摘要： PROBLEM TO BE SOLVED: To improve the vibration control capacity at a low cost, by assembling a member absorbing the displacement energy at the time when a plurality of beams are relatively displaced in the horizontal direction, between the beams positioned at the upper and lower sides in the building frame of a structure and forming the member absorbing energy by using a vertically extending hollow cylindrical body. SOLUTION: In a building frame 1 chiefly constituted of columns 2 and beams 3, a damper 5 is erected as a stud forming a vibration-resistant element at the central part of vertically arranged beams 3, 3. The damper 5 is connected to respective beams 3, 3 and provided with an energy-absorbing member (cylindrical body) 8 between vertically extending brackets 6, 7. The energy-absorbing member 8 is formed of an extremely mild steel pipe with a square section having a lower yield strength than the column 2, the beam 3, and the brackets 6, 7 and the upper and lower ends thereof are connected to the brackets 6, 7 respectively. In this way, when two-directional horizontal external forces resulting from an earthquake, strong wind, etc., act on the building frame 1, the horizontal relative displacement energy of the upper and lower beams 3, 3 can be absorbed.
