Abstract
The viscous anti-seismic devices, also called “viscous dampers”, are frequently used to improve the seismic response of structures and in particular of bridges. Unlike other anti-seismic devices, the viscous dampers are characterized by a considerable damping and yield capacity which allows to dissipate a rate of energy induced by the seismic action and to contain, together with the displacements, also the stres- ses that arise in the structural elements. Due to their performance characteristics, the viscous dampers have been used within a huge seismic retrofitting project of an Italian bridge located on A14 highway Bologna- Taranto in the Abruzzo Region, which is the case study outlined in this paper.File | Dimensione | Formato | |
