“…The Reticulatus method was typically applied for irregular stone masonry Corradi et al 2016), when the fair-face aspect needs to be preserved. In addition, there are applications of using only high strength cementitious mortars/plasters/matrixes (CP) on masonry surface to strengthen against shear effects Najafgholipour et al 2018). Subsequently, in this paper, an attempt was made to analyse the effectiveness of different strengthening solutions.…”

Masonry often requires strengthening to withstand against extreme actions such as earthquakes, cyclones and ooding. Recently, new solutions have been developed to strengthen masonry, such as Fabric Reinforced Cementitious Matrixes (FRCM) and Fibre Reinforced Polymers (FRP). However, other strengthening systems such as Welded Wire Meshing (WWM), Reticulatus and Plastering with Cementitious matrixes/mortar (CP) have been also practiced, conversely no systematic design guidelines are available for these methods. In this study, an attempt has been made to establish rational design approaches to predict the shear resistance of WWM, Reticulatus and CP strengthening systems. Three sets of experimental database have been developed for design veri cation. The effectiveness of these strengthening methods was appraised by comparing their structural performances. The available formulations to predict the shear resistance of unreinforced masonry (URM) and CP strengthened masonry were assessed against the established database, and suitable modi cations were proposed to effectively account the contribution of cementitious matrix. A uni ed approach to estimate the shear strength was proposed based on the contribution of URM, CP and reinforcements. The design approach is shown to conservatively predict the shear strength of reinforced masonry.

“…It was difficult to embed bolts in the masonry wall without massively shattering the bricks and mortar joints. External application of coating, such as engineered cementitious composites (ECC) (Dehghani et al, 2015;Lin et al, 2013;Yu et al, 2018b) and steel fiber-reinforced concrete (SFRC) (Najafgholipour et al, 2018), were also proposed as a retrofitting solution for masonry walls. The composite overlay system was found to be effective in improving the seismic performance of masonry member.…”

An experimental study was conducted to investigate the seismic performance of masonry walls strengthened using hybrid fiber-reinforced reactive powder concrete (HyFRRPC) as a coating. The proposed reinforcement technique was employed to improve the overall strength and structural integrity of the confined masonry wall. In order to guarantee the composite action between the masonry substrate and the coating material, material tests were conducted to achieve an optimal mixture for the HyFRRPC. Then, six full-scaled confined masonry specimens strengthened by HyFRRPCs with varied strengthening configurations were tested under in-plane quasi-static horizontal loading. The test and analysis results indicated that the proposed HyFRRPC-strengthening technique can effectively improve the lateral carrying capacity, displacement ductility, and energy dissipation capacity of masonry walls, and provide an optimal reinforcement. Finally, a simplified analytical model was also proposed for practical application.
