Experimental behaviour of full scale masonry columns confined with FRP or FRCM systems

In last decades, several experimental tests were carried out in order to investigate the effectiveness of strengthening systems by using FRP as a confinement technique of masonry columns. Recently, in order to solve problems related to the compatibility of FRPs with masonry members, a new technique based on the use of inorganic matrix rather than resins has been developed (FRCM-Fabric Reinforced Cementitious Matrix). In order to investigate the structural effectiveness of FRCM systems, an experimental program was carried out on full-scale masonry columns by means of uni-axial compression tests. In particular, the effectiveness of FRCM systems based on the use of A.R. glass fibre grid embedded in lime-based mortar with high mechanical properties has been investigated. Test programme, material mechanical properties, and test setup are herein presented along with the preliminary experimental results in terms of load and ductility capacity of a control and strengthened specimen. A preliminary comparison between the performance of FRP and the strengthening systems is also reported
