“…Therefore, basalt FRP (BFRP) composites are considered as feasible and sustainable alternatives to conventional FRP composites for future strengthening applications of RC structures. However, very limited research has been conducted in the literature on the efficiency of BFRP composites as a strengthening material to enhance the structural performance of deficient RC structures [38][39][40][41][42].…”

“…In recent years, with the increasing demand for masonry structure reinforcement, multiple techniques and products have become available to improve the seismic performance of masonry structures. For example, Santa‐Maria H et al, repaired cracked masonry walls with external fiber‐reinforced polymer (FRP), which could avoid the brittle failure mode, effectively restrain the development of existing cracks and enhance the seismic performance of masonry walls. The strain‐hardening characteristic of engineered cementitious composites (ECC) makes it an ideal material for earthquake strengthening of unreinforced masonry walls.…”

Brick cavity wall structures are widely distributed in southeastern China; however, their integrity and seismic behavior are extremely poor. To solve this problem, a new technique is proposed to enhance the seismic behavior of brick cavity walls using steel fiber reactive powder concrete (SFRPC) overlays. Two unreinforced cavity walls and four cavity walls strengthened with SFRPC overlays (applied over the entire wall surface) were tested under cyclic loading. In this study, the damage and failure modes of the specimens were analyzed in terms of the load displacement curves; furthermore, a comparative investigation was performed considering the load capacity, ductility, stiffness degradation, and energy dissipation capacity to demonstrate the merits of brick cavity walls strengthened with SFRPC overlays. The effect of strengthening using different thicknesses of reinforcement was investigated. In addition, damage analyses of the walls were performed based on the modified Park–Ang damage assessment model.

“…If sufficient FRP strengthening is applied, the failure can change from a shear dominant mode to a flexural dominant mode. Note that the FRP strengthening would not make a significant difference in the initial stiffness of walls (Zhou et al 2013b, 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.
