Abstract: A plurality of column members 6a, 6b of a rack are joined with an earthquake-damping joint 21. The earthquake-damping joint 24 comprises a deformation portion 24, which is narrower so as to gain increased plastic formability, and a pair of fixing portions 26, which are strengthened with increased thickness, to join an upper joint section 20a and a lower joint section 20b with a plurality of bolts 28 or the like. Said deformation portion 24 is deformed by the horizontal stress applied in the direction perpendicular to the longitudinal direction of the rack and the upper column member 6a moves upwardly, absorbing the vibration energy. Said fixing portions 26 are strengthened by increased thickness so that the bolts 28 do not yield to the shock.
