  In this study, the simulation of the thermal behavior of an arch dam which is subjected to the environmental thermal action during service, the method of solution adopted as well as the evaluation of the different parameters will be described in detail. The case study is a double curvature concrete arch dam (Karun-1 dam) with 200 m height in the Southwest of Iran which is modeled by the powerful scientific ABAQUS software. The ABAQUS program has the ability to transfer heat within the body of the dam with high accuracy, the main challenge of previous researches in the field of thermal analysis of arch dams. In addition to thermal loads, in this study, the effects of hydrostatic pressure and weight of the dam and reservoir-dam-foundation interaction also have been considered and it became distinct that the thermal effects on dam displacements, stresses and strains are significant and would not be neglected.

  In this study, effect of vertical contraction joints on the Karun-1 arch concrete dam safety certainly under effect of thermal loads was looked over by means of the relatively 3D finite elements exact simulation of the geometric, material behavior and boundary conditions of the dam using ABAQUS package. This software has good potentials for modeling three dimensional heat transfer thorough dam volume. Arch, cantilever and principal stress tensors as well as displacement vectors were selected as stability indexes safety control and deeply examined. It was revealed that the contraction joints have significant effects in the thermo-static response of the dam and if any of two important factors e.g., contraction joints or thermal effects are not considered in Kurun-1 dam processing, the significant errors in computing displacements and stresses and consequently in dam stability qualification can be occurred.
