This study aims to estimate the residual strength by experimental and analytic method and analyze the elements affecting fire resistant performance of reinfored concrete column. For predicting strength reduction rate and fire resistant rate of reinforced concrete column $500^{\circ}C$ isotherm method of EN 1992-1-2, a simplified calculation method, was used. The residual strength rate of reinforced concrete column, which is exposed to standard fire for 180 minute and assumed to bear the pure axial compressive force, was calculated with inner temperature data achieved from fire resistance test results. Further, the analysis of relations of fire resistance rate affecting elements for reinforced concrete member were performed. The residual strength rate of reinforced concrete column estimated in this study may be used as a significant information for establishing fire load factor and load ratio on performance based fire resistant design.
