A coupled study of soil-abutment-superstructure interaction
This paper presents a coupled numerical modelling of the soil-structure interaction for a multi-span girder bridge, inspired by a case study in Italy, to analyse the importance of the local dynamic response of the abutments in the seismic performance of the bridge. The full soil-bridge model was implemented in the analysis framework OpenSees, describing the mechanical behaviour of the foundation soils by means of an advanced constitutive model calibrated against experimental data.
