Pile footings may be square or rectangular in shape, but may also be which other shapes depending on the number of piles in the group or the arrangement?

Pile footings may be square or rectangular in shape, but may also be which other shapes depending on the number of piles in the group or the arrangement?

• A. Triangular, hexagonal, or octagonal
• B. Circular
• C. Pentagonal
• D. Ribbon-shaped

Answer: (A)

Pile caps are shaped to fit the layout of the piles they tie together. When piles are arranged in patterns other than a simple rectangle, the cap follows that pattern. For three piles, a triangular cap fits the arrangement; for six piles arranged around a center, a hexagonal cap is efficient; for eight piles in an octagonal layout, an octagonal cap makes sense. This geometry helps distribute the load evenly among piles and keeps the reinforcement practical around the cap.
