Paper Title:
Assesment of Proposed Models for Determining Allowable FRP Tensile Strain for Mitigation of Debonding Failure in FRP-Strengthened RC Beams
  Abstract

intermediate crack-induced debondingis one of the most dominant failure modes in FRP-strengthened RC beams. Different code models or provisions have been proposed to mitigateintermediate crack-induced debondingfailure.However, these code models or provisions cannot mitigate this failure mode properly. Recently, mew models have been proposed.Out of all the existing proposed models, five typical ones are investigated in the current study. These main available proposed models for mitigating debonding failure of externally bonded fiber reinforced polymer composites appliedto concrete is evaluated based on data obtained from experimental programs. It is shown that all the evaluated proposed models exhibit a high level of dispersion, they are not suitable for limiting the allowable tensile strain at the initiation of debondingof FRP laminates.
