The in-plane shear behavior of masonry panels strengthened with Fiber Reinforced Cementitious Matrices (FRCM) or Steel Reinforced Grouts (SRG) is investigated in this research in order to propose an improved analytical approach able to predict the maximum capacity. With this purpose, a dedicated experimental campaign is developed through the execution of diagonal compression tests. Experimental outcomes highlight the crucial role of the mortar matrix in enhancing the shear capacity of the masonry panels. The careful analysis of the different contributions during the tests allows the development of predictive formulas taking into account the role of the matrix and of the cracked masonry.

Abstract
The in-plane shear behavior of masonry panels strengthened with Fiber Reinforced Cementitious Matrices (FRCM) or Steel Reinforced Grouts (SRG) is investigated in this research in order to propose an improved analytical approach able to predict the maximum capacity. With this purpose, a dedicated experimental campaign is developed through the execution of diagonal compression tests. Experimental outcomes highlight the crucial role of the mortar matrix in enhancing the shear capacity of the masonry panels. The careful analysis of the different contributions during the tests allows the development of predictive formulas taking into account the role of the matrix and of the cracked masonry.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
