This study examines the dynamic properties extracted from a suite of reinforced concrete buildings in South Korea, with emphasis on the performance of system identification approaches applied to short duration ambient records. The resulting extracted properties are then analyzed to identify trends relating damping and frequency to parameters characterizing the structural system and building geometry to highlight underlying behaviors and establish predictive tools suitable for use in the design
