报告简介 (Outline) :

Protective technologies such as seismic isolation deliver significantly increased performance. However, there are still hurdles for their widespread adoption, including limited knowledge about their ultimate level performance, familiarity in practice, and increased upfront project costs. This talk will cover recent research directed at addressing these issues. To maximize the benefits of isolation, systems must be designed to have optimum behavior over all earthquake levels. Protective systems can be developed to have different characteristics at different levels of shaking. As one example, the triple friction pendulum (TFP) isolation bearings has a multi-stage backbone behavior which achieves multiple performance objectives: it reduces costs due to nonstructural content damage under frequent events; it reduces downtime and disruption from structural repair under moderate to large events; and under extreme events, it maintains life safety. To increase the reliability of isolated systems, we must have a better idea of their performance in beyond-design events. Recent testing on the extreme behavior of friction pendulum bearings will be presented as well as how this information affects our knowledge on the probability of collapse of an isolated structure and how capacity design should be applied for isolated structures.

 报告人简介 (About the Speaker) :

Tracy Becker is an assistant professor at McMaster University in Hamilton, Canada. She has expertise in the design, modeling, and experimental testing of high-performance structural systems. Her research group at McMaster focuses on expanding the use of seismic isolation to a broader category of structures, understanding ultimate failure mechanisms of isolated structures to ensure robust designs, and improving existing control systems to further minimize structural responses in seismic events.  She received her BS in Structural Engineering from University of California, San Diego and her MS and PhD in Structural Engineering, Mechanics and Materials from University of California, Berkeley. After graduation she was a post-doctoral researcher at the Disaster Prevention Research Institute at Kyoto University.
