How is the thermal expansion of concrete considered in the design and analysis of a concrete dam?
Thermal expansion in concrete dams is minimized by using materials that can endure temperature changes and installing expansion joints. Engineers calculate the potential thermal expansion and contraction based on the coefficient of thermal expansion of the concrete. Designs use expansion joints to allow for greater mobility while reducing stress, preventing cracking, and maintaining structural integrity.
Other strategies to reduce thermal effects include managing the temperature throughout the curing process and selecting the appropriate concrete mix, which occasionally includes additives to reduce heat generation. This maintains the dam's irrigation efficacy by ensuring the dam's stability and performance across a wide temperature range.
