DESCRIPTION:
The course curriculum reflects current practices and addresses new and emerging technologies available to bridge inspectors. In addition, the course includes exemplary training and hands-on workshops for popular types of nondestructive testing (NDT) equipment and a case study for the preparation of an inspection plan for a fracture critical bridge. The first day of the course focuses on the concept of fracture critical members (FCMs), FCM identification, failure mechanics, and fatigue in metal. These fundamentals are followed by an overview of NDT methods. Day two provides demonstration sessions and hands-on applications of NDT techniques for dye penetrant, magnetic particle testing, Eddy current, and ultrasonic testing. Days three and four emphasize inspection procedures and reporting for common FCMs, including problematic details, I-girders, floor beams, trusses, box girders, pin and hanger assemblies, arch ties, eyebars, and cross girders/pier caps. A case study of the preparation of an inspection plan of a fracture critical bridge closes out the presentation. The course includes daily participant assignments. The schedule can be tailored to specific agency requirements. OUTCOMES:
Upon completion of the course, participants will be able to:- Identify fracture critical bridges, fracture critical bridge members, and fatigue prone details
- Categorize contributing factors in the initiation and propagation of fatigue cracks
- Perform an intensive, in-depth, and thorough fracture critical member inspection
- Identify various crack types and access their impact on the performance of the member
- Evaluate, select, and facilitate the use of available NDT methods
- Recommend a necessary course of action based on inspection findings
TARGET AUDIENCE:
Those benefiting most from this training will be public and private-sector bridge inspectors, supervisors, project engineers, maintenance engineers, shop inspectors, shop foreman, and others responsible for shop fabrication and field inspection of fracture critical steel bridge members. Participants should have completed NHI course FHWA-NHI-130054 Engineering Concepts for Bridge Inspectors and/or FHWA-NHI-130055 Safety Inspection of In-Service Bridges, or possess equivalent field experience relative to bridges to fully understand bridge mechanics and bridge safety inspection procedures as required by the National Bridge Inspection Standards. |
