| Abstract: | A synthetic discrete method is presented for the analysis of the inelastic stability of space steel frames. The method not only possesses the FEM advantages for discrete structures, but also reduces the unknowns in structural analysis. Numerical results show that this method can greatly reduce the time of computation and has satisfactory precision. In view of the aboveadvantages, this method can be used effectively in the analysis of the elastoplastic stability of space steel frames for the engineering design. |
