Session Title
Twin Tub Girder Retrofits for System Redundancy
Track Title
Bridges
Event Description/Abstract
Due to the perceived risk of fracture critical members (FCM) in steel bridges, hands-on inspection are man- dated. This presentation describes the redundancy evaluation of three twin tub girder bridges with FCM designations. The analysis follows the AASHTO Guide Specifications for Analysis and Identification of Fracture Critical Members and System Redundant Members. Based on the outcomes of these analyses, the feasibility of retrofit alternatives will be assessed for the purpose of reclassifying FCMs as system redundant members.
