Prioritization Strategy for Replacing Deteriorating Partial-Depth Precast Concrete Deck Panels in Florida
Publication: Journal of Bridge Engineering
Volume 21, Issue 6
Abstract
Precast deck panel bridges have a history of poor performance in Florida. In the aftermath of five localized punching shear failures, a decision was made to replace all 127 deck panel bridges in southwest Florida over a 10-year period. This paper describes the strategy used for prioritizing their replacement. Two risk indices focusing on safety and importance were developed for this purpose. The safety index was determined from available inspection records and the importance index from annual daily traffic. Forty-two bridges had already been earmarked for replacement. The 85 remaining bridges were ranked using this protocol; 39 were rated as being in good condition. The replacement order for the remaining 46 bridges was prioritized. The validity of the approach was confirmed by the subsequent localized failure of two bridges, both identified as being at high risk.
