The columns of older reinforced concrete (RC) buildings generally have limited reinforcement details. Thus, they could be vulnerable to earthquake ground motions, leading to partial or complete building collapse. In this study, high-performance fiber-reinforced cementitious composite (HPFRCC) was applied to RC columns to improve their seismic behavior. Experimental tests were conducted with two full-sized specimens with limited reinforcement details, including short lap splices, while unidirectional loadings were applied to the specimens. The seismic behavior of RC columns was substantially improved by using HPFRCC.
