This Technical Guidance Note concerns the design of pile-caps for small groups of piles e.g. 2-4 piles. It relies on the strut-and-tie method to determine the amount of reinforcement required in the pile-cap; which is dependent upon the depth of the cap, the magnitude of the axial load being placed upon it, the cap’s concrete strength and the pile size and spacing. Larger pile-caps are influenced by differential settlement across the base, which complicates their analysis and design.
