Vibration Control of High-Rise Buildings Using High-Damping Rubber Damper : 3rd Report, Temperature Dependency and Durability of Cylinder Type High-Damping Rubber Damper

Abstract

A new type of high-damping rubber damper for vibration control of tall buildings has been being developed in this study. This paper describes the temperature dependency of the damper which will be an important problem in vibration control systems using high molecule material. The tests were carried out in two different conditions from the viewpoint of the temperature variation of vibration control material into the dampers. One is the variation of environmental temperature around the damper and the other is the self-generated heat in the damper which will be induced by the cyclic loading such as earthquake or wind. Moreover, the durability of damper was investigated by following tests; breaking test, static tests and cyclic loading tests under excessive shear strain amplitude. As the results, it was confirmed that the temperature dependency of the damper would not much affect to the energy absorbing characteristics even in the case of the practical use and the durability of the damper was highly enough against the large earthquakes by means of its strong adhesive characteristics.
