Three Dimensional Thermal Stress Analysis of Concrete Arch

The purpose of this paper is to develop a model to investigate temperatures and thermal stresses of concrete arch dam in operating phase. Then probable cracked areas and area with high concentration of tensile stress can be predicted. A three-dimensional finite element model was used for this purpose.
