Piled rafts are unique foundation solutions due to their load sharing behavior between their foundation elements such as pile and raft. The estimation of differential settlement and angular distortion are critical design parameters for piled raft design. In the present study, the effect of soil–raft stiffness (Krs) on the performance of small piled raft subjected to vertical loading in a cohesive medium has been presented through validated three-dimensional finite element-based numerical analysis. The Krs of the foundation is dependent upon several factors such as material properties of the raft and soil and the geometry of the raft. The Krs has been evaluated for different raft thicknesses and various grades of concrete replicating different concrete strengths. The influence of Krs on load sharing, differential settlement, and angular distortion has been discussed in detail. The pile load sharing increases in the range of 2–14% with increasing pile spacing from 2 to 8D, respectively. The angular distortion decreases in the range of 20–62% with increase in the Krs in the range of 4–18 respectively. The differential settlement and angular distortion in a piled raft foundations are in permissible limit for soil–raft stiffness greater than 9.
