StructureCalcsW40X235
Wide-Flange Beam · AISC Shapes Database v15.0 · United States
W40X235 is a wide-flange beam 1,008.4 mm deep with a 302.3 mm wide flange, weighing 349.7 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 W40X235 the computed area agrees with the published value to better than 0.01% and Ix to 0.13%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 14,383,449 mm³ |
| Elastic modulus, Sy | 1,228,534 mm³ |
| Plastic modulus, Zx | 16,630,549 mm³ |
| Plastic modulus, Zy | 1,949,271 mm³ |
| Radius of gyration, rx | 403.3 mm |
| Radius of gyration, ry | 64.5 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
