Abstract
Japan is earthquake-prone country. Over 20,000 people were dead by South Hyogo Earthquake in 1995 and Tohoku Pacific coast Earthquake in 2011. Falling of furniture causes human damages of about 40 [%] by these earthquake. It is important to avoid overturn of furniture. However, conventional devices are not popular. The reason is difficulty with installation. Even if these devices are installed, an effect may not be shown. For these reason, a device which is easy to install and effective. In this study, authors are developing new device which improves these problems. The new device is one kind of a tension rod. This new equipment has a damper．Authors examined the effectiveness of the furniture fall prevention device by using damper. In addition, the furniture was modeled to expect behavior during earthquakes. Authors experimented and compared experimental results with analysis results. As a result, authors confirmed the validity of this model. Using this analytical model, seismic response analysis using observed seismic wave was carried out. Analysis conditions were set assuming actual furniture. As a result, furniture fall prevention device is effective even if actual earthquake. However, the device loads strongly on ceiling by occurring force. Therefore, we found the problem to make the device better.
