Abstract
In this study, two 3DCP‐RC(three‐dimensional concrete printing‐reinforced concrete) composite columns were fabricated surrounded by the outer shells containing short fibers with 1% or 2% volume per 3D printed mortar and compared to the seismic performance with a conventional RC column through quasi‐static cyclic loading tests. As a result, it was confirmed that the maximum horizontal strength and the ductility during the ultimate state on both 3DCP‐RC columns were enhanced in comparison with that of conventional RC. The maximum principal strain distribution measured by digital image correlation method revealed that crack distribution was slightly different among the 3DCP‐RC columns and the conventional one. And the short fiber volume contained in the outer shell mortar had an only slight impact on seismic performance and it can be attributed to its printing path.
