ABSTRACT
An experimental investigation was conducted to study the behaviour of unreinforced masonry (URM) walls retrofitted with composite laminates. Five masonry-infilled steel frames were tested with and without retrofit. The composite laminates increased the stiffness and strength and enhanced the post peak behaviour by stabilizing the masonry walls and preventing their out-ofplane spalling. Tests reported in this paper demonstrate the efficiency of FRP laminates in improving the capacity of URM containing the hazardous URM damage, preventing catastrophic failure and maintaining the wall integrity even after significant structural damage.
