Abstract

This paper provides the results of a series of shear tests carried out on wall panels reinforced with two techniques by means of jacketing with GFRP (Glass Fiber Reinforced Polymers) mesh inserted inside an inorganic matrix and a reinforced repointing of mortar joints using high strength stainless steel cords. The tests were done on panels assembled in the laboratory and were carried out using a widely-known test method (diagonal compression test). Masonry materials include stone and brick in which a variety of unit sizes and forms are produced. Mortar was a hydraulic lime/sand with a plasticiser added to improve workability. The failure loads, in-plane and out-of-plane deflections and failure modes were recorded. Based on the results of the experimental program, it appears that the in-plane shear strength of the reinforced masonry wall systems increased significantly compared with that of control unreinforced masonry panels.
