The use of concrete in construction is very common even though there are several problems such as massive structure self-weight and it causes the increment of the seismic load carried by structure. Therefore, engineers usually prefer the use of hollow cross-sections in reinforced concrete since it gives higher structural efficiency. This research was done to analyze Hollow Concrete Column (HCC) using the finite element method with the help of MIDAS FEA application to obtain an efficient and effective model ratio between the hollow-core variation which use CFRP (Carbon Fiber Reinforced Polymer) as wrapping. The analysis result shows that for the solid cross-section sample, the use of CFRP correlates to the needs of force resistance because the effectivity curve shows that the line intersects with one another at some variety of eccentricity. It also shows even though the effectivity increases with the increment of the hollow ratio, there is a capacity reduction of ∓ 5.5% for each 5% increment. From the analysis, it shows that the effectivity of the sample with CFRP wrapping exceeds the solid conventional sample, where the best ratio is 30%.
