ABSTRACT
This chapter presents the results of preliminary tests of several techniques with the aim of enabling near surface mounted fiber reinforced polymer (FRP) reinforcement on the external faces of unreinforced clay brick cavity walls to work under full reverse cyclic loading. It aims to investigate the behaviour of clay brick cavity walls that have been reinforced with near surface mounted FRP strips on only the external faces of the cavity walls. The test results confirmed that the use of FRP reinforcement in cavity masonry walls was able to significantly improve both the ultimate strength, and ductility of the walls in vertical bending. Application of mechanical anchors produced similar behaviour to the case of connection by standard wall ties. In solid unreinforced masonry walls, the surface treatments that provide tensile capacity to the wall have been shown to be very effective flexural retrofit techniques.
