ABSTRACT:
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 pillar14, used for a building or a structure configured of pillars1and beams3, is divided into upper and lower damping intermediate pillar portions14a, 14bof H shape steel, and includes a plurality of inner steel plates7bfixed on the damping intermediate pillar portion14band a plurality of outer steel plates7afixed on the other damping intermediate pillar portion14a. The inner and outer steel plates are arranged alternately in a single or a plurality of layers, between which a viscoelastic member15is held to make up a viscoelastic damper17. The coupling end surfaces of the intermediate pillar portions14a, 14bdirected vertically are fixed on the upper and lower floor beams3a, 3b. Further, one or both sides of each of the damping intermediate pillar portions14a, 14b(i.e. the coupling members13a, 13b) and the upper and lower floor beams3a, 3bare coupled to each other by knee braces19.
