<p><P>PROBLEM TO BE SOLVED: To provide an effective and appropriate vibration control structure capable of efficiently operating respective dampers when the plurality of dampers are installed over two stages within one structure plane. <P>SOLUTION: A brace 3 in a chevron shape or an inverted chevron shape is provided within the structure plane, and a first damper is connected to a joint member 4 in such a state that its axis passes through a peak O of the brace. A second damper is pin-joined to the joint member so as to be relatively rotated within a vertical plane at a position of the peak of the brace, and is supported and installed to the structure plane so as to be slid in an in-plane horizontal direction and not to be displaced in a vertical direction. The first damper is turned to an oil damper 7a, the second damper is turned to an inertia mass damper 7b, and an additional spring 8 is pin-connected thereto in series so as to be relatively rotated within the vertical plane. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
