“…The energy dissipation capacity of retrofitted columns is influenced by FRP jacket confinement stiffness (Promis et al 2009, Gu et al 2010, the axial load ratio (Ozbakkaloglu and Saatcioglu 2007, Gu et al 2010, Zhou et al 2013a) and the aspect ratio of the column section (Ozbakkaloglu and Saatcioglu 2007, Gu et al 2010, Bui et al 2015. The improvement of the strength and ductility capacity by using FRP wrapping the full height of columns is not in proportion with that contributed from FRP wrapping in the potential plastic hinge locations (Parvin and Brighton 2014).…”

“…It has also been shown that the application of a hybrid FRPmodified mortar strengthening system leads to better ductility but lower strength than the externally bonded FRP alone for both masonry and RC walls (Papanicolaou et al 2011, Todut et al 2015, Umair et al 2015, Bui et al 2015. Appropriate application of anchorage systems can allow the FRP to develop its ultimate tensile strength without premature debonding and this signficantly improves the strengthening efficiency (El-Sokkary and Galal 2013, Cruz-Noguez et al 2015, Todut et al 2015, Umair et al 2015.…”

Many concrete structures are vulnerable to extreme loadings such as accidental impact, terrorist attack and earthquake disasters. Retrofitting of existing concrete structures for enhanced performance under these loadings has been an important topic of research for a long time, especially since the 911 terrorist attack. Among the different retrofitting techniques, external bonding of fibre reinforced polymer (FRP) composites has been a popular one. This paper presents a brief review of recent research on FRP strengthened concrete structures under blast, impact, earthquake and cyclic loading.

“…To address the issue, fiber-reinforced polymer strips and textile-reinforced concrete (TRC) [17] were respectively used on masonry walls, and both of them were able to improve the lateral bearing capacity and dissipation energy. Besides, the walls strengthened using TRC exhibited an increase of 185% in ductility but lower (175%) lateral strength when compared with the walls strengthened using FRP strips.…”

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.

“…e application of fiber-reinforced polymer (FRP) for masonry structure retrofitting and repairing is an advanced technology due to its advantages of high strength, light weight, good durability, and convenient implementation [4,[9][10][11][12][13]. In general, the existing studies have demonstrated that the seismic performance, including the seismic shear bearing capacity, the ductility, and the energy dissipation, of masonry structures can be significantly improved by bonding FRP composites [4,[14][15][16][17][18]. However, most of the previous studies focused on the FRP strengthened undamaged URM walls.…”

FRP composites have been used for strengthening RC and masonry structures for decades. However, the researches on repairing multistorey masonry structures using FRP grids were relative less. In the present paper, an experimental study on the seismic performance of multistorey masonry structure with openings repaired with CFRP grid is introduced. Specifically, a 1/3-scale three-floor masonry wall with window openings was tested under quasistatic action to simulate the seismic damages. The damaged masonry wall was then repaired by externally bonding CFRP grids to the areas where the cracks intensively occurred. The repaired masonry wall was retested under the same loading to investigate the seismic resistance and assess the recovery attributed from the CFRP grid repairing. The findings of this study showed that CFRP grid repairing could effectively postpone or even prevent the occurrence and development of cracking. The seismic resistance of the masonry, including shear capacity, energy dissipation capacity, deformability, stiffness degradation, and ductility, was restored. The application of CFRP grid may shift the failure mechanism of the multistorey masonry wall. The recommendation of repair scheme for the similar structures was also proposed in accordance with the findings of the present work.
