    Abstract

    Most bridges located in major cities experience large traffic volumes, which require bridge decks to be extremely durable under this constant loading. Concrete filled steel grid bridge decks have exhibited extended service lives under severe urban traffic conditions, and in some instances, have been in use for more than 60 years. Concrete filled steel grid decking can be a viable option for both decking and re-decking operations since it can be installed quickly, and because it can be equipped with stay-in-place form pans. The current PennDOT BD-604 design standard appears to be conservative in its specification of allowable span lengths. The present research will investigate the use of concrete filled steel grid deck on greater span lengths. The BD-604 is based on the performance of older grid deck installations, and does not take advantage of modern materials, or more advanced analysis and design techniques. An experimental evaluation of the fatigue and ultimate strength performance of a series of full-depth, overfilled, two span continuous grid deck panels on a simulated 10' stringer spacing is carried out. The testing was conducted at the University of Pittsburgh Main Campus in the Watkins-Haggart Structural Testing Laboratory in Benedum Hall. Based on the results from this testing it appears that the span lengths in the BD-604 may be increased by a factor of 1.67.
