Abstract (EN): The influence of the steel strain in the bond-slip response has been referred in recent literature, mainly for steel strains after the yield. This paper presents the formulation for a new FE interface element which performs the bond-slip response including the steel strains. The element developed consists in an orthotropic four node plane stress element, whose constitutive material laws were changed. In order to evaluate the accuracy of this element two 2D numerical models were applied. The results obtained from the models with this element showed the need for its use to achieve good results and the relevance of steel strain on bondslip response, specially in tension elements.
