ABSTRACT
The analysis of the interface performance of the fiber-reinforced mortar (FRM) reinforcement and masonry substrate is a critical problem as it influences the effectiveness of the technique. The need to guarantee higher safety levels of masonry structures under both short and long term conditions, have led to the use of new materials and technologies, in conjunction or in place of traditional ones. The use of a Glass Fiber Reinforced Polymers mesh embedded in a mortar coating on both sides of masonry walls proved to be an effective and reliable strengthening technique. The masonry typology is a double-leaf wall made of two vertical stone leaves. In terms of mechanical expectations, this mortar should have a low enough stiffness to achieve the required ductility of the masonry vaults, in relation to the bonding, unlike the matrix mortar, the structural response of which is needed. Tensile test on the FRM materials was also performed in order to estimate the tensile behavior.
