The present invention relates to a vibration control device having less damping and a lower unique vibration frequency and applied to an architectural structure, a civil engineering structure, a mechanical structure such as a wind power generator, a steel tower, an antenna tower, a main tower of a bridge or the like, a control tower, a tour tower, a material handling facility or the like in a place, such as a marine wind power generator, seriously swung by wave power or the like depending on the installation position when resonance including a beginning cycle ground motion due to an earthquake, strong wind of a typhoon, vortex vibration or the like occurs. The vibration control device is remarkably displaced in a horizontal direction and has less damping and a relatively low unique vibration frequency. When a vibration input such as an earthquake, a typhoon or the like is applied from the outside to a corresponding structure, a single system or multiple systems are installed between an upper part and a lower part as a hardpan of the seriously swung structure, thereby reducing relative displacement or absolute acceleration of the structure. |
