ABSTRACT

Fiber Reinforced Cementitious Matrix (FRCM) reinforcement composed of a glass fiber grid embedded inside a lime mortar. Reinforcement was placed only on the side that would be subject to traction during the out-of-plane test, since the main interest lays on the mechanical behavior of FRCM under traction. An experimental campaign, devoted to the investigation of the out-of-plane behavior of masonry walls reinforced with FRCM composite materials. Longitudinal deformations of the FRCM surface along its centerline were measured by using a series of seven strain gauges properly spaced. In case of debonding or delamination within the mortar layer, FRCM contribution could be estimated by using some predictive formulas contained inside the Italian Guidelines for the design and construction of externally bonded Fiber Reinforced Polymers systems. If delamination within the mortar layer occurs instead of debonding, a modified formulation is needed, by considering mortar mechanical properties rather than brick compressive and tensile strength.
