Abstract: A damping device for structure includes a base frame installed on a target place, an air floating mass disposed on the base frame to blow off air, a TMD mass disposed above the base frame to float with an air pressure, one pair of guiderail units disposed on X-direction both sides of the base frame along the X direction respectively, slider units disposed to be slidable in the X direction relative to the guiderail units, coupled to each X-direction side face of the TMD mass and each including a slider moving up/down mechanism part which moves down a slider when the TMD mass floats, an oil damper attached to the base frame to exert an attenuation action on the TMD mass and a coil spring attached to the base frame to exert a restoration action on the TMD mass.
