Increased flexibility due to compliance of the extended pile-shaft supported bridge foundation can be observed under dynamic loadings, where the severity of the lateral displacement could cause structural collapse from plastic hinge formation along the height of the subsection of the bridge. Therefore, accounting for soil-structure interaction (SSI) becomes fundamental for the design of extended pile shaft type bridges.

This project undertook both experimental and numerical incremental dynamic analysis of cantilever and SSI models. This produced experimental IDA curve and acceleration X-Y curves allowing demonstration of the plastic hinge formation.
