StructureCalcsW14X426
Wide-Flange Beam · AISC Shapes Database v15.0 · United States
W14X426 is a wide-flange beam 475.0 mm deep with a 424.2 mm wide flange, weighing 634.0 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
W-shapes are the American wide-flange family — the default beam and column of US practice, with parallel flanges and the widest range of depths in the AISC catalogue.

Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For W14X426 the computed area is 0.21% from published and Ix 0.28%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 11,599,441 mm³ |
| Elastic modulus, Sy | 4,645,076 mm³ |
| Plastic modulus, Zx | 14,255,229 mm³ |
| Plastic modulus, Zy | 7,129,759 mm³ |
| Radius of gyration, rx | 184.6 mm |
| Radius of gyration, ry | 110.4 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
