Partial and Full Interaction Behaviour of CFRP Plated Steel Member Due to The Yielding of Steel

The reliability of the strengthening of Fibre Reinforced Polymer (FRP) to steel or concrete structures depends on the success of the stress transfer between the FRP plate and steel or concrete element. In order to simulate the stress transfer, a simple numerical approach was developed, employing the partial interaction theory. In this paper, the numerical method applying the partial interaction theory is used to evaluate the debonding of FRP plated steel member due to the yielding of steel. An accurate local bond-slip (-δ) model was adopted in the numerical procedure. A set of pull test specimen was tested to prove the existence of partial and full interaction regions along the bonded length. Comparison with the experimental and published results shows good correlations.
