonlinear finite element of plate and shell,a finite element method of elasto-plastic flexural-torsional buckling of steel members under cyclic loading was presented,and a nonlinear analysis program was complied.By comparing the calculating result with other analysis,the effecetiveness of this method may be verified.The results indicate that the method is accruate for analyzing the elasto-plastic flexural-torsional buckling of steel member under cyclic loading. |
