In this study, reversed cyclic loading tests were conducted to evaluate the performance of reinforced concrete columns with short lap splice length at the plastic hinge zones. The test parameters include the length and the details (typical and full moment capacity splice) of lap splices and the ratio of shear span to section height (a/h = 3.0 and 6.0). Test results showed that the strength and ductility of columns were significantly varied depending on the lap splice details and lap splice length. Typical lap slice could not attain target flexural strength but deformation capacity; on the other hand, full moment capacity splice could not achieve sufficient deformation but target flexural strength. In addition, the aspect ratio also had significant impact on the performance of lap splices due to change of the bond demand in the splice zone.
