Abstract

An experimental program concerning the structural behaviour of anchored Carbon Fiber Reinforced Polymer (CFRP) externally applied reinforcements bonded to portions of masonry arches is described. Two different curvatures have been considered as well as two different positions of the reinforcement (intrados/extrados). The so-called Single Lap Shear Test Scheme was considered in the experimental program: the specimens were constrained at the upper and lower faces and were loaded by a force tangent to an end of the reinforcement. The experimental results allowed to evaluate the effectiveness of the anchored reinforcement with respect to its position (intrados/extrados) and to the curvature of the specimens. The contribute due to the anchor has been evaluated comparing the test results with a previous experimental program carried out on specimens having the same characteristics but reinforced by a CFRP sheet without anchor. The experimental outcomes showed that the curvature marginally affected the bond behaviour of the anchored reinforcements that, instead, was strongly influenced by the position of the reinforcement.
