TRB's National Cooperative Highway Research Program (NCHRP) Research Report 883: Fracture-Critical System Analysis for Steel Bridges presents a proposed specification for the analysis and identification of fracture-critical members and system-redundant members. The report describes the analysis methodology and provides application examples. The analysis methodology is based on comprehensive 3-D finite element analyses (FEA) and case studies to evaluate the redundancy of new and existing steel bridges with members traditionally designated as fracture-critical members (FCMs), including simple- and continuous-span I-girder and tub-girder, through-girder, truss, and tied-arch steel bridges.
