PERFORMANCE OF THE SUPER HIGH-RISE SEISMICALLY ISOLATED BUILDING DURING THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE

Abstract

Performance of the super high-rise seismically isolated building during the Great East Japan Earthquake was reported. The response acceleration of the top floor was almost same as that of the 1st floor. The maximum displacement of the isolation devices was 15 cm, and the cumulative displacement was about 10 m. The dynamic response analysis, considered variation of the characteristic of rubber bearing, ambient temperature and so on, was coincident with observed records.
