As the ridges become larger and larger, a structural type that enables effective utilization of the long span and space is required. In the construction stage, the steel column supports the installation load. However, in order to secure the stability against the out - of - plane deformation of the steel column due to the lateral pressure when the concrete is laid, a binding frame is installed inside the steel pipe at constant intervals to resist the concrete installation pressure. When the concrete is cured and its performance as a composite section is exerted, a stress is generated which pushes the steel pipe out of the plane by the column compressive force. In this case, since the binding frame controls the deformation, the local buckling is delayed and the constraining effect on the concrete is increased. In order to evaluate the structural performance and behavior of the composite mega column according to the eccentricity effect and the effect of the binding frame, we carried out a structural test by fabricating eight monopole specimens with the binding frame reinforcement, reinforcing gap, reinforced cross section and eccentricity , And the experimental results are compared with the KBC2016 design formula.
