BRACING OF STEEL-CONCRETE COMPOSITE BRIDGE DURING CASTING OF THE DECK

Mehri, Hassan LU and Crocetti, Roberto LU (2012) Nordic Steel Construction Conference 2012
Abstract
Trapezoidal cross sections are often used as main longitudinal load-bearing systems in steel-concrete composite bridges. A critical design stage for these girders occurs during casting of the bridge deck, when the non-composite steel section must support the entire construction load, including the wet concrete. A research work was undertaken to study lateral torsional buckling (LTB) capacity and stiffness requirements of U-shaped girders with focus on discrete torsional bracing and top lateral truss bracing, under uniform loading condition due to self-weight of structural system and wet concrete. Findings are then compared with the results obtained by previous research works and common code specifications.
