Summer 2026 Webinar
RESPONSE SPECTRUM METHODS IN EARTHQUAKE ENGINEERING
Tuesday, 8.11.2026
12pm-1pm PDT
Virtual Event
The response spectrum analysis method is widely used for determining the response of linear structures to earthquake ground motions. Many codes of practice recommend the CQC (Complete Quadratic Combination) modal combination rule for this purpose. In this talk, Dr. Armen Der Kiureghian will describe the assumptions behind this method and provide its advantages and shortcomings. He will then describe extended versions of this method for (a) structures subjected to multiple components of ground motion, (b) structures with multiple supports (e.g., bridges), (c) structures with high-frequency modes, and (d) non-classically damped structures. Examples for each case will be presented.

SPEAKER
Dr. Norman Abrahamson
Adjunct Professor, University of California, Berkeley and University of California, Davis
Dr. Abrahamson is an internationally-known expert in seismic hazard and risk analyses, with a focus on the practical application of engineering seismology to the development of deterministic and probabilistic seismic criteria for engineering design and evaluations of seismic risk. He has been involved in developing or reviewing design ground motions for hundreds of critical infrastructure projects around the world. He is an adjunct professor at UC Berkeley, and UC Davis, where he teaches a graduate course on seismic hazard analyses, development of design time histories, and seismic risk. His current research is focuses on non-ergodic ground-motion and fault rupture models, treatment of aleatory variability and epistemic uncertainty in site response, numerically efficient methods for evaluating seismic hazard for complex source and ground-motions, and decision making using hazard or risk estimates with large epistemic uncertainties.
