Compares the structural response of unretrofitted unreinforced masonry (URM) walls with URM walls retrofitted on one side with glass-fiber-reinforced polymer (FRP) laminates. Six walls were tested using the diagonal tension standard test procedures. In this investigation, 2 objectives are considered. 1) a comparison is made between the improvements in performance provided by retrofitting a single-wythe wall vs. that provided by retrofitting a triple-wythe wall. 2) the performance enhancement provided by the FRP is compared with 2 mortar-to-brick strength ratios.
