Nonlinear dynamic analysis of pile foundation using finite element method.

ABSTRACT: Nonlinear dynamic response analysis of pile foundations is essential in seismic regions, where soil-pile-structure interaction governs safety and serviceability. Ethiopia's location along the African and Arabian tectonic plates exposes its infrastructure to high seismic risk, demanding rigorous foundation evaluation. This study investigates the pile foundations of Bridge B-40, part of the Awash-Kombolcha-Hara Gebeya railway project in the seismically active Afar Triangle (PGA = 0.3 g). Using PLAXIS 3D, with the Hardening Soil model at small strains and the Hoek-Brown model for rock, site-specific geotechnical and seismic data were incorporated to simulate static and dynamic conditions. Static analysis showed negligible settlement (0.55 mm), with stresses far below capacity. Free-field site
