Non-linear temperature distribution induced by the hydration heat generates thermal stress in mass concrete. At early ages, such thermal stress may cause thermal cracks in the structure, since the strength of concrete is low. And it is very important to predict the effect of hydration heat on the structure because thermal cracks may give an effect on the durability and safety of the structure.
Up to now, a lot of works have continued to predict temprature distribution and thermal stress in the structure. In most of such works, however, the inside of structure was considered as adiabatic state to predict temperature distribution and the thermal stress. And due to the lacks of appropriate analysis models after crack occurred, it was difficult to describe the real behavior of structure.
This paper deals with the prediction of the temperature distribution in the structure using the rate of hydration heat genaration and also estimation of the behavior of structure before and after crack occurred due to hydration heat using "The Crack Band Model" which was proposed by Bazant.
