An Innovative Friction-Based Seismic Isolator Utilizing Bridge Approach Embankments
Abstract An unconventional fusing mechanism reducing the longitudinal response of earthquake resistant bridges is presented. The suggested mechanism is an economical alternative to seismic isolation practice consisting of a concrete slab, connected to the bottom flange of the deck, embedded in the approach fill. The system resists to the deck seismic movements through friction forces developed at both ends of the bridge between the surfaces of the slab and the adjacent crushed material of the embankment. The performance of the proposed mechanism is investigated and a methodology for use with a dynamic response spectrum analysis is suggested and implemented. Furthermore, an experimental investigation was conducted for two loading speeds of a test specimen at a simple but realistic setup. Results of this very promising low-cost “damper” are presented.
