Pile Load Capacity
Geotechnical IS 2911:2010~2 min
Calculate the axial load capacity of a bored/driven pile using static formula.
Formula
Qu = Qb + Qs = qb·Ab + fs·As
Input Parameters
Results
Pile Tip Area
0.2827m²
Pile Surface Area
22.62m²
End Bearing Capacity
565.5kN
Skin Friction Capacity
1,131.0kN
Ultimate Pile Capacity
1,696.5kN
Allowable Pile Capacity (FOS=2.5)
678.6kN
Step-by-Step Method
- 1Calculate pile tip area Ab = π/4 × D².
- 2Calculate pile surface area As = π × D × L.
- 3End bearing Qb = qb × Ab.
- 4Skin friction Qs = fs × As.
- 5Ultimate capacity Qu = Qb + Qs.
- 6Allowable capacity = Qu / FOS.
Engineering Notes
- •FOS = 2.5 for combined end bearing + skin friction.
- •Refer IS 2911 for detailed design.
