Abstract
AbstractFiber‐reinforced elastomeric isolator (FREI) is a new generation of seismic isolation device in which steel plates are replaced by fiber reinforcement. The essential characteristic of the elastomeric isolator is a very large ratio of the vertical to horizontal stiffness. This is somehow provided in FREI by resembling to steel reinforced elastomeric isolators (SREI). In this work, a comparative experimental analysis is presented to evaluate the performance of fiber‐reinforced nanocomposite elastomeric isolator (FRNEI) with FREI. FRNEI was manufactured based on nanocomposite rubber compound. The results clearly indicate an increase of 20% in the ratio of the vertical to horizontal stiffness for FRNEI when compared with FREI.
