Christine Wittich, assistant professor in Civil and Environmental Engineering, holds a damaged anchor bolt from a grain bin that was part of the destruction caused by a derecho that struck Iowa in August 2020. Wittich received a rapid response grant from NSF to research the damage from the derecho. Specifically, she is studying damage to ag structures such as silos aiming to determine how construction standards and practices might help such buildings withstand future storms. On screen behind her, is a 3-D rendering of damage to a Luther, Iowa, farm. The detailed scene was produced by Ricky Wood, associate professor in civil and environmental engineering, using his drone technology. February 5, 2021.
