ASG Presentation: “EQ Resilient Structures & Friction pendulum Bearings” by Victor Zayas

Joint presentation with Aurecon

When - Tuesday 12 August 2014

Abstract

A presentation by Victor Zayas of Earthquake Protection Systems (EPS) focussing on the ability and need to design more seismic resilient structures and the use of pendulum bearings.

Resilient structures are achieved by absorbing seismic displacement in isolation bearings, maintaining an elastic structure, and minimizing in-structure accelerations and drifts. Post-earthquake functionality is typically retained when seismic damage is limited to less than 2% of the replacement costs.  Code requirements for isolated structures only intend to prevent collapse, not damage. 

Isolated structures designed for minimum code compliance can have damage equal to 30% to 70% of replacement costs. EPS engineers are the world's leading seismic isolation engineering experts.  EPS developed Friction Pendulum technology protects the world’s most important seismically isolated structures in more than 22 countries.  EPS’s seismic solutions have been selected by the world’s largest corporations and governments, including: Apple, Samsung, Texas Instruments, ExxonMobil, Shell, the USA, Russian, and Chinese National governments, and the States of California, Washington, Oregon, and Alaska. 

About the presenter

Victor is the inventor of the Friction Pendulum, a sliding pendulum concept that minimizes seismic damage to structures. Victor is also the primary inventor of the Triple Pendulum, the first multi-stage seismic isolation system for protecting non-structural components and facility contents from seismic damage.
