MODEL UNCERTAINTY OF EXTERNALLY BONDED FRP-TO-CONCRETE JOINTS

摘要：

　　This paper presents a study of the model factor ε 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 ε 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.
