Shear Capacity of Prestressed Girders |
摘要: |
The main objectives of this research are to: (1) determine through experimental testing the shear capacity of typical prestressed concrete bridge girders that have been subjected to a corrosive environment; and (2) evaluate retrofit measures to increase the shear capacity. As part of the research, six girders will be salvaged from a decommissioned bridge on I-215. The bridge was originally comprised of four spans with a significant slope running longitudinally along the length of the bridge. The specific girders that will be tested for this project will be taken from the span that at the low point of the bridge and hence has had a significant amount of water exposure over the years. The reduction in the shear capacity of these girders is unknown and has been difficult to quantify. Because UDOT has other bridges in service that have been subjected to similar environmental conditions, a quantification of the shear capacity and methods of retrofit will aid in making maintenance decisions. |
