“…Many studies at various levels have been carried out to investigate the in-plane performance of masonry panels strengthened by composites and made of: concrete blocks or bricks [3][4][5][6][7][8], calcareous stones and bricks [9][10][11]. In the present paper, a comprehensive experimental research on full-scale tuff masonry panels strengthened with FRP and subjected to in-plane loading is presented.…”

“…When FRP systems are used with concrete, whether internal or external reinforcing, the fibres and matrix will be exposed to the high alkaline environment present in the concrete. This environment is known to attack some glass in FRP composites (Christensen 1996). Katsuki and Uomoto tested glass, aramid, and carbon FRP exposed to NaOH solution (Katsuki 1995).…”

New fillers confined with Glass Fiber Reinforced Polymer (GFRP) circular tubes provide a suitable structural member for a variety of applications including piles, columns and provide very high strength in compression. The filament architecture plays an important role in the properties of the tube to provide the confinement to the filler. Apart from providing confinement, GFRP tubes also serve as formwork and protect filler from deterioration. In this paper, a preliminary development of polymer based filler materials for GFRP tubular connector is discussed as a substitute of conventional concrete fillers. Sample trial mixes were considered based on several weight percentages of polymer resin, fly ash and sand. Material parameters such as compressive strength, stiffness, shrinkage and gel time were achieved from the experimental investigation. It has been found that most polymer based trial mixed fillers have high compressive strength and considerable plastic region with more than 10% strain. However, the behavior of fillers with GFRP confinement under different loading conditions is yet to be fully understood.

“…Potential applications include strengthening for a change in lateral loads (wind or seismic); repair of inadequate construction; or possibly as an alternative reinforcing method for new construction. Numerous investigators have explored the potential use of FRP on concrete (Albert et al 1998, Hamilton et al 1999, Hartley et al 1996 and clay (Christensen et al 1996, Dolan 1998, Ehsani and Saadatmanesh 1996, Ehsani et al 1999, Ghobarah and Baumber 1992, Hamilton and Dolan 1998, Luciano and Sacco 1998, Triantafillou 1998 masonry. One reason for the interest is that traditional strengthening techniques can be labor intensive, add considerable mass, and cause significant impact on the occupant, all resulting in very high and likely prohibitive costs.…”

Research on the use of fiber-reinforced polymer (FRP) composites for strengthening of unreinforced or inadequately reinforced hollow concrete masonry is covered in this paper. Quasi-static shear wall tests were conducted on unreinforced concrete masonry specimens that had been strengthened with unidirectional glass fiber strips applied to the surface of the masonry using a two-part epoxy to form a surface-bonded GFRP composite. The strips were strategically placed to improve both flexural and shear strength in the in-plane direction. The GFRP composite system was combined with conventional structural steel and reinforcing steel connections that were designed to yield before the composite ruptured, resulting in a ductile failure mode under cyclic testing. The drift capacities of the tested specimens ranged from 0.6% to 1.7%.
