Guidance for Identifying Nonredundant Steel Tension Members (NSTMs)

This research directly addresses the challenges the Georgia Department of Transportation (GDOT) has faced regarding design engineers inaccurately over-specifying nonredundant steel tension members (NSTMs) on new steel bridge designs. The subsequent additional inspection requirements have resulted in increased costs, fabrication disputes, and project delays. As such, guidance is critical for practicing engineers to identify such members accurately. Further, the proposed analysis of an IRM or SRM offers GDOT significant financial, resource, and safety benefits.
