Composites help to repair earthquake-damaged bridges
It can take weeks to repair bridges damaged in devastating earthquakes like the ones in Ecuador and Japan. But an interesting new process developed by a team of University of Utah researchers reportedly can fix bridge columns in a few days. It can also be used to retrofit bridges to make them more earthquake-safe.
This initiative, led by University of Utah civil and environmental engineering professor Chris Pantelides, involves creating donut-shaped concrete “repairs” that are lined with a carbon fiber-reinforced polymer. The material is stronger than concrete and steel and is built around the bottom and top of each bridge column.
