N2 - The present study describes the evaluation of feelings of difficulty faced by residents in performing actions during earthquakes (hereinafter, action difficulty) based on questionnaire surveys and strong-motion records for high-rise RC residential buildings having over 20 stories with seismic dampers or seismic isolation devices applied. In the recent structural design of buildings, both ensuring structural safety, such as the preservation of human lives during earthquakes, and evaluating the security of people in the buildings from the viewpoint of resilience, such as their continuous functionality and reduction of anxiety, are necessary. In the present study, focusing on the degree of the action difficulty, we propose a new evaluation formula based on the results of questionnaire surveys during earthquakes to evaluate the security of people in buildings. First, we analyze past questionnaire survey results in detail for the residents of high-rise residential buildings and show that the action difficulty is greatly reduced in seismically isolated buildings, as compared to earthquake-resistant buildings. On the other hand, for seismic response controlled buildings with steel dampers, no significant effect is determined in terms of action difficulty based on questionnaire surveys after massive earthquakes. Second, based on the relationship between the strong-motion records and the results of questionnaire surveys for the residents of high-rise buildings for the 2011 off the Pacific coast of Tohoku earthquake, we propose a new evaluation index to evaluate the security of people in the buildings and develop an evaluation formula for action difficulty. Third, we construct three-dimensional frame models with seismic dampers or seismic isolation devices in an existing high-rise RC residential building and evaluate the action difficulty for residents on each floor based on the proposed formula. Finally, we evaluate action difficulty during a medium-scale earthquake. The results indicate that the application of oil dampers and seismic isolation devices contributes to improving the security of people in buildings.
