Preliminary Research on the Response of Steel Structures During Off Pacific Coast Tohoku Earthquake on 11^th March 2011 Using a Weather Camera

Abstract

Steel structures had experienced a big response for a long time caused by the great earthquake motion during the Off Pacific Coast Tohoku Earthquake. Lots of non-structural damages and many videos shot in many places are the characteristics of this earthquake. Some opened earthquake records and videos are used in this study in order to investigate the earthquake response of the steel structures. An application of vision-based method has been carried out on a video shot by Japan Broadcasting Corporation (Nippon Housou Kyoukai) of high-rise buildings at Shinjuku, Tokyo during Off Pacific Coast Tohoku Earthquake on 11th March 2011.
