This paper presents a technique for retrofitting nonseismically reinforced concrete (RC) masonry-infilled frames with textile-reinforced mortar (TRM) jacketing. In the present study the application of TRM is examined on nearly full-scale, as-built and retrofitted, three-story frames, subjected to in-plane cyclic loading. The results of testing a 2:3 scale, as-built frame representing typical structures with nonseismic design and detailing characteristics and of a companion frame retrofitted via TRM jacketing are presented and compared in terms of the efficiency of the proposed technique to enhance the strength and deformation characteristics of substandard infilled frames.
