WebApr 3, 2024 · Design Example. A 500mm x 500mm column is carrying an ultimate limit state load of 2140 kN. We are to design the pile cap using the following data; Grade of concrete f ck = 30 N/mm 2. F yk = 500 N/mm 2. Concrete cover = 75mm. Spacing of pile = 1800mm. Diameter of piles = 600mm. WebFeb 1, 2024 · Two methods are commonly used in pile cap design. There are beam theory and truss analogy/method of strut and tie. The pile cap is designed as a beam for internal …
WebFeatures. The design calculation accommodates the basic assumptions of truss analogy (strut and tie method). The check for minimum depth of pile cap is done based on the spacing of piles. The design calculation is carried out for pile cap under the influence of axial load in normal or eccentric conditions, from column. WebThus for a 3 (and 4) pile cap this is not the total amount of steel in the pile cap. It is left to the engineer to decide how to detail the reinforcement and the calculation does not do …
