Rocking Center Designated (RCD) Mechanism is proposed as a tool to control the vibration modes of structures. An ideal RCD mechanism is simply a rigid body guided on a sphere surface, and the rocking center of the rigid body is decided and designated by the curvature of the sphere surface. And the RCD mechanism can also be realized by replacing vertical columns in soft story structure by diagonal columns that pointed to the rocking center. If the RCD mechanism is incorporated into a structure, the vibration modes of the structure can be designated and the input of motions at a specific position can be controlled. In this paper, RCD mechanism and its effectiveness in structure control are explained. Structure using the concept of RCD mechanism is expected to be a new strategy for eliminating damage of civil structures during intense earthquakes.
