Description: This report concerns the initial efforts of a research study investigating the remaining capacity and life of cast-in-place reinforced concrete deck-girder (RCDG) bridges with diagonal tension cracks. A database of 442 bridges constructed from 1947 to 1962 was developed to identify salient parameters related to bridges with diagonal tension cracks in the Oregon Department of Transportation bridge inventory. The database was queried to provide summary details for individual parameters and relationships between parameters. In additional, a bridge analysis was conducted on an in-service RCDG bridge with diagonal tension cracks. A linear finite element model of the bridge provided reasonable prediction of cracking.
