Creep test of Fc100N/mm2 concrete and strain measurement of reinforced columns in an actual building was performed and creep strain with structures building was considered. As a result, creep factor obtained from creep test by a test piece was revised according to sectional form, and when adding elasticity strain and creep strain which form every structures flame building on each floor, it was confirmed that it’s possible to predict axial strain to construction load.
