Analytical Fragility Curves of Pile Foundations with Soil-Structure Interaction (SSI)

Pile foundations is a well-studied technique with many applications and its benefits on structures have been widely studied in the literature. In particular, mutual effects of pile flexibility soil deformability may significantly modify seismic behaviour superstructures. order to consider uncertainties that are connected these issues, paper applies probabilistic-based approach fragility curves by proposing three limit states based ductility factor. Non-linear dynamic analyses were performed OpenSees PL assess potentialities configurations founded cohesionless different deformability.
