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.
