•Three-dimensional finite element model of a high arch dam was prepared.•Finite element model was calibrated in thermal and static conditions.•Micro geodesies measurements and instrumentations were used for calibration.•Static safety of Karun III Dam was evaluated using updated material properties.
In the present paper, a comprehensive finite element model of Karun III double curvature arch dam is calibrated based on the micro geodesies measurements and instrumentation. Thermal properties of concrete are obtained by transient thermal analysis and the results are compared with those obtained from thermometers. Thermal analysis features include air temperature, water layers temperatures, and the solar radiation on the exposed faces. Structural calibration features include thermal distribution within the dam body, dam self-weight, hydrostatic pressure, and silt load applied on the model of dam–reservoir–foundation system. Finite element model calibration provides updated information related to the current dam status and can be used for further safety evaluations.
