Lateral Torsional Buckling of Long Span Suspension Bridge: Geometrically Nonlinear Analysis Under Wind Load

SIMULIA's picture

There are plans of constructing bridges longer span like Messina strait bridge. This
trend causes the necessity of discussing on the problems of instability analysis such as lateraltorsional buckling. However, lateral torsional buckling analysis of long span bridge is not
sufficiently taken yet. For that reason, we apply the Abaqus/Standard to solve the high nonlinear problem. The analysis object is Akashi-kaikyo Bridge which is the longest bridge in the world. This paper presents how to analyze the lateral-torsional buckling of long span bridge applying wind load.
