Step 4: Analyse and design the pile cap. The required thickness of the pile cap is usually estimated from the diameter of the piles. h = 2 x diameter of piles + 100 = 2(900) + 100 = 1900 mm deep pile cap. Different approaches can be used for analysing the pile cap such as bending theory, strut and tie method, or finite element analysis.
