A damping intermediate pillar, which can exhibit a sufficient resistance against the horizontal force of a strong earthquake by reinforcing the joins between the damping intermediate pillar and the upper and lower beams, is disclosed. A damping intermediate pillar 14 , used for a building or a structure configured of pillars 1 and beams 3 , is divided into upper and lower damping intermediate pillar portions 14 a , 14 b of H shape steel, and includes a plurality of inner steel plates 7 b fixed on the damping intermediate pillar portion 14 b and a plurality of outer steel plates 7 a fixed on the other damping intermediate pillar portion 14 a. The inner and outer steel plates are arranged alternately in a single or a plurality of layers, between which a viscoelastic member 15 is held to make up a viscoelastic damper 17 . The coupling end surfaces of the intermediate pillar portions 14 a , 14 b directed vertically are fixed on the upper and lower floor beams 3 a , 3 b. Further, one or both sides of each of the damping intermediate pillar portions 14 a , 14 b (i.e. the coupling members 13 a , 13 b) and the upper and lower floor beams 3 a , 3 b are coupled to each other by knee braces 19.
