There is both field and laboratory evidence that demonstrates the detrimental impact an unreinforced masonry infill imparts on a structure due to its interaction with the bounding frame. There is a current lack of reliable and effective retrofit techniques for this group of structures. A new retrofit technique specifically for unreinforced masonry infills in non-ductile reinforced concrete frames is under investigation and presented here. The technique uses a ductile fiber-reinforced mortar material referred to as Engineered Cementitious Composites, or ECC. A series of experiments have been performed in order to examine the impact of a thin layer of ECC applied on masonry alone as well as when it is applied on a masonry wall bounded by a non-ductile reinforced concrete frame. Results indicate that the ECC can help keep unreinforced masonry walls intact to large lateral drifts, adding significant ductility to the structural system under cyclic loading.
