Abstract

Abstract

Nanhe bridge locates on Nanjing-Hangzhou highway. It is a simply supported, concrete filled steel tubular, tied-arch bridge with a span of 130 m.The bridge's 3-D finite element model of stability analysis was created by structural analysis program ANSYS based on considering its nonlinear stability influence factors. Its buckling modes were provided, its nonlinear solution method was discussed, the nonlinear stability calculation of the bridge was performed. The result shows that a plastic hinge is firstly developed at the arch springing, its stability collapse load is 3.5 times larger than the design load, which satisfies the requirement of the bridge stability.
