Caltrans to retrofit double-deck bridges

Article Abstract:

University of California, San Diego researchers and California Dept of Transportation personnel have devised a method of reinforcing elevated highway to make them more earthquake-resistant. This method will be used to repair the damaged Central and Southern Viaducts in San Francisco in 1993. The design entails the addition of concrete edge beams connected to the deck and columns by prestressed concrete cap beams and the replacement of square columns by circular columns. The system will minimize repair costs in case an earthquake occurs.
