Abstract
An innovative class of fiber-reinforced composites is represented by Fabric-Reinforced Cementitious Matrix (FRCM) systems, which are becoming broadly used as externally bonded strengthening of both concrete and masonry constructions. The key feature of FRCM systems is the replacement of a classical polymeric matrix with an inorganic matrix, making them particularly effective in retrofitting of masonry structures given their chemical, physical, and mechanical compatibility to the substrate. Several experimental investigations have been carried out so far, both at the scale of the composite material and of structural components, reaching an adequate level of knowledge for structural engineering applications. In this chapter, we provide a comprehensive review on the mechanical behavior of FRCM composites and their beneficial effects on the performance of retrofitted masonry walls subjected to gravity loads and earthquake actions. Important issues related to the experimental material characterization, mechanical modeling, and effectiveness of FRCM strengthening systems are highlighted.
