Geogrid reinforced embankment at Ionia Odos seismic assessment

Assessment of the seismic response of a Geogrid Reinforced Embankment along Ionia Odos (a 196 km motorway connecting Western Greece). We delivered a performance-based earthquake design assuming two levels of earthquake intensity: (i) Design Earthquake (with a return period pf T=500 years) and a moderate event with T=50 years. The performance was assessed by means of a 2D non-linear FE simulations accounting for non-linear soil response (i.e. stiffness degradation, kinematic hardening e.t.c)
