Investigation of the appticability of dynamic loads acting on pile foundations as static loads

In this study, the applicability of the dynamic loads acting on floating pile groups in liquefied soils as static loads is studied. The group pile deformations under dynamic effects are modelled by the Plaxis software dynamic module and the equivalent static loads that cause the same deformations on pile group are determined by back-calculations.As a result, in the case of not using programs that consider the dynamic effects, dynamic forces can be considered as static loads to design of the pile foundations in liquefied soils. Total vertical loads applied to the pile foundations can be increased 100% to consider the earthquakes up to magnitude of 6,0. Total vertical static loads applied to the pile foundations can be increased 200% to consider earthquake loads between 6,0~8,0.Key words: Pile Foundations, Friction Piles, Earthquake, Liquefaction, Plaxis
