Abstract:
Hybrid box girders comprising prestressing steel, concrete flanges, and corrugated steel webs have been constructed in France and Japan, but remain relatively unknown in the U.S. The corrugated webs allow the minimum web thickness to be based on the allowable shear stress of steel, without the need for expensive stiffeners. The webs also don’t carry axial stresses due to prestressing, reducing the amount of required prestressing steel. In this article, the authors present a step-by-step analysis of an example girder.
