Vibration Control of High-Rise Buildings Using High-Damping Rubber Damper. 2nd Report, Loading Tests and Design Formula for Cylinder-Type High-Damping Rubber Damper.

This paper describes high-damping rubber damper used for vibration control of high-rise buildings. This damper aims at decreasing the wide vibration range from earthquake motion to wind-induced vibration input to a high-rise building. In general, highly molecular material like high-damping rubber has large temperature dependence of mechanics characteristics. In order to consider the dependences of the damper on the temperature, the test sample was enclosed in a constant-temperature oven to keep the temperature constant. The experimental results were compared with the design formula of the damper proposed in this study. The design formula enables to express the damping force characteristics of this damper qualitatively and quantitatively. Moreover, the damping characteristics of the damper was examined with the Voigt model.
