VERIFICATION OF COMPOSITE BEHAVIOR OF A PRECAST DECKED SIMPLE SPAN

This paper documents the reconstruction of a simple span bridge redecked with full-depth, full-width precast concrete panels connected to act in a composite way with supporting stringers. It also reports the results of full-scale load tests and of an analysis conducted to evaluate the composite behavior of the precast decked span. Eight precast concrete panels, each 6 ft 3 in. x 45 ft x 8 in. thick, were used to form the deck. The panels were cast with holes and positioned on top of supporting stringers with bearing pads measuring 2 in. x 6 in. x 1 in. thick. Steel stud connectors were welded to the top flanges through the holes. Keyways between adjacent panels and deck-stringer gaps were sealed to retain epoxy mortar that was poured through the deck openings. The panels were placed in an operation lasting about 5 hours. Welding the studs, sealing the connections, and pouring the epoxy mortar took about 20 hours. Full-scale load tests were conducted on the redecked span by placing a 13-ton vehicle at different locations while live-load deflections were recorded. A full-composite, finite element model of the bridge was used to correlate the measured deflections. The comparison of measured and full-composite deflections of the model indicates that the span behaves in a full-composite manner.
