Early-Age Deck Cracking from Asymmetric Thermal Behavior in Skewed Adjacent Box Beam Bridges

This study investigates the causes of early-age deck cracking for skewed composite adjacent box beam bridges with integral abutments. It hypothesizes that cracking is attributed to (1) asymmetric thermal movements in a skewed deck and (2) thermal restraints from an integral abutment design, as well as box beams and post-tensioned tie rods. To verify this hypothesis, a bridge in Ohio was instrumented for measuring temperature and strain. The...
