Abstract

<p>Long-period ground motion class, as an evaluation method for the action difficulty during the shaking and the indoor damage in high-rise buildings, has been issued by Japan Meteorological Agency in 2013. Applicability of this method based on the absolute velocity response spectra (AVRS) should be validated by the actual floor response records and indoor damages in high-rise buildings. In this study, we propose the evaluation method of the AVRS by taking into account the participation function and variation of the fundamental natural period during the massive shaking. Using the floor response records of super high-rise residential buildings during the 2011 off the Pacific Coast of Tohoku earthquake, the proposed method provides better evaluation of AVRS than the current evaluation method. Relationship between the actual indoor damage and long-period ground motion class is clarified from the equation of the building response and the damage evaluation value based on the questionnaire survey.</p>
