IMPOSSIBILITY RATIO OF EVACUATION IN SUPER HIGH-RISE RESIDENTIAL BUILDINGS BASED ON QUESTIONNAIRE SURVEY AFTER THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE AND SHAKING TABLE TESTS

Abstract

This study investigates the impossibility ratio of evacuation in super high-rise residential buildings during an earthquake. Shaking table tests using the strong motion records observed in super high-rise residential buildings during the 2011 off the pacific coast of Tohoku earthquake were performed. Then, the questionnaire survey about action difficulty during the shaking was conducted for the testee. Finally, the evaluation method about impossibility ratio of evacuation during earthquake was proposed based on the questionnaire survey and strong motion data recorded during the main shock.
