“…[3][4][5] 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, [6][7][8] 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 Discussion on this paper must be submitted within two months of the print publication. The discussion will then be published in print, along with the authors' closure, if any, approximately nine months after the print publication.…”

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.

“…One such method involves the use of Fiber Reinforced Polymer (FRP) composites such as carbon & glass FRP. Studies have shown that FRP reinforcements could be easily attached onto the masonry wall, thereby increasing its out-of-plane resistance significantly [2][3][4][5][6][7]. However, although FRP-strengthened masonry walls usually have substantial deformation capacity, final failure is often sudden and occurs without much warning.…”

Masonry has a widespread use in the construction of the buildings even in reinforced concrete or steel frames. Past earthquakes have demonstrated the vulnerability of masonry infills resulted in the human life losses and economic costs. Recently innovative strengthening techniques such as Textile Reinforced Mortar technique (TRM) is used for enhancing the seismic response of the infills. Different procedures were suggested to enhance the bond between rendering mortar of the TRM technique and infilled frame to prevent its detachment. In this study commercial glass fiber shear connectors were used for connecting the TRM layer to the infilled frame and their response were investigated by testing the samples in the in-plane direction. The quasi static in-plane test was performed cyclically on two specimens; one without strengthening layer and another strengthened with commercial textile meshes. The results showed that TRM technique enhances the in-plane response of the infilled frames but the effectiveness of the shear connectors could be improved using proper materials.
