000011901 520__ $$2eng$$aAn innovative base isolation system for seismic mitigation of ordinary low-rise buildings is introduced in this paper. The proposed base isolation system utilizes “Stable Unbonded Fiber Reinforced Elastomeric Isolator” (SU-FREI) bearings. The steel plates used in conventional laminated rubber bearings are replaced with fiber fabric in FREI bearings. The fiber fabric is extensible in tension and has no flexural rigidity. In an unbonded application, the FREI bearings are simply placed between the superstructure and substructure with no bonding between the contact surfaces. Results from an experimental study conducted on model scale prototype SU-FREI bearings comprised of unfilled soft Neoprene rubber as the elastomer and bi-directional carbon fiber fabric as the reinforcement show that these bearings exhibit Stable Rollover (SR) deformation and perform as an effective seismic isolation device. The experimentally evaluated lateral load-displacement properties of the proposed SU-FREI bearings have been modeled using an iterative analysis with a simplified mathematical model. Results of time history analysis performed on both a 2-storey prototype base-isolated structure and a corresponding fixed-base structure indicate that the proposed base isolation technique can be employed efficiently in hazard mitigation of low-rise buildings located in high seismic regions worldwide.
