The experimental investigation aims to analyse the efficiency of the FRP (Fiber Reinforced Polymer) strengthening technique in terms of in-plane behaviour of the reinforced masonry element. In particular ten masonry panel were realized with local stone (Lecce stone) and strengthened with two types of geometric configuration (grid and diagonal) of the BFRP (Basalt Fiber Reinforced Polymer) reinforcement. The eccentricity of the strengthening was also considered as variable parameter. The obtained experimental results in terms of strength, mechanisms of failure and ductility underlined the effectiveness of the technique for all analysed configurations in comparison with unreinforced masonry panels. In particular better performances were observed in terms of ductility in the case of FRP grid configuration while the diagonal reinforcement furnished the highest value of shear strength.

Abstract
The experimental investigation aims to analyse the efficiency of the FRP (Fiber Reinforced Polymer) strengthening technique in terms of in-plane behaviour of the reinforced masonry element. In particular ten masonry panel were realized with local stone (Lecce stone) and strengthened with two types of geometric configuration (grid and diagonal) of the BFRP (Basalt Fiber Reinforced Polymer) reinforcement. The eccentricity of the strengthening was also considered as variable parameter. The obtained experimental results in terms of strength, mechanisms of failure and ductility underlined the effectiveness of the technique for all analysed configurations in comparison with unreinforced masonry panels. In particular better performances were observed in terms of ductility in the case of FRP grid configuration while the diagonal reinforcement furnished the highest value of shear strength.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
