Extreme Values of Climatic Thermal Stresses in Concrete Box Cross-section
(2011) XXI Nordic Concrete Research Symposia, 2011 43(1). p.187-190- Abstract
- The thermal stresses in a concrete bridge are affected by the surrounding climate. Varying temperature will produce movements which, if restrained, may induce stresses in the structure. To predict the thermal stresses in box cross-sections, FE simulations have been performed with extensive climatic input data to simulate the temperature and resulting stress fields in the hollow concrete arch of the New Svinesund Bridge. The results show that the thermal tension stresses can be above the tension strength of the concrete. A linear approach for estimating the thermal stresses may give an overestimation, due to non-linear effects.
