Abstract: In this paper a numerical and experimental investigation of masonry arches is developed with an analysis of the effects of strengthening by means of advanced composite materials. More precisely, the focus of the analysis concerns the effects on the strength and stiffness improvement of damaged solid clay brick masonry arches by strengthening with carbon fibre reinforced plastic (CFRP). The masonry arch is modelled by assuming a no-tension material law. Moreover, the interface between mortar and bricks are modelled by assuming a unilateral contact behaviour. A 3D finite element model of the structure is developed accounting for the effective geometry of the brick-mortar components of the masonry arch and of the reinforcement layer. An experimental campaign was developed aimed to study the behaviour of damaged solid clay brick masonry arches strengthened with carbon fibre reinforced plastic.

Keywords: masonry arch; modelling; experimentation.
