Abstract:Precast, pretensioned concrete girders are extensively used in bridge engineering to prevent damage to concrete girders, such as the loss of prestress and the corrosion of strands. Existing studies of the mechanical performance and failure characteristics of bridge girders had shortcomings, resulting in potential safety hazards. This study conducted a full-scale model experiment and theoretical analysis of the bending performance of a 35-m long precast, pretensioned concrete I-girder with pretensioned double b… Show more
