Universal Bearing Pile · AS/NZS 3679.1 · Australia / New Zealand
310 UBP 149 is a universal bearing pile 318.0 mm deep with a 316.0 mm wide flange, weighing 148.6 kg/m. The dimensions below are the published AS/NZS 3679.1 values; the drawing is generated from them.
Universal Bearing Piles keep flange and web at the same thickness for driving — near-square I-sections that take soil abrasion and hard driving on both faces.

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 310 UBP 149 the computed area agrees with the published value to better than 0.01% and Ix to 0.15%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Zx | 2,067,991 mm³ |
| Elastic modulus, Zy | 687,237 mm³ |
| Plastic modulus, Sx | 2,360,106 mm³ |
| Plastic modulus, Sy | 1,060,855 mm³ |
| Radius of gyration, rx | 131.8 mm |
| Radius of gyration, ry | 75.7 mm |
Z is the elastic modulus and S the plastic modulus, following AS 4100. Under AISC 360 the letters are reversed.
