The reinforcement splices are inevitable in modern reinforced concrete (RC) constructions, and various types of reinforcement splicing methods are currently available in practice. In this study, to overcome some disadvantages in a traditional lap splicing method, the grouted-mechanical splices with thread-deformed reinforcing bars were adopted in RC column-foundation connections. Typical cyclic loading tests were conducted on RC column-foundation specimens, and test results were compared with numerical analysis results. The finding obtained from this study indicated that the grouted mechanical splicing method utilizing the thread-deformed reinforcing bars can provide improved constructability and good seismic performances.
