Abstract: The world's population is rapidly growing and as a result, there is a scarcity of available land for development. In order to accommodate more people in a compact space, there is now a need for vertical development and architecture, which involves constructing structures that are taller and slenderer. Taller structures create a challenge since they must be more stable and resistant to seismic and wind effects, which are more dominant on them. A passive control device system called Clutching Inerter Damper (C.I.D.) is a unique device that can reduce these vibrations and are used as a vibration-controlling tool to safeguard tall buildings during earthquakes. The tool can control motion since it is made up of a clutch mechanism and a rotary inerter. This paper offers a thorough analysis of this unique device's operation and its operating principles and provides a full assessment of the prior research done on it. The study concludes with a comparison of the responses obtained using this device and those obtained using prior studies when applied to a multi-degree of freedom (MDOF) system under seismic excitation. Response reduction in terms of % has been established to provide the effectiveness of the C.I.D. According to the study's findings, the C.I.D. system improves the seismic stability of the building and exhibits special benefits in moderating the resonant response because of the C.I.D.'s mass magnification effect generated by inertance.

Keywords: Clutching inerter damper, vibration control, seismic, resonant response, tall buildings, multi-degree of freedom.
