Intelligent Infrastructure Systems developed an automated load rating tool for the Burlington-Bristol Bridge (BBB) lift and tower spans. The Burlington-Bristol Bridge connects Bristol, PA and Burlington City, NJ and is 3,144 feet in total length with a 540-foot main-span through truss that lifts 75 feet vertically to accommodate large ships. The tool is being developed in a manner to allow for simple future rating efforts where new vehicle types or analyses are required. Tasks included review of prior dead load calculations, review and construction of a Finite Element (FE) model for rating purposes, and computation of member capacities. The automation will enable efficient re-rating for any future or potential changes in the structure’s weight, load distribution, load carrying capacity, or additional analysis vehicles.
