Abstract:

This research addresses the application of high-strength reinforcing steel in Texas bridge construction. The project involved experimental and analytical work to evaluate the effectiveness of current design recommendations for high-strength reinforcing steel in various bridge structural components. These components include spliced beam, CIP-PCP deck, prestressed girder, bent cap, and footing. Significant findings include the validation of the tension lap splice length equation, the effectiveness of minimum web reinforcement requirements, and the influence of reducing the reinforcement quantities by replacing normal- strength steel with high-strength steel. Structural performance, including load-carrying capacity and crack control, was comparable compared to that achieved with normal-strength steel. The project provided design recommendations for integrating high-strength steel into various bridge components. This work offers valuable insights and guidelines for both the practical application and theoretical understanding of high-strength steel in Texas bridge construction.
