Ductility of non-compact steel bridge beams

Abstract

The objective of this study is to investigate the ductility of simply supported composite rolled beams that satisfy all compactness requirements except the one pertaining to ductility. Typical sections in positive bending are analyzed for a profile of curvature. A parametric study is carried out to investigate the effect of variation in some design variables on ductility. These design variables include the grade of structural steel, concrete strength, deck dimensions and reinforcement, depth of steel beam, and presence of a cover plate.
