“…For all the aforementioned technologies, the composite action mechanism between the masonry substrate and the reinforcing overlay seems to be similar. As such, the performance of the bolted side-plated members (Li, 2013;Li et al, 2017b;Lo et al, 2014;Xu et al, 2017) is mainly controlled by the extent of partial interaction at the concrete-steel interface. In the same way, the composite action of FRP (Gao et al, 2015;Witzany et al, 2014) can only be effectively activated when satisfactory interfacial strains were induced by transverse deformation of the compressed masonry.…”

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.

“…However, the bolted steel plates were prone to fail in local buckling and thus cannot be introduced to the strengthening of masonry walls [9]. Although additional transverse stiffeners were found to be able to restrain the local buckling phenomenon to some extent [10,11], they exerted no significant influence on improving the overall strengthening performance. e effectiveness of fiber-reinforced polymer technique for reinforced concrete members has been profoundly investigated [12][13][14].…”

Masonry structures without effective reinforcement are vulnerable to seismic excitation. An innovative strengthening technique was proposed for damaged and undamaged masonry walls. Six confined masonry units with two aspect ratios were tested under in-plane lateral cyclic loading, which consisted of two control walls, two original walls strengthened with reactive powder concrete (RPC-1), and two damaged walls repaired with RPC (RPC-2). The results of the specimens retrofitted with RPC demonstrated that the proposed technique significantly enhanced the seismic performance of masonry walls in terms of lateral strength, ductility, and energy dissipation. Furthermore, the two repaired specimens had a better distributed cracking pattern than the two strengthened specimens. The analysis of the results leads to a better understanding of the effect and mechanism of RPC seismic retrofitting for confined masonry walls.

“…Although the BSP technique was found to be an effective way to strengthen RC beams [26][27][28][29][30][31], existing related studies, especially those related to shear strengthening, are still far from sufficient when compared to those on the bending behavior of BSP beams. Thus, it is of great significance for researchers and engineers to establish an analytical system and design scheme to predict the shear performance of BSP beams in practical applications.…”

Reinforced concrete (RC) beams may need to be strengthened because of material deterioration, structure aging, change of building function, defective design, and the decrease of structural reliability caused by accidental disasters such as earthquake and fire. Thus, the retrofitting of RC beams has become a crucial problem, especially for the old buildings constructed before 1980 in mainland China. A variety of studies have proven that the bolted side-plating (BSP) method is feasible and effective for rehabilitating RC beams in existing buildings and infrastructures. The aim of this paper is mainly to review the previous studies conducted by the authors on the shear performance of reinforced concrete (RC) beams retrofitted using the BSP technique, including experimental, theoretical, and numerical studies.
