Özet

The strengthening of masonry structures is nowadays performed by means of High-strength fibers embedded in inorganic matrix (Fiber Reinforced Cementitious Mortar materials, FRCM). In such materials lime or cement-based matrix is used instead of epoxy adhesive to reduce debonding issues between substrate and matrix, however some sliding phenomena and cohesive failures between fibers and the matrix mortar can occur. The main aim of this research is to examine the impact on the FRCM efficiency of the mechanical properties of fiber and matrix and potential geometrical defects, which are possible in real field applications. Discussion is based on the predictions obtained through an analytical model recently developed by the authors to investigate the local effects of adherence that affect the mechanical behaviour of FRCMs.
