Abstract:The overall objective of this research phase is to develop a possible stochastic methodology for quantifying the probability of bridge failure against heavy truck collisions which can result in fires and that can impact the safety of bridges. In 2021, the National Bridge Inventory (NBI) had over 618,456 bridges and culverts registered in its U.S. bridge database, of which 13,963 bridges and culverts are in Virginia. Data shows that 93,000 bridges in the United States and 2,689 bridges in Virginia have one or more traffic lanes under the structure. Data for the Virginia bridges were collected and analyzed within a methodology for classifying bridges most vulnerable to heavy truck collisions and resulting structural failures from subsequent fires. Given the on-site availability of the three specified data types, 17 bridges were selected from the commonwealth of Virginia to form a test-bed study site. Finally, stochastic models were formulated for estimating the probability of bridge failure from subsequent fires. Research findings may interest those connected to bridge programs at the Federal, State, and local agencies.
