The forces acting on a pile cap are applied to the foundation at the foundation level. The foundation can take axial load and bi-axial shear and moment.

Pile cap design is divided between the pile design (pile axial and lateral capacity checks) and the structural design of the pile cap which includes bending, shear and punching shear design checks.

Pile cap calculations are performed in accordance with BS EN 1992-1-1:2004 (Ref. 1).

Bottom reinforcement is designed to the Eurocode - (EC base, UK NA, Irish NA, Singapore NA or Malaysia NA).
