The need to model the behaviour of piled foundations during serviceability state has required a lot of attention paid to analytical methods, in order to consider the interaction between piles and the sorrounding soil. Among the simplified approaches, the concept of"interaction factors"introduced by Poulos (1968) which takes into account the influence of loading on a pile on the settlement of an adjacent pile is relevant. This note aims to develop an analytical expression for the interaction factor, taking into account the soil non-linear response. The expression, relevant for floating rigid piles, is derived assuming a linear variation of shear modulus G with radial distance and finally is used to model the case record of a 5-pile group.
