A FINITE ELEMENT METHOD FOR ANALYZING THE LATERAL STABILITY OF A TRUSS BRIDGE WITH INCLINED PORTALS

The inclined portal panel of a truss bridge is considered as a substructure in this paper. The generalized stiffness matrix and geometric stiffness matrix of the substructure can be transformed linearly by using a buckling mode matrix of not full rank. The beam segments between portals are separated into generalized beam elements. The geometric relationship between the generalized displacements of the substructures and their adjacent beam segment elements is analysed. Thus, a finite element method of substructures and beam segment elements for analyzing the lateral stability of the truss bridge with inclined portals is obtained. This method is verified by comparing it with other known methods.
