To provide a seismic strengthening structure which can improve energy absorption performance and repeating performance.SOLUTION: A seismic strengthening structure includes an outer steel pipe 2 whose one side end 2a is connected to one part 53a to be connected of a structure 50 to be strengthened, a shaft material 3 whose one side is inserted into the pipe of the outer steel pipe 2, and in which the other side end 3b projecting to the other side from the outer steel pipe 2 is connected to the other part 53b to be connected of the structure 50 to be strengthened, and intermediate plate materials 4 arranged on both sides in a thickness direction Z of the shaft material 3 in the outer steel pipe 2, wherein the other side ends of the intermediate plate materials 4 and the outer steel pipe 2 are joined to each other, and the one side ends of the intermediate plate materials 4 and the shaft material 3 are joined to each other. In a predetermined range between the joint part of the other sides of the intermediate plate materials 4 and the outer steel pipe 2, and the joint part of the one sides of the intermediate plate materials 4 and the shaft material 3, a narrow part 3n narrower than the width sizes of the one side end 3a and the other side end 3b of the shaft material 3 is provided on the shaft material 3.SELECTED DRAWING: Figure 3 【課題】エネルギー吸収性能と繰り返し性能を向上させることができる耐震補強構造体を提供する。【解決手段】一方側端部２ａが補強対象構造物５０の一方の連結対象部５３ａに連結される外鋼管２と、一方側が外鋼管２の管内に挿入され、外鋼管２から他方側に突出した他方側端部３ｂが補強対象構造物５０の他方の連結対象部５３ｂに連結される軸材３と、外鋼管２の管内で軸材３の厚さ方向Ｚの両側にそれぞれ配設された中板材４とを備え、それぞれの中板材４と外鋼管２の他方側端部どうしを接合し、それぞれの中板材４と軸材３の一方側端部どうしを接合した構成にする。さらに、中板材４と外鋼管２と他方側の接合部と、中板材４と軸材３との一方側の接合部との間の所定範囲において、軸材３に、軸材３の一方側端部３ａおよび他方側端部３ｂの幅寸法よりも幅を狭めた幅狭部３ｎを設けた構造にする。【選択図】図３
