| Abstract | The results of an experimental and numerical investigation involving unstrengthened reinforced concrete (RC) T-beams as well as precracked RC T-beams strengthened in shear with prestressed carbon fiber reinforced polymer (CFRP) straps are presented and discussed. The results provide insights into the influence of load history and beam depth on the structural behavior of both the unstrengthened and strengthened beams. The strengthened beams exhibited capacity enhancements of 21.6% to 46% compared to the equivalent unstrengthened beams, demonstrating the potential effectiveness of the prestressed CFRP strap system. Nonlinear finite element (FE) predictions, which incorporated the load history, reproduced the observed experimental behavior but either underestimated or overestimated the post-cracking stiffness of the beams and strap strain at higher load levels. These limitations were attributed to the concrete shear models used in the FE analyses. |
