APPLICATIONS OF HIGH STRENGTH CONCRETE FOR HIGHWAY BRIDGES

This report summarizes the results of a study to determine the potential for high strength concrete in highway bridges. Current data and applications are reviewed and related to AASHTO specifications. Conceptual designs are developed to explore the potential for such possibilities as increased span lengths; wider girder spacings; reduced cross-sectional areas of compression members; and thinner plates for segmental construction, arch bridge members and piers. The capacity of thin concrete plates in buckling is studied. Comprehensive interaction diagrams developed through a computer program are used to determine the controlling factor for square hollow piers made with thin plates of high strength concrete. The diagrams were confirmed by laboratory load tests under varying eccentricities. Also presented are code proposals and concepts for the more rapid adaptation of high strength concrete for use in highway bridges.
