Abstract

This paper presents system identification of the vibration characteristics for a high-rise building using continuous seismic records. The building is 95m height, plan of a square 30m on a side and it was completed in November 1990. The records of seismic observation have been collected in two horizontal directions and vertical direction on each measuring floor in the building since September 2010. It is identified characteristics of natural frequencies and damping ratios based on continual observation under microtremor, strong wind, and seismic ground motion.
