The present paper is aimed to shed new light on the role played by some parameters (such as the amount of steel rebar, yielding stress, FRP-to-Rebar ratio, load pattern) that are not yet included in the most accepted formulae for evaluating the maximum axial strain developed in FRP at debonding. The above mentioned parameters, along with other ones already accepted in the current formulations (namely, fracture energy and FRP specific axial strain), have to be used for determining a more accurate formulation for preventing debonding failure.

Abstract
The present paper is aimed to shed new light on the role played by some parameters (such as the amount of steel rebar, yielding stress, FRP-to-Rebar ratio, load pattern) that are not yet included in the most accepted formulae for evaluating the maximum axial strain developed in FRP at debonding. The above mentioned parameters, along with other ones already accepted in the current formulations (namely, fracture energy and FRP specific axial strain), have to be used for determining a more accurate formulation for preventing debonding failure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
