Evaluation of the cause of cracking in bridge #MEG-124-6.78

Title from cover.; "October, 1999."; Executive summary laid in.; Includes bibliographical references (p. 63).; Final report.; Sponsored by the Ohio Department of Transportation in cooperation with the U.S. Department of Transportation, Federal Highway Administration; Harvested from the web on 3/6/06Bridge MEG 124-6.78 was a single span, composite, adjacent, prestressed box girder bridge with a 45E right forward skew. After being in service about 1 year, the three edge beams on one side of the bridge showed extensive bottom flange cracking. Diagonal and vertical cracks were visible on the sides of the fascia beam. Field tests done on the bridge in a previous study indicated that the cracking did not occur due to overload or improper load distribution. Destructive testing was performed and a it was found that the caue of failure was construction error. The bridge was rebuilt and tested--this testing confirmed that, properly constructed, the bridge was adequate.Bridge MEG 124-6.78 was a single span, composite, adjacent, prestressed box girder bridge with a 45E right forward skew.
