TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 354: Inspection and Management of Bridges with Fracture-Critical Details explores the inspection and maintenance of bridges with fracture-critical members (FCMs), as defined in the American Association of State Highway and Transportation Officials' Load and Resistance Factor Design (LRFD) Bridge Design Specifications. The report identifies gaps in literature related to the subject; determines practices and problems with how bridge owners define, identify, document, inspect, and manage bridges with fracture-critical details; and identifies specific research needs. Among the areas examined in the report are inspection frequencies and procedures; methods for calculating remaining fatigue life; qualification, availability, and training of inspectors; cost of inspection programs; instances where inspection programs prevented failures; retrofit techniques; fabrication methods and inspections; and experience with fracture-critical members fractures and problems details.

This manual is a synthesis of published literature as well as the collective experience gathered from participants of a workshop held at Lehigh University August 14-15, 2002 [herein referred to as the Fatigue Workshop]. It presents what are the consensus best practices for repair and retrofit of fatigue cracks in steel bridges as of 2010. The manual is also a guide for owners and consulting engineers to use for design and detailing of repairs and retrofits for fatigue cracks. It should be used in conjunction with existing specifications, codes, and engineering judgment. In addition to designing and executing the repairs and/or retrofits, there are numerous other steps involved in the inspection and assessment of a cracked bridge member. Detailed discussion of inspection and fatigue and fracture assessment are beyond the scope of this manual and, therefore, are only briefly discussed below with reference to other documents.
