To provide an aseismic structure and an aseismic damper, which prevent damage to a column capital part by preventing an end of a steel material for a damper arm part from being connected to the column capital.
The aseismic structure is constituted by supporting an upper mounted structure 1 with a beam 5 by a column 2 fitted with the aseismic damper; an upper end 4 of a damper part 3, which is constituted by making a plurality of slender steel plates and a plurality of rectangular steel plates alternately face one another and by sandwiching a viscoelastic material layer between the respective steel plates, is mounted on the beam 5 of the structure 1; and a lower end 6 is mounted on the intermediate part of the column 2. This enables effective utilization of a space without closing an interlayer opening part of the structure while preventing the damage to the capital part, and makes an effective seismic response control function exerted even on bending deformation of the structure.
