The design of prestressed composite steel bridges
… new structural systems: prestressed concrete and composite design. Each of these new construction methods has advantages and limitations. A new idea of combining these two structural systems into one could result in more economical structures particularly suited for long span bridges. The …

FEA methodology for system-level redundancy evaluation: Application to non-composite steel bridges
<p>Currently, all steel bridges with members designated as Fracture Critical Members (FCMs) are required to undergo hands-on inspections every 24 months. A FCM is a primary steel tension member (or portion of) which failure results in collapse or loss of serviceability of a bridge. However, …

Distributed Fibre Optic Sensing to Assess Support Reactions and Behaviour of Composite Steel Bridges
… beam, model bridge, and field load tests. Five steel beams were instrumented with fibre optic sensors and loaded in simply supported and continuous beam configurations. Disturbed regions in DFOS strain measurements were found to extend a distance equal to the depth of the section from supports …

Static push-out tests and finite element studies on larger diameter shear studs for composite steel bridges
Efficient steel bridge girder design makes use of composite action between the concrete bridge deck and the steel girders. The critical link between the deck and the girders are shear studs welded to the girder top flange. The most commonly used shear studs have a 7/8-inch diameter and are welded …
