...In most of the previous models (Vesic, 1961 ; Carter, 1984 ; Bowles, 1988 ; Ling, 1988 ), the modulus of subgrade reaction of the p-y curve K is taken proportional to the soil modulus of elasticity (E s ) and pile diameter (D), and is inversely proportional to the Poisson's ratio of soil (μ) and flexural rigidity of pile (E p I p )....

...Bowles (1996) describes that, in the Lumped Parameter method, the effect of frequency-dependent soil-flexibility on the behaviour of overall structural system is higher than what is obtained from the frequency-independent behaviour determined by Winkler model. The additional damping effect imparted by the soil to the overall system may also be conveniently accounted for in this method of analysis. However, he concluded that the accuracy of this method is not adequate for complex problems. Dutta and Roy (2002) elucidated that the effects of SSI on the dynamic behaviour of structures may conveniently be analysed using the Lumped Parameter approach....

However, he concluded that the accuracy of this method is not adequate for complex problems. Dutta and Roy (2002) elucidated that the effects of SSI on the dynamic behaviour of structures may conveniently be analysed using the Lumped Parameter approach. However, resorting to the numerical modelling may be required for important structures where more rigorous analyses are necessary. Jahromi (2009) concluded that this method cannot deal accurately with geometric and material nonlinearity, hence modelling the non-linear response of both soil and structure becomes complex for which more sophisticated modelling approaches would be required....
