Abstract
The paper concerns with the debonding analysis of reinforced concrete beams strengthened by a fibre Reinforced Cementitious Mortar system made with fabric meshes of PBO (short of Polypara-phenylene-benzo-bisthiazole) fibres disposed along two orthogonal directions externally bonded to concrete surfaces with a cement based mortar. Some PBO-FRCM strengthened reinforced concrete beams were tested varying the strengthening configuration. Experimental results were considered for a comparison with predictions of a non-linear numerical model developed for the debonding analysis of strengthened concrete structures. Obtained results give evidence of the influence of the PBO-FRCM configuration on the occurrence of debonding failure modes.
