アブストラクト In order to study effectiveness of dampers in the super-tall buildings subjected to long-period and long-duration earthquake, four types of full-scale dampers typically used in Japan are examined by the long-duration harmonic loading tests. The test specimens are the so-called oil damper, viscous damper, viscoelastic damper, and steel damper, respectively. Different behavior and variations in their dynamic properties are observed, and they are summarized by referring to distinct materials and mechanisms of the dampers. The viscous and viscoelastic dampers show relatively large variations in the dynamic properties, and simplified evaluation rules to predict the peak cyclic force variations for the dampers are proposed.
