Abstract
This paper reports investigation results of three large roof buildings whose non-structural components had failed during the earthquake in Suruga-Bay of Japan in August 11th of 2009. While very little damage to building skeletons was reported, a number of failures of non-structural components such as a big louver, ceiling panels, and lightings was came out. Such failures occurred even in the area where the occurrence of a major earthquake had been geologically estimated. Because a risk of injury to people by falling of non-structural components is urgent, their improvements are immediately necessary. [This abstract is not included in the PDF]
