Abstract

Wind and earthquake induced acceleration data has been recorded systematically in a 14 story reinforced concrete building over a period of 20 years during earthquakes and strong storms. The recorded acceleration data is used for system identification of the building. The dataset provides an opportunity to observe, and investigate the variations in natural frequencies (stiffness) and critical damping ratios for the main modes of vibration with time as well as within single extreme events. Short term variations in system parameters are observed as well as a slow increase in flexibility during the whole observation period.
