Seismic resistance of several buildings in Turkey is deficient. Strengthening of these buildings with commonly used reinforced concrete (RC) infills requires excessive construction work. The main objective of this study is to develop a feasible, effective, and yet economical strengthening technique that does not disturb the inhabitants. The proposed method is based on application of steel fiber reinforced higher strength mortar on the plaster of masonry walls. An optimum steel fiber reinforced mortar (SFRM) was obtained in preliminary material tests. RC frames strengthened by applying the mortar onto brick masonry plastered infill walls were tested under reversed cyclic lateral loads simulating earthquake. The frames were 1/3 scale, 1 bay, and 2 story. Totally 10 frame tests were performed. Tests included 4 different reference tests, and 6 strengthened frame tests having various mortar thicknesses and steel fiber volumetric percentages. Frame having 2 percent SFRM anchored to the frame with 20 mm thickness carried approximately 2 times the lateral load of the plastered brick masonry reference frame.
