This section covers the superstructure components of the Steel I Girder Bridge, including the main load-carrying elements and their connections.
Complete each subsection in order. The superstructure builds upon the geometry and properties defined in earlier steps.
Define FEA bearing elements at support locations
Create plate girder definitions with variable dimensions
Add transverse stiffeners for web stability
Define field splices, shear studs, and gusset plates
Model K-frame and X-frame bracing between girders
Define cross-section and concrete deck properties
Bearings: Structural connections between superstructure and substructure
Plate Girders: Main longitudinal load-carrying steel members with variable flange and web dimensions
Stiffeners: Transverse web stiffeners at bearing locations and intermediate points
Field Splices: Bolted connections between girder segments
Shear Studs: Composite action connectors between steel girders and concrete deck
Cross-Frames: Lateral bracing system for load distribution and stability
Concrete Deck: Bridge deck with reinforcement
