Vulnerability Assessment of Pile Foundation in Soft Clay Incorporating SPSI
Past failures of pile foundation supported structures during moderate to severe earthquake had lead earthquake professionals to develop sustainable design guideline. Dynamic soil-structure interaction (DSSI) is considered as an important phenomenon in seismic design as it leads to increased or decreased response that of conventional fixed base design. On the other hand, the variability of subsoil properties and ground motion influence the dynamic response of structure. In this context, the present study attempts to assess the seismic vulnerability of pile foundation embedded in soft clayey layer by developing fragility curves incorporating both material and ground motion uncertainty. Finite element model of soil-pile-foundation-structure system is modeled using OPENSees software. Total 0.36 million nonlinear dynamic analysis of the whole system are performed to obtain the probabilistic response of pile foundation. Monte–Carlo simulation is performed to calculate the probability of failure, and finally multiple strip analysis technique is used to construct fragility function. Results indicate that the probability of failure is higher pertaining to serviceability limit state as compared to collapse criteria.
