Pile foundations are provided to transfer loads from superstructures through weak, compressible layers of soil onto more competent and less compressible soil or rock at greater depths. However, in the past two decades, the concept of piled-raft foundation has gained momentum as it utilizes both the raft and piles as a load transfer, and settlement reducer element and gives a better utilization of the overall foundation system. The conventional approach for designing of pile foundations is normally based on the bearing capacity method, which sometimes does not provide information on the load distribution along the depth and across pile locations beneath a pile cap. Therefore, in order to obtain an acceptably accurate response of a structure founded on a pile and piled-raft system subjected to static load, an attempt has been made to validate a finite element-based approach using non-linear pile-soil spring, especially keeping practicing structural engineers as the target group. The non-linear spring for piles consists of three components i.e., skin friction ( \(t-z\) ), end bearing ( \(q-z\) ) and lateral stiffness of the soil ( \(p-y\) ). A detailed review of the available spring formulations for pile subjected to lateral load have been carried out followed by validation of the selected simplistic model by comparing the experimental and earlier numerically simulated response for single piles subjected to vertical and lateral load. After that, the work presents a comparative case study, using the selected simplistic model, for a piled-raft system subjected to lateral load. This is further extended for a parametric analysis in a multi-storied structure with various configurations and layouts of piles. The conclusion has been drawn based on the application of the chosen model and limitation has been figured out as future scope.
