StructureCalcsW36X330
Wide-Flange Beam · AISC Shapes Database v15.0 · United States
W36X330 is a wide-flange beam 957.6 mm deep with a 421.6 mm wide flange, weighing 491.1 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 W36X330 the computed area agrees with the published value to better than 0.01% and Ix to 0.08%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 20,271,477 mm³ |
| Elastic modulus, Sy | 2,791,451 mm³ |
| Plastic modulus, Zx | 23,092,016 mm³ |
| Plastic modulus, Zy | 4,331,383 mm³ |
| Radius of gyration, rx | 394.0 mm |
| Radius of gyration, ry | 97.0 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
