A fracture critical bridge is a bridge or similar span that is vulnerable to collapse of one or more spans as a result of the failure in tension of a single element. While a fracture critical design is not considered unsafe, it is subject to special inspection requirements that focus on the tension elements of its structure.
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
The NBI can classify bridges as "structurally deficient," which means that the condition of the bridge includes a significant defect, which often means that speed or weight limits must be put on the bridge to ensure safety; a rating of 4 or lower on any of items 58, 59, 60, or 62 (deck, superstructure, substructure, and culverts, respectively ...
Bridges such as the one in Baltimore are classified as "fracture critical" by the federal government - meaning that if one portion of the bridge collapses, it's likely to take down the rest of the ...

The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
A structure without redundancy is called fracture-critical, meaning that a single broken component can cause the collapse of the entire structure. Bridges that failed due to lack of redundancy include the Silver Bridge and the Interstate 5 bridge over the Skagit River. Parallel and combined systems demonstrate different level of redundancy.
