The utilization of composite columns is increasing due to the construction of high-rise buildings and large buildings. The commercially available concrete chimney steel column (ACT I) is a stable and economical structure, but there is a limit in the section size to be applied to a composite column subjected to a high load. We have developed a composite mega column with an integral structure by adding a plate to the central part of the ACT I column and installing a binding frame at a certain interval inside the central plate. In this study, to evaluate the compressive performance of the composite mega column, four test specimens were constructed with binding frame reinforcement, reinforcement spacing, and reinforced cross - sectional area. The structural performance of the composite section is compared with that of KBC2016 to evaluate the behavior of the specimen.
