ABSTRACT
An experimental investigation was conducted at the Centre for Effective Design of Structures at McMaster University to study the influence of fibre-reinforced polymer (FRP) laminates on the sliding shear resistance of unreinforced masonry (URM). This paper presents the results from the initial phase of this investigation which involved selection of an appropriate test specimen shape. Thirty-six URM assemblages were tested in direct shear, and of these fourteen were retrofitted with an FRP laminate. Thus, the only test parameters were the shape of the test specimen and the presence of the FRP retrofit. The results showed that the application of FRP laminates on URM greatly improved the shear slip strength, deformation characteristics, and post-peak response. The retrofitted specimens reached shear slip strengths ranging from 3.2 to 7.7 times that of their non-retrofitted counterparts.
