Title: Vibration-damping structural member
Inventor: ISHIMARU TATSUJI
IPC: F16F15/04
Filed: 2002-06-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vibration-damping structural member which suppresses vibrations of a structure without additional provision of a vibration control device or the like.  <P>SOLUTION: When columns 14 and beams 16 are horizontally deformed due to application of an external force of an earthquake or the like, relative displacement is generated at connecting pins 30, 34 arranged on diagonals in a frame portion. The relative displacement is amplified by first and second arm members 28, 32 forming a damping mechanism 13, and therefore an oil damper 44 connected to a connecting shaft 36 is largely deformed, to thereby restrict relative movement of the connecting shaft 36 and absorb vibrations of the structural member. More specifically, vibrations caused by the relative displacement between the structural members such as the columns 14 and beams 16 are not absorbed but vibrations caused by the displacement of the structural members per se are absorbed, and therefore vibrations of the structure caused by an earthquake or wind can be effectively damped, to thereby dispense with securement of a space for additional provision of the vibration control device in the structure.  <P>COPYRIGHT: (C)2004,JPO
