A FUNDAMENTAL STUDY ON DEVELOPMENT OF A VERIFICATION SYSTEM FOR EARTHQUAKE-PROOF MEASURES FOR FURNITURE
It is clear from several past disasters caused by strong earthquakes that many people are injured or killed by the sliding and falling over of big pieces of furniture. This is an important problem that needs to be dealt with as furniture is around all of us, both at home and in the workplace. Up to the present, many kinds of equipment and means of earthquake-proofing with furniture have been studied and developed throughout the world. Although,there are still many people in the general public who are completely unaware of such furniture-related earthquake-proofing measures and their use and effectiveness. As a fundamental study a piece of furniture is assumed as a rigid body in this discussion. From the results of analysis of rigid body subjected to strong ground motion, it was found that to reduce the response of rigid body, increase of static frictional coefficient is effective by setting up frictional sliding stoppers and so on, placed under an article of furniture. In addition sway-rocking simultaneous behavior was simulated here and a regression equation of critical aspect ratio (b/h) for turnover of a rigid body was formulated with amplitude and frequency of sinusoidal acceleration. This equation can be used to estimate whether a body under strong earthquake will turnover or not.
