Fracture Critical Determination: Case Studies and Strategies - Part 3 [B18]

Part 3 of this series will present three case studies in design and repair. First, the case study investigation and repair the 7 span fracture critical Diefenbaker Bridge, which experienced brittle fracture, will be presented. Next, a presentation of the design and construction of a load path redundant truss, which eliminated all fracture critical members and the necessity of fracture critical member inspection, will be given. And lastly, this session will include an overview of the superstructure of the cable stayed spans of the Goethals Bridge that provided a unique level of redundancy and improved overall structural resiliency.
