| A methodology for computing thermal loads in arch dams is proposed. The methodology considers the non-uniform distribution of solar insolation over dam faces due to shading, curvature of dam faces, orientation and slopes. Since in most cases mean daily global solar radiation is that only available, a methodology for estimating hourly solar energy reaching dam faces is described. The methodology is applied to a case study where observations from 21 thermometers embedded in the concrete and where data of climatic variables are available. The concrete temperature field is successfully computed, with good agreement between observations and predictions. The proposed methodology is compared with other approaches and the consequences on the stress calculations are analyzed. | |
