PROBLEM TO BE SOLVED: To provide a triple pipe damping brace excellent in energy absorption capacity without lowering proof stress by the whole buckling and local buckling of an axial pipe resulting from earthquake. SOLUTION: In the triple pipe damping brace coaxially arranging the axial pipe 12 coaxially connecting a general structure steel pipe 14 to a low yield point steel pipe 16 and stiffening pipes (26 and 28) are respectively coaxially arranged to the inside and the outside of the axial pipe 12, a comblike finger section 40 is extended and formed in the end edge of the general structure steel pipe 14 of the axial pipe 12, and the triple pipe damping brace is so constituted that a slit groove 46 in which the finger section 40 is inserted in the outer circumferential surface of the inside stiffening pipe 28, is formed.
