Wide-Flange Beam · AISC Shapes Database v15.0 · United States
W14X665 is a wide-flange beam 548.6 mm deep with a 449.6 mm wide flange, weighing 989.6 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 the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For W14X665 the computed area agrees with the published value to better than 0.01% and Ix to 0.21%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 18,854,389 mm³ |
| Elastic modulus, Sy | 7,781,202 mm³ |
| Plastic modulus, Zx | 24,266,245 mm³ |
| Plastic modulus, Zy | 12,026,403 mm³ |
| Radius of gyration, rx | 202.2 mm |
| Radius of gyration, ry | 117.6 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
