Live-Load Testing and Finite-Element Modeling of a Fracture Critical Bridge

The objective of this research is to determine the in-situ load rating of a fracture critical bridge over the Snake River in Idaho. This will be accomplished by performing a live load test and monitoring the response of the bridge. The data from live-load test will be used to quantify behavior and the influence of wider spacing (applicability of American Association of State Highway and Trasportation Officials (AASHTO) specifications), cross beams (not typical in an I-girder bridge) and cross bracing. A three-dimensional (3D) finite-element model of the bridge will then be created and validated with the live-load data. This model will then be used to obtain the load rating of the bridge and used to identify important parameters that influence the behavior of fracture critical bridges.
