Elucidation of Dynamic Behavior of Super High-Rise Residential Buildings during Massive Earthquake and Activities for Mitigation of Seismic Damages in Future

Abstract

This paper summarizes our activities for elucidation of dynamic characteristics of super high-rise residential buildings during the 2011.3.11 Tohoku Earthquake and for mitigation of seismic damages during the future massive earthquakes. We organized the "Joint Study Group on Earthquake Observation Records in Super High-Rise Residential Buildings" after the 3.11 Earthquake, where we share information and the outcomes from the analyses of the recorded motions. In addition to that, we carried out questionnaire survey for residents, simulation analyses, mictrotremor measurements, shaking table tests, etc, toward comprehensive understanding of what happened during the 3.11 Earthquake. The obtained results will be available for mitigation of seismic damages during the future massive earthquakes. We must emphasize, last but not least, that strong motion observation in building is inevitable in terms not only of post-earthquake damage evaluation, but of services for residents in related with the life continuity planning.
