In order to analyze the distribution of temperature within concrete structures, it is understood that the characteristics of hydration heat and the boundary condition affect the accuracy of the analytical results. Especially, if the analysis is launched from the distribution of temperature around the concrete surface. Special attention is necessary to focus on the assumption of boundary condition due to the fact that the accuracy of analytical results is critically affected by the boundary conditions. Generally, the coefficient of heat conduction of the framework is utilized in the assumption of boundary conditions to carry out the analysis. However, because of the coefficient of heat conduction of framework varies with the properties of framework, surface condition and the environmental temperature, it is very difficult to measure and predict the distribution of temperature on the framework precisely. As a result, the author attempted to propose a new method to calculate the distribution of temperature of concrete by using infrared image analysis. Compared to the previous researches, this method offered more comprehensive consideration on the boundary condition from the surface of concrete to environmental atmosphere. In addition, it was also concluded that a three dimension FEM program for analyzing temperature distribution suggested by the authors was effective.
