An Experimental Analysis of the Mechanical Behaviour of Anchored Cfrp-to-Masonry Reinforcements Loaded by Out-of-Plane Actions

Carbon Fibers Reinforced Composite (CFRP) materials are widely used for structural rehabilitation and retrofitting of both masonry and concrete structures. Recent studies published in the literature are devoted to the analysis of novel methods to increase CFRP-to-substrate bond capacity. Among these, spike anchors demonstrated to be able to effectively increase both strength and ductility of CFRP reinforcement sheets. Since most of the literature in this field refers to CFRPto-masonry reinforcements loaded by in plane actions, the experimental research described in this paper is devoted to the analysis of the effectiveness of spike anchors in CFRP reinforcements bonded to masonry structural elements loaded by out-of-plane actions.
