| Abstract: | In this paper, a finite element method for elastic and inelastic lateralstability analysis of truss bridges has been presented, according to the practicaltheory of bending and torsion of trusses proposed by Li Guohao. After analysingthe elastic and inelastic stability of truss bridges, some approximate formulaefor the inelastic stability analysis have been proposed. In order to make sure of the reliability of the presented methods in thispaper, the results obtained have been checked by the finite element methodof space bar system. It shows that the presented methods have good accuracy. |
