Abstract

The use of high strength concrete in the fabrication and construction of prestressed concrete beam bridges can result in the increase of girder spacings for standard shapes, as well as the increase of span lengths. The increase of girder spacings corresponds to the reduction of the required number of girders. This study shows that the use of high strength concrete make prestressed concrete beam bridges the economical alternative to any other bridge types. Also, this study has the purpose of giving aids to design of prestressed concrete beam. To achieve this purpose this study provides the plots resulting from research on relationships between the concrete strength of prestressed concrete beam, girder spacing and the number of strands in various span lengths.
