Evaluation of the bond-dependent factors for CFRP bars used as structural reinforcement: a critical review

This study analyzes the precious data from the literature on bond strength between concrete and CFRP bars associated with the pullout test. In this regard, an overview of the pullout test and bond stress-slip model, along with a systematic analysis of characteristic bond strength behavior, were revi...
