STRUCTURE FOR SEISMIC ISOLATION, STEEL SUPPORT STRUCTURE, AND METHOD FOR SEISMIC ISOLATION OF EXISTING STEEL SUPPORT STRUCTURES.

摘要

The structure for seismic isolation 10 is provided on a structure face 17 comprising a pair of columns 5, 5 disposed on the right and left with a space therebetween in the horizontal direction, and a pair of beams 7A, 7B disposed on the top and bottom with a space therebetween in the vertical direction. The seismic isolation structure is characterized by comprising: a seismic isolating device 11 that is provided in the middle of each of the columns 5, 5 by being displaced toward the beam 7A side; and a rigid horizontal loading element that is provided between the beam 7B and the site where the seismic isolating device 11 is provided, and that comprises vertical braces 15L, 15R, and a connecting beam 13 connecting the pair of columns 5, 5.
