NUMBER OF CABLE EFFECTS ON BUCKLING ANALYSIS OF CABLE STAYED BRIDGES

Cables instead of interval piers support cable-stayed bridges, and the bridge deck is subjected to strong axial forces due to the horizontal components of cable reaction. The structural behavior of a bridge deck becomes nonlinear because of the axial forces, large deflection, and nonlinear behavior of the cables and the large deformation of the pylons as well as their interactions. The locations and amplitude of axial forces acting on the bridge deck may depend on the number of cables. This paper investigates the stability analysis of cable-stayed bridges and considers cable-stayed bridges with geometry similar to those proposed earlier. A digital computer and numerical analysis are used to examine 2D finite element models in these bridges. The eigen buckling analysis has been applied to find the minimum critical loads of the cable-stayed bridges.
