“…The lower increase in shear strength for the singlesided retrofitted specimens was attributed to the unrestrained boundary conditions of the diagonal compression tests, as these specimens showed out-of-plane bending behaviour. This out-of-plane bending during the diagonal compression testing of single-sided FRCM retrofitted specimens, caused by the eccentric stiffness resulting from the application of the reinforcement on a single side, was also reported in other researches [16,17]. Shabdin, Zargaran and Attari [16] tested medium-scale URM walls strengthened with FRCM under diagonal compression in order to consider the effect of strengthening system on the behavior of brick walls.…”

“…It (18) With the absence of anchors (F v,r = 0), the maximum horizontal load resistance F Rh follows from Eq. (16). This can be used to determine the added value of the anchors for the moment resistance of the wall.…”

“…Past experimental programs assessing innovative strengthening systems based on cementitious mortar matrices, highlighted a significant improvement in both in-plane and/or out-of-plane lateral strengths of masonry walls [6,7,10,[14][15][16][17][18][19][20][21][22]. Based on the response of medium-scale clay brick shear walls, beam-column type walls and beam type walls subjected to cyclic in-plane loading, Papanicolaou, Triantafillou, Karlos and Papathanasiou [10] concluded that FRCM overlays provide a substantial gain in strength and deformability.…”

An experimental program was undertaken to assess the effectiveness of a new retrofit concept to improve the in-plane behavior of unreinforced clay brick walls by means of full-scale static-cyclic in-plane tests. The proposed seismic retrofit system combines two standalone retrofit measures for in-plane and out-of-plane strengthening of masonry walls. The inplane reinforcement consists of a single-sided carbon Fabric-Reinforced Cementitious Matrix (FRCM) overlay, and anchors embedded with a flexible adhesive in the masonry. The out-of-plane reinforcement, which consisted of deep mounted Carbon Fibre Reinforced Polymer (CFRP) strips embedded with a flexible adhesive in the masonry, was included in the study to investigate the possible degrading effects of the deep groove on the in-plane behavior. A total of nine full-scale reinforced masonry walls with three different geometries were tested under three different axial loads. None of the specimens showed shear failure at both the reinforced and the as-built side. Cracking predominantly occurred at the interface between the bottommost bed-joint and the foundation beam. The out-of-plane reinforcement did not affect the in-plane strength, as no vertical shear cracks occurred. Moreover, it was found that the anchors increased both the rocking and sliding resistance of the walls. An analytical model was proposed covering the rocking and sliding resistance of the reinforced walls, providing a good approximation of the experimentally obtained in-plane strengths. Additional pull-out experiments showed that the testing scenario where the tensile forces in the anchor were transferred to CFRP strip, provided a good approximation of the analytically determined anchorage strength.

“…TRMs, also known as fibre reinforced cementitious matrix (FRCM) [1], are innovative composites constituted of high-strength fibres (basalt, glass, steel) in the form of grids embedded into inorganic matrices, such as natural mortars or cements. Over the last decade, many experimental studies have been carried out to investigate the effectiveness of TRM composites in different load configurations, see for example [2][3][4][5][6][7][8][9][10]. Different design approaches are currently available for quantifying the strength of masonry walls externally reinforced by composite materials [2,8,11].…”

We report on experimental and numerical investigations of textile reinforced mortar (TRM) strengthening systems, an innovative solution for reinforcing historical masonry structures. The experimental campaign presented in this paper is original and concerns two commercial TRM applications to single-leaf clay masonry panels. The proposed FE modelling is based on a multiscale approach with the possibility of simulating bed joints sliding and TRM-reinforcement debonding. This last phenomenon is frequently reported in the experimental literature and it has been observed also in our experimental tests. The numerical model is applied to study the behaviour of TRM reinforced masonry panels under diagonal compression tests.
