S 2 HM practice and lessons learned from the 2011 tohoku earthquake in Japan

Abstract

During the 2011 Tohoku earthquake, a vast number of buildings suffered violent shaking that has never been experienced in the past. Strong motion data of the 2011 Tohoku Earthquake were obtained in many buildings, and many meaningful analytical results have been reported. We introduce several findings obtained through the analysis of the strong motion data recorded in buildings such as; change in dynamic characteristics of damaged buildings, amplitude-dependence of dynamic characteristics, and long period long duration strong motion and response of tall buildings. In addition, we report the application of the real-time S 2 HM (real-time building damage assessment system) to emergency management in high-rise buildings during the Tohoku earthquake.
