Abstract

Fiber reinforced polymers (FRP) have been increasingly popular over the past decades in civil engineering, even for the purpose of strengthening unreinforced brickwork. The primary aim of utilizing FRP on masonry walls is to enhance their strength and displacements. To strengthen cross walls and increase tensile capacity during an earthquake, it may be convenient to use externally bonded (EB) Glass-FRP strips. This strengthening system is affected by loss of bond with delamination of GFRP strips from surface of bricks.

The investigation’s findings regarding the bond between GFRP strips and modern brickwork masonry surfaces are presented in this paper. Pull-push shear tests were performed on brickwork specimens with different thickness of bed mortar joints strengthened by EB-GFRP strips. Failure’s modes are described with shear-slip laws and energy fracture values.
