Fiber/Epoxy Composites Strengthen Bridge Columnsby Ski Brown, California Dep of Transportation, Sacramento, United States,
Abstract: The California Department of Transportation is using high strength fiber/epoxy composites to strengthen existing reinforced concrete bridge columns. These advanced composite materials are used to give existing columns the necessary flexural ductility and shear capacity to resist earthquake loads. The strengthening of these columns is a part of an overall effort by this State to retrofit existing bridges so that they are capable of withstanding the current design earthquake loads.
