ABSTRACT

Philip Scott Harvey Jr, PhD
PE Assistant Professor, University of Oklahoma

Passive protective measures, such as seismic 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 performance under extreme
seismic events.

In this seminar, the challenges in designing 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.
