isolation, have shown promise as effective solutions to mitigate damage to
vital equipment housed within mission-critical facilities, such as
telecommunication centers and emergency response centers, thus reducing
business interruption following earthquakes. However, existing equipment
isolation systems suffer from limited displacement capacities, degrading their

passive rolling isolation systems capable of withstanding MCE (maximum
considered earthquake) level events are introduced, with particular attention
to modeling the complex dynamics of these systems. Two advancements are
presented as possible solutions, which include increasing the rolling
resistance and doubling the displacement capacity via a multi-layer isolator
configuration. Ongoing efforts to optimally design these advanced systems are
discussed, and future challenges are presented, including the modeling of impacts
in such systems.</span></p>
