Testing of Multi-Span Bridges with Full-Span Precast Prestressed Concrete Panels (Phase 1)
The purpose of this study was to asssess the behavior and durability of multi-span bridges constructed with full-span prestressed concrete form panels prestressed concrete from panels for bridges with spans of 40 ft. or less is an economical method of construction due to the reduction of on-site formwork and labor required by alternate case-in-place systems. In this research, a pair of two-span bridges utilizing full-span prestressed concrete from panels were fabricated and tested in the Karl H. Kettelhut Structural Engineering Laboratory at Purdue University. Time-dependent effects were monitored during the cast-in-place (CIP) concrete cure period of each bridge. At the conclusion of this period, each bridge was subjected to 5 million cycles of repeated service loading prior to a final loading to failure. In addition, one of the test and five smaller composite specimens were exposed to a 15% sodium chloride solution followed by 3 days of drying at minimum of 100 deg F. The durability of these bridges were then assessed by determining the potential for the build-up of chlorides at the boundary of the prestressed panels and CIP topping, and the resistance of the reinforcement to corrosion induced by chlorides.
