Using Base Isolators in Bridges to Reduce the Dynamic Forces of Piers and Abutments, M.Sc. Thesis Sharif University of Technology ; Jahanshahi, Mohsen (Supervisor)
Abstract
In recent years, the application of base isolation as a seismic design strategy for reducing the effects of earthquake ground motion has become an advantageous method and much effort has been devoted to base isolation research and there has been a growing acceptance of this approach. In this research, the effect of using base isolators in reducing the dynamic forces of piers and abutments of bridges is studied. More specifically double-span bridges are the target of this research. After modeling a regular bridge in a typical analysis program, it is excited by different earthquake accelerograms and then the effect of using base isolators in dissipating the earthquake energy is investigated
