Abstract:

In the past decade significant advances have been made in the field of high performance concretes (HPC). The next generation of concrete, ultra-high performance concrete (UHPC), exhibits exceptional tensile and compressive strength characteristics that make it well suited for use in highway bridge structures. Prestressed highway bridge girders were cast from this material and tested under flexure and shear loadings. These American Association of State Highway and Transportation Officials (AASHTO) Type II girders contained no mild steel reinforcement, forcing the UHPC and its internal passive fiber reinforcement to carry all secondary tensile forces within the girder. These tests demonstrated that UHPC can carry all shear forces normally demanded of a prestressed I-girder and can also significantly enhance the flexural capacity of the girder. Based on this research, a basic structural design philosophy for bridge I-girder design is proposed.
