All Theses
This thesis investigates the strength of prestressed concrete channel girders used
in bridges in South Carolina and how to improve their load distribution. The specimens
are 30 feet in length, 33 inches wide and 17 inches deep. South Carolina has 377 bridges
containing prestressed concrete channel girders and many of these bridges received a
poor load rating in a recent load rating project conducted by the South Carolina
Department of Transportation (SCDOT). The research included flexural testing of seven
individual channel girders and load distribution tests of three transversely post-tensioned
channel girders. Individual flexural testing was done to determine the …
