A reinforced concrete column restrained by a steel plate and reinforced concrete column using high strength concrete (real strength 100N/mm^2) have been studied experimentally to determine heat and moisture migration in a reinforced concrete column during a fire. This report describes the fire endurance, and shows a measurement result considering temperature distribution, hydrate distribution and vapor pressure inside the reinforced concrete column. The following conclusions were obtained. (1)The reinforced concrete column restrained by a steel plate prevented the explosion of concrete and the inner concrete and reinforced steel bar temperature rise was restrained. In the fully cured high strength reinforced concrete column of 100N/mm^2 class, an explosion was eased. (2)The temperature distribution, hydrate distribution and vapor pressure inside the reinforced concrete column subjected to fire heating was determined for the most part.
