Donut Repair 1 (IMAGE) University of Utah Caption University of Utah civil and environmental professor Chris Pantelides stands next to a donut-sized "repair" he and a team of researchers designed that can fix a damaged column on a bridge. The repair -- a black concrete donut surrounding the ends of the column and wrapped with a composite fiber material -- can be deployed on bridges damaged in an earthquake much more quickly than through the standard procedure.
