High-Strength Concrete Prestressed Bridge Girders: Long Term and FlexuralBehavior

摘要

Two long-span high-strength composite prestressed bridge girders were constructedto investigate their structural behavior and the adequacy of American Association of State Highway and Transportation Officials (AASHTO) 1993 provisions for their design. The scope of this research included investigation of prestress losses, transfer length, cyclic load response and ultimate flexural strength.
