INDOOR DAMAGES OF SUPER HIGH-RISE RESIDENTIAL BUILDINGS DURING THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE BASED ON STRONG MOTION RECORDS AND QUESTIONNAIRE SURVEY

- Study on anxiety, action difficulty and overturning ratio of furniture -

Abstract

This study investigates the relationship between the strong motion records of super high-rise RC residential buildings and the indoor damages during the 2011 off the Pacific coast of Tohoku earthquake based on a questionnaire survey. The indoor damages, including the anxiety, the action difficulty and the overturning ratio of furniture were discussed in comparison with previous studies. The following conclusions were reached; 1) Levels of the anxiety and the action difficulty were greater than results in Takahashi et al. (2010) based on shaking table tests. 2) The overturning ratios of furniture were fairly consistent with Kaneko et al. (2002). 3) At the acceleration and the velocity which the overturning ratio of furniture starts to increase, most of residents felt difficulty in moving.
