Session Title
Declassifying Fracture Critical members Using System Redundancy
Track Title
Bridges
Event Description/Abstract
As a consequence of past bridge failures and the aging of existing infrastructure, the FHWA has identified new criteria within a recently released memo to classify fracture critical bridges using the concept of system redundancy. Ciorba has investigated 20 bridges in Illinois with fracture critical members (FCMs). This presentation details the analysis criteria required by the FHWA memo, the various categories of FCMs in the 20 bridges, our finite element analysis, and ultimately our results.
