Strengthening with advanced composites
Design of externally bonded reinforcements with FRCM systems
Fabric-reinforced cementitious matrix (FRCM) systems for repairing and strengthening masonry structures are an alternative to traditional techniques such as fiber-reinforced polymers (FRPs), steel plate bonding, section enlargement, and external post-tensioning. FRCM are composite materials consisting of a sequence of one or more layers of inorganic (i.e., typically, cement or lime-based) matrix reinforced with dry […]

Seismic retrofitting with Textile Reinforced Mortars
Description Masonry walls are particularly vulnerable against out-of-plane seismic actions. Steel tie-bars can prevent their overturning, but collapse may take place also by bending, leaf separation or disaggregation. Textile Reinforced Mortar (TRM) composites, recently developed and made available in the marked, can be integrated with traditional techniques in compliance with the preservation criteria […]

Seismic retrofitting with Composite Reinforced Mortar
Description Recent earthquakes have dramatically shown the seismic vulnerability of unreinforced masonry structures, which represent a significant proportion of the European built heritage. Despite the importance of minimizing the risks associated with earthquake induced damage on the building stock and the studies that have been carried out to date to tackle this challenging […]
