| | Summary: |
| | In this paper a unified frame for quasi-static and dynamic inelastic buckling and ultimate strength of uniformly compressed longitudinally stiffened plate girders is presented. The finite strip method is used in structural analysis. The nonlinear behavior of the material is modelled using the rheological-dynamical theory. According to this theory, a very complicated nonlinear problem in the inelastic range of strains is solved as a simple linear dynamic one. The orthotropic constitutive relations for inelastic buckling and a new modulus iterative method for the solution of nonlinear equations are derived in previous papers and the extensive numerical application is presented here. |
