PROBLEM TO BE SOLVED: To provide an aseismic control structure efficiently constructed by equalizing the amplification magnification of positive force application and negative force application of an aseismic control device, and suppressing the occurrence of noise/vibration/dust. SOLUTION: The aseismic control structure 1 has an aseismic control device 6 composed of an outer frame 8 of the same shape as a frame 5 comprising columns 3 and beams 4 of a building 2, and a variable brace mechanism 9 formed by connecting the tip part of a damper 25 extended from one side of the other diagonal part of the outer frame 8, to the tip parts of a first brace 21 and a second brace 22 with the rear ends rotatably installed at one diagonal part of the outer frame 8. The seismic control devices 6 are installed in lateral symmetry at the frame 5 comprising the columns and beams of each floor of the building 2. COPYRIGHT: (C)2009,JPO&INPIT
