A QUESTIONNAIRE ON SEISMIC INDOOR DAMAGE AND OCCUPANTS’ BEHAVIOR OF TALL RESIDENTIAL BUILDINGS IN TOKYO

Abstract

The authors conducted a questionnaire survey to the residents of super high-rise residential buildings in Tokyo, on the responses of them due to the 2011 off the Pacific coast of Tohoku Earthquake. The important results are: (1) Due to the large shaking amplitude, residents’ behavior was considerably affected. (2) The furniture overturned or moved severely, especially on the upper floors of tall buildings which have less than twenty stories, in the conventional structures’ cases. In the base isolated buildings, the damage was much smaller than that of conventional ones.
