Analysis of Mesoscopic Interfacial Mechanics of RC Beams Strengthened with FRP
Concrete is assumed as a three-phase composite material composed by aggregate, mortar matrix and the bond layer between them in mesoscopic. The damage constitutive relationships of the composed materials are determined. A local meso-model of reinforced concrete (RC) beams strengthened with hybrid FRP was established to investigate the crack propagation and failure modes. The results show that the deformation, damage and failure of the concrete occurred near the ends of the interface.
