Description
This study investigates the accuracy and reliability of the existing design models for shears-strengthened reinforced concrete (RC) beams with near-surface mounted (NSM) fibre-reinforce polymer (FRP) rods and laminates. Separate statistical and reliability-based studies have been conducted on the predicted shear contributions of NSM FRP materials in the strengthened beams using seven existing design models. To assess the accuracy and reliability of these models, the predictions were compared with the experimental results on 112 test specimens from 24 studies. A special attention is paid to the available NSM bond models employed in developing the shear strength. The results of this study can be used for standard committees to choose the most precise and reliable models for their corresponding design standard code or guidelines.
