In this research, moment calculation for reinforced concrete column using ultra high-strength concrete under constant axial load with assumption of liner strain distribution, which was so-called "fiber model", was conducted. This calculation took account of volume change of concrete regarding autogenous shrinkage and creep. Using the proposed fiber model, bending behavior of reinforced concrete (RC) column with ultra-high strength concrete is simulated. As a result, autogenous shrinkage make
