Abstract EN
A modification method was proposed for near-surface mounted (NSM) fiber-reinforced polymer (FRP)-concrete bonded joints strength prediction models considering model uncertainty.
A database consisting of 246 test records was involved.
Three bonded joints strength prediction models for NSM FRP reinforcement system were selected for modification.
All the three selected models have model uncertainty factors associated with input design parameters.
Spearman correlation analysis was used to prove the systematic correlation of the model uncertainty factors.
For each model, a regression function f was established to eliminate the systematic nonrandom part of the model uncertainty factor.
Then, the model uncertainty factors could be described by random variables obeying logarithmic normal distribution.
A reliability analysis using the JC method was carried out to validate the practical significance and value of model modification.
This study improves the predictability of FRP NSM reinforcement systems and provides valuable references for model calibration in practical engineering.
