Abstract
A new approach in 3D numerical modeling for unsteady phased thermal-stress analysis of a massive concrete hydraulic structure is presented. The temperature field is computed first, providing a drive for the unsteady, nonlinear, viscoelastic, stress-strain analysis. This model is devised with actual initial and boundary conditions, appropriate material properties, and the observed concrete placement schedule. The verification is based on the field investigations of the Platanovryssi dam. The results of a long-term analysis have shown close agreement with the observed dam conditions. The proposed model presents a reliable tool for thermal-stress computation and transverse contraction joint distance evaluation. © 2013 Copyright Taylor and Francis Group, LLC.
