Analysis of combined piled raft foundation proves to be an effective tool to bear the stresses and reduce the settlement of the foundation. Efforts have been made to optimize the parameters of pile raft foundation. In order to find economical solution various parameters like spacing of piles and the load imposed on foundation are varied to obtain optimum results. A finite element model of combined piled raft foundation is simulated in SAP-2000 to examine the performance of foundation under various loading conditions. Springs are assigned by discretising the model to simulate soil properties. The model is being validated by comparing result with standard book. This study could be helpful and serve as a guideline for the variation in other parameters like pile length, pile shape, raft thickness and several soil properties.
