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.
