摘要
For the past several years, large scale earthquakes happened. A lot of industrial facilities were damaged. For example, a lot of power plants were stopped in The 2011 off the Pacific coast of Tohoku Earthquake or The Southern Hyogo prefecture earthquake in 1995. These earthquakes have larger acceleration level than the seismic design level. Therefore, the earthquake proof measures are required. There are many dampers as the energy dissipating device. For example, oil damper, visco-elastic damper, magnetic damper, friction damper, elasto-plastic damper, and so on. The friction damper and elasto-plastic damper are utilized for the large scale earthquake. This paper deals with the response reduction effect by elasto-plastic behavior. Elasto-plastic behavior is expected to absorb the seismic energy. In this paper, R-O model are focused as the elasto-plastic model. There are two types of elasto-plastic behavior. One is elongation type and the other is elongation-compression type. At first, the comparison of the characteristics of these types is taken place. Next, the seismic response reduction effect is clarified. © 2013 The Japan Society of Mechanical Engineers.
