Abstract
A first plate member and a second plate member are attached to a column member in such a manner as to be capable of undergoing relative displacement, and a viscoelastic material is disposed fixedly between the two plate members. As an alternative arrangement, a casing and a plate member inserted in the casing are attached to the column member in such a manner as to be capable of undergoing relative displacement, and a viscous material is filled in the casing. Drag occurs with respect to the plate member in conjunction with the vibration of the column member, thereby damping a structure.
