Influence of Soil-Structure Interaction on Yielding of Pile Embedded in Stratified Soil
The safety and serviceability of an engineering structure rely on the prediction of response and failure mechanism of the structure. The accurate prediction of the response of the structures subjected to earthquake loading is a difficult and great concern of the researchers. The prediction of response of pile foundations which are surrounded by different soil types throughout their length becomes difficult due to the complex soil-structure interaction mechanism during earthquake. This has led to the failure of many structures due to earthquake. This further emphasizes the importance of the non-linear soil-structure interaction for designing pile foundations. The pushover analysis is a static non-linear seismic analysis which can be used to predict the seismic response of the pile foundation with the incorporation of soil-structure interaction. In this research work the modeling of the pile-soil system is done in OpenSees PL, a user-friendly interface of OpenSees. The piles embedded in layers of cohesionless and cohesive soil having different relative densities and layer thickness are pushed to a pile head displacement of 2% of pile length. From the response of pile obtained from pushover analysis, the yield moments are determined. The yielding moment generated in pile is influenced by the stratification of soil. The density of the soil and soil type influences the yield moment generated in pile.
