DEVELOPMENT OF OIL DAMPER AND RESEARCH ON ANALYTICAL MODEL WITH CONSIDERATION OF DAMPING CHARACTERISTICS

Abstract

This paper describes development of a new designed oil damper and research depends on various factors on an analytical of it. Recently, oil dampers have been used frequently for reducing vibration of buildings due to earthquakes. They can work as high performance energy dissipation devices. The oil-damper developed in this study can demonstrate damping performance even to small vibration. Therefore, it is not only effective to earthquakes, but also to strong winds or traffic vibrations. This paper explains the concept of the development, the design method, the experiments, the analytical model, and the calculation algorithm.
