Abstract:

It is well known that the earthquake response of a pile-supported structure is strongly affected by the dynamic soil-pile interaction. In this paper, a three-dimensional soil-pile-a degree of freedom structure system with different stiffness is established by using sap2000 software to evaluate the effects of soil-pile-structure interaction in response of one degree of freedom structure. Nonlinear dynamic behavior of soil is modeled using Winkler Non-Linear model based on P-Y curves in the form of spring-damper systems. For this purpose, non-linear link elements in the software were used that p-y behavior of nonlinear springs is modelled by Multilinear-plastic links with Kinematic hysteretic behavior also, radiation damping is modelled by damper-bilinear element in sap2000 software that for modelling, the combination of these elements (spring-dampers in parallel) are used at a distance of 1 meter in length piles. The results showed that, considering soil-structure interaction in the dynamic analysis of the structure makes the period increases, which this increase in structures with various stiffness is different. Whatever structure-to-soil-stiffness ratio is more the increase in the period is more. From Comparison of the Acceleration response spectra of Tabas, El Centro and Loma Pierta earthquakes with 5% damping, we conclude that Structural response with considering the soil-pile-structure interaction and not, within the period of , are Close together and within the period of , are almost the same, Because of the high period of the structure that has high flexibility.
