11. Superstructure Code Checks

This section applies the code check templates to verify superstructure components per AASHTO LRFD 9th Edition.

Run code checks after the analysis is complete. Results show demand/capacity ratios for each limit state.

Superstructure Code Checks

Check	Description
Steel I Girder Code Check (AASHTO)	Flexure, shear, and fatigue verification
Bolted Field Splice Code Check (AASHTO)	Splice connection capacity
Cross Frame Code Check (AASHTO)	Bracing member verification
Shear Stud Code Check (AASHTO)	Composite connector capacity

Checks Performed

Steel I Girder

• Flexural strength (positive and negative bending)
• Shear strength
• Fatigue and fracture
• Constructibility
• Service limit state (permanent deformations)

Field Splice

• Bolt shear and bearing
• Plate capacity
• Block shear

Cross Frame

• Tension and compression member capacity
• Connection capacity

Shear Stud

• Fatigue resistance
• Strength at ultimate limit state
