Recently a hollowed precast concrete (HPC) column system has been developed for construction of building in order to improve constructability and economy during the construction. The HPC column supports beams during construction so that local compression acts on the column. At that time, the stress distribution from the beams to the column varies if hollow size varies. After the hollow is filled with grout concrete, the column has two layers, outer and inner elements with different compressive strength each other. Therefore, hollow size affects axial capacity of column after filling the hollow. Based on the above background, this paper performed a finite element (FE) analysis with parameter of hollow size to find the stress distribution of hollowed PC column during construction as well as after construction. As an analysis result, the wider the hollow size is, the less local compress strength is during construction. Also, the axial compressive resistance of column decreased when the hollow size is wider.
