Abstract
The use of piled raft foundations for tall buildings has been increasing in this decade as it is an economical alternative to the conventional piled foundations. Soil structure interaction is one of the factors governing the behaviour of the foundation. When the raft is subjected to non-uniform loadings, the differential settlements and tilting will be of great importance. The use of different sizes of piles under a non-uniformly loaded raft can reduce the settlements and tilts. Finite layer techniques are used for the analysis of piled rafts. The behaviour of raft supported by different lengths of piles and subjected to non-uniformly loads in both horizontal and vertical directions will be examined.
