Precast Reinforced ConcreteRC Piles
Design and Specification
- Standard :
- Designed to the BS 8004 : 8110.
- Concrete Strength :
- 45 N/mm2.
- Design Criteria :
- Design and manufactured to withsand loads or stresses due to lifting, stacking, transport, handling, pitching, and driving at site.
- Main Longitudinal Reinforcement is designed for lifting handling and pitching.
- Handling and Pitching :
- Designed to resist bending moment due to single point or two poins lifting / pitching.
Allowable Loads (Safe Working Load)
Calculation for Allowable Loads
Allowable Structural Capasity : 0.275 fcu x Ac + 0.55 fy x As
fcu : Characteristic cube strength of concrete at 28 days = 45 N/mm.
Ac : Area of Concrete.
fy : Characteristic Yield Strength of Steel (with 0.55 fy not exceeding 175 N/mm).
As : Area of Steel.
