    Bridge Inspection Program Continues to Evolve Through the ’s and Into the Next Millennium • Bridge Inspectors Training Manual 90 (FHWA; Updated in ) • State of the art inspection techniques • Expanded coverage on culverts, fracture critical, cable-stayed bridges, prestressed segmental bridges, and underwater inspectionsFile Size: 5MB.   This paper studies the feasibility of using UASs for fatigue crack detection in bridges with fracture critical members (FCMs) through real-time and postflight visual inspection. The effects of surface illumination on the maximum crack-to-camera (MCC) distance at which a fatigue crack can be detected were investigated in the laboratory.

    Fracture critical: A fracture-critical bridge typically has a steel superstructure with load (tension) carrying members arranged in a manner in which if one fails, the bridge could partially or totally collapse. Examples of fracture critical bridges are two girder bridges or most truss bridges. (State of Indiana Libraries) Services. Navigate; Linked Data; Dashboard; Tools / Extras; Stats; Share. Social.

The first day of the training focuses on the concept of fracture critical members (FCMs), FCM identification, failure mechanics, fatigue in metal, and an overview of NDE methods.

Day two includes demonstration sessions and hands-on applications of NDE techniques for dye penetrant, magnetic particle testing, Eddy current testing, and ultrasonic.
