| Abstract: | Based on the theory proposed in reference, a mechanical model of arch portal panel for analysing lateral stability is developed and a finite beam element method for inelastic lateral buckling analysis of arch-truss bridges is presented. This method is examined by a plexiglass model test and checked against the finite element method of space bar system. The results show that the accuracy of the proposed method is quite satisfactory. In addition, the characteristics of the lateral stability of arch-truss bridges are discussed. Finally, an approximate method for calculating inelastic lateral buckling loads is suggested. |
