AASHTO Load Combinations
Fatigue/Strength/Service/Extreme.
Girder Design
Flexure/shear, stiffness, spacing.
Deck Slab
Bar spacing, thickness, cover.
Bearing Checks
Service rotations and pressures.
Substructure Checks
Piers/abutments, loads, stability.
Standards note
Use jurisdictional editions and site-specific loads; confirm fatigue/importance.
