In this study, from the viewpoint of anti-earthquake design, the isolation performance of various types of base isolated structures subjected to long-period earthquake motions is evaluated. Using four types of dampers such as oil damper, nonlinear viscous damper and controllable friction damper, the maximum acceleration responses and maximum displacement responses of base isolated structures subjected to not only actual short-period earthquakes like El Centro and JMA Kobe earthquake motions but also artificial long-period earthquake motions like Nagoya-Sarmomaru earthquake motion are compared. From this comparison, it is clear that the controllable friction damper can suppress relatively the maximum responses against both earthquake motions.
