Research Abstract

Abstract The external bonding of fibre-reinforced polymer (FRP) sheets to reinforced
concrete (RC) structures has emerged as a popular method of strengthening. With this
strengthening method, the stress transfer performance of the FRP-to-concrete interface is of
crucial importance. Indeed, a number of failure modes associated with FRP strengthened
RC members are directly caused by debonding of the FRP from the concrete. The motivation
for this work is the fact that, although there is a large amount of experimental data
