Patent ID: 8677699

Claim:
A vibration control device for a beam-and-column frame being constituted of beams and columns, the device comprising: a parallel member being disposed inside the frame of said beam-and-column frame, being disposed between a first member and a second member in a manner of separating away from said first member and said second member, the first member and second member facing each other, the parallel member and the second member having opposite side ends, and the parallel member being disposed to parallelly face with respect to said first member; a rotary supporting member being disposed in a space between said first member and said second member, thereby supporting a central section of said first member and that of said parallel member rotatably relatively; a first brace connecting one of the opposite-end sides of said parallel member with one of the opposite-end sides of said second member or a neighborhood of one of the opposite ends of said second member; a second brace connecting the other one of the opposite-end sides of said parallel member with the other one of the opposite-end sides of said second member or a neighborhood of the other one of the opposite ends of said second member so as to intersect with said first brace when being viewed from a front of said beam-and-column frame, and being disposed so that a position at which said second brace intersects with said first brace is positioned more adjacent to a side of said first member than where an intermediate position between said first member and said second member is present; and damper members being disposed respectively so as to be interposed between said parallel member and said first member, connecting said parallel member with said first member, and being disposed to make a pair at least on both sides each of which is separated away from said rotary supporting member to interpose said rotary supporting member therebetween.
