TPF- 5(238) Design and Fabrication Standards to Eliminate Fracture Critical Concerns in Two Girder Bridge Systems
This is pooled fund study involving FHWA, AISI, Army Corps of Engineers, FHWA, IN, IA, ID, MN, NC, OR, VA, WI. Two girder bridge systems, as well as other non-redundant systems, were developed in the two decade period starting in the 1950's. Unfortunately, knowledge of the fatigue and fracture limit states was not sufficiently advanced to avoid problems in service. Since the 1970s, there have been tremendous advances in materials, fatigue analysis, fracture mechanics, fabrication techniques, and inspection. This project will revisit the concept of Fracture Critical Bridges in the light of the advances that have been made over the last 35 years. In addition, the project will establish guidance that provides a high level of bridge safety that can then form the basis for in-service inspection decisions. The results of the research will be transformative with respect to the steel bridge industry if fully implemented. Dr. William Wright of Virginia Tech is Co-PI on the project.
