The purpose of this article is to confirm an accuracy of Cohesive Zone Model (CZM) implemented in Ansys for modelling concrete beams strengthened with fiber reinforced polymer (FRP) tapes. Only mode II of debonding was taken into account, which is sufficient for a case of bent beam strengthened with FRP tape glued to its bottom. Results show satisfying coincidence of used model with experimental data and therefore confirm usefulness of CZM for solving the above mentioned problems.
