StructureCalcsW24X55
Wide-Flange Beam · AISC Shapes Database v15.0 · United States
W24X55 is a wide-flange beam 599.4 mm deep with a 178.1 mm wide flange, weighing 81.9 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 W24X55 the computed area agrees with the published value to 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 | 1,890,174 mm³ |
| Elastic modulus, Sy | 136,289 mm³ |
| Plastic modulus, Zx | 2,220,332 mm³ |
| Plastic modulus, Zy | 219,413 mm³ |
| Radius of gyration, rx | 232.1 mm |
| Radius of gyration, ry | 34.0 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
