Fiber reinforced elastomeric isolators for the seismic isolation of bridges

Unbonded fiber reinforced elastomeric isolators (U-FREI) have been proposed as a viable alternative to traditional steel reinforced elastomeric isolators (SREI) for use in low-rise building base isolation systems. The viability of U-FREI for this particular application was confirmed through an extensive evaluation of their lateral response under the condition of no rotational deformations of the loading supports. In order to extend the use of …
