Throughout the past few decades, the use of combined pile raft foundations to support high-rise buildings has seen noticeable growth. Popularity has been gained by the economic advantages of piled raft foundations over alternative methods, but this comes with added complexity for load-sharing calculations when a few variables are associated with it. In the present study, five different densities, viz., very loose, loose, medium, dense, and very dense of sand, have been kept to focus on the behaviour of load-sharing ratio between pile and raft of piled raft foundation. ‘ABAQUS’ finite element-based software has been used to analyse the pile raft foundation system. Load-sharing ratio has been calculated based on parametric variation such as length-to-diameter ratio of pile, raft thickness, and spacing to diameter ratio pile raft foundation system. However, for the calculation of load-sharing ratio, vertical stress (S22) is taken from a different elevation, such as just below of raft, top of the pile, and bottom of the pile. The load–settlement curve shows that load-carrying capacity pile increases with the increase in relative density of sand. As a result, load-sharing by raft increases while pile-sharing reduces as the relative density of sand increases; at very dense conditions, load-sharing by pile and raft is nearly equal. It is also observed that the maximum proportion (75–90) % of the load transfer through the shaft bearing of the pile to the total pile-sharing, and the rest are taken by the end bearing of the pile.
