Thermal expansion coefficient is very important value to analyze the thermal deformation behavior of structural element made by high-strength concrete in early age. As autogenous shrinkage increases in high-strength concrete, the evaluation of autogenous shrinkage in the condition that receives high temperature is important. Therefore this study considered the calculation method of the thermal expansion coefficient by taking this deformation into consideration. In this study, the experiments on thermal deformation behavior using full scale column and small specimens were carried out. As the result, we obtained the result that thermal expansion coefficient changes with time. And we showed that the thermal coefficient could be evaluated by using the equation considered of change in the relative humidity inside concrete.
