Abstract

This paper presents a study of the model factor Îµ for bond strength model of fiber reinforced polymer (FRP)-to-concrete joints, which is defined as the ratio of tested bond strength to the predicted result by the model. A total of 641 shear tests of externally-bonded FRP (EB-FRP) joints were collected to evaluate the statistics of Îµ and four frequently used models in literature were compared. It was found that the model factors of the models with a relatively high COV value (larger than 0.3) were not random, but heavily dependent on the input parameters.
