Archivio Istituzionale della RicercaThe present study focuses on the analysis of the seismic performance of isolated bridges, equipped with single concave friction pendulum (FPS) bearings. The bridge is modelled through a six-degree-of-freedom system considering two FPS bearings placed on top of the rigid abutment and the elastic pier. The six equations of motion are analytically solved in order to obtain the response parameters normalized with respect to the peak ground acceleration-to-velocity ratio (PGA/PGV). In addition, a parametric analysis is conducted by varying some bridge properties. All these different bridges are then subjected to a set of 30 far field records having low and high PGA/PGV ratios to assess the seismic performance.

Abstract
The present study focuses on the analysis of the seismic performance of isolated bridges, equipped with single concave friction pendulum (FPS) bearings. The bridge is modelled through a six-degree-of-freedom system considering two FPS bearings placed on top of the rigid abutment and the elastic pier. The six equations of motion are analytically solved in order to obtain the response parameters normalized with respect to the peak ground acceleration-to-velocity ratio (PGA/PGV). In addition, a parametric analysis is conducted by varying some bridge properties. All these different bridges are then subjected to a set of 30 far field records having low and high PGA/PGV ratios to assess the seismic performance.
