In this study, cyclic loading tests of cantilever rectangular reinforced concrete columns were performed to evaluate the seismic performance of relatively short lap splices with non-seismic hoop details. The lap splice length of 30 times diameter of longitudinal reinforcement (30) with the hoop spacing of a half of effective column depth(0.5) showed adequate flexural strength and ductility even though smaller lap splice length than ACI318 was used in plastic hinge zone.
