Understanding optimal damper characteristics is useful in the seismic design of vibration control structures. Additionally, it is known that soil–structure interaction (SSI) significantly affects structures’ earthquake responses. The impact of SSI on seismic response is therefore an important issue in the seismic design of structures. Despite the importance of these factors, few previous studies have investigated the optimal damper characteristics of vibration control systems while considering SSI effects. In the present study, to determine the optimal damper characteristics of passive systems considering SSI, a series of shaking table tests were conducted using a vibration control structure model with a sway–rocking mechanism under the superstructure. To investigate the optimal damper characteristics, which are the values that effectively minimize the peak response, a simple friction damper device that allows the slip force to be easily set to various magnitudes using rubber bands and stainless plates was used in the shaking tests. The test results yielded the optimal slip force characteristics of the friction damper, which were found to vary according to the sway–rocking conditions and the level of input motion.
