Full-Scale Measurements on Vibrations of a 51-Story Tall Building Due to a Major Earthquake and Typhoon

Abstract:

The Shin Kong Tower located in Taipei City has a height of 244.15 m. It was the tallest building in northern Taiwan when it was built in 1993. This super tall building is susceptible to severe vibrations induced by strong winds or earthquakes. Safety of the building structures and its contents as well as the comfort of its occupants under such strong forces remains a significant engineering concern. Records by a structural array in the 51-story SK Building of the 1999 M7.6 Chi-Chi earthquake and 2004 Typhoon Aere are analyzed in this study. As a result, the structural dynamic characteristics of the high-rise building, including the transfer functions and natural frequencies, excited by the Chi-Chi earthquake, Typhoon Aere, and ambient vibrations are also determined and compared.
