抑制できるようになった。<Effects of the Invention> According to the present invention, it is not necessary to increase the strength of the structure in order to support the structure for restraining, unlike the conventional vibration control structure using a water tank. Moreover, since the damping mechanism applies displacement resistance to the first member at a location longer than the length of the connection point and the upper floor portion where it is connected, the displacement resistance is relatively small due to the lever principle. It has become possible to apply a large amount of resistance with control force, simplify the configuration of the vibration damping mechanism, and effectively suppress vibrations of architectural structures at low cost.
