Structural Steel I-Beam Wide-Flange Shapes (W-shapes) Table
Cross-sectional properties for standard AISC wide flange steel shapes including depth, area, and moments of inertia.
Overview & Scope
Wide flange W-shapes represent standard I-beam steel sections sourced from the AISC Shapes Database v16.0 (American Institute of Steel Construction). Moments of inertia (Ix, Iy) dictate cross-section stiffness limits under transverse bending loads.
Technical Sizing Values
The table below specifies nominal dimensions, cross-sectional areas, and moments of inertia for standard W-shapes per AISC Shapes Database v16.0 and the AISC Steel Construction Manual (16th Edition).

Engineering Notes & Best Practices
- •Cross-section dimensions and section properties strictly align with AISC Shapes Database v16.0.
- •Moment of inertia Ix represents structural resistance to bending about the major axis.
- •Moment of inertia Iy represents structural resistance to bending about the minor axis.
- •Flange and web local buckling checks should be verified when beams are subjected to high compression loads.
