Abstract

In the current design procedure for recent continuous composite steel-concrete bridges at an internal support under negative bending moment, the lateral torsional buckling theory is applied to evaluate an allowable stress in disregard of lateral restraint of top flange by a concrete slab. In actual continuous composite bridges, instead of the lateral torsional buckling, restrained distortional buckling may occur. This paper proposes a design procedure for the restrained distortional buckling of continuous composite girders under negative bending moment.
