VIBRATION CONTROL MEMBER FORMED INTEGRALLY WITH ELASTO-PLASTIC AND VISCOELASTIC DAMPER

WIPO Patent Application WO/2000/071840

A1

A vibration control member formed integrally with an elasto-plastic and viscoelastic damper for bracing materials and studs used mainly as earthquake and wind resistant members of a structural body, low in cost, and high in reducing effect of vibration by large, medium, and small earthquakes and strong wind, wherein damping material (3) is filled around a steel center axial force member (1), the outer side of the damping material (3) is covered by a first steel buckling prevention member (2a), damping material (3) is filled to the outside of the first steel buckling prevention member (2a), the outside of the damping material (3) is covered by a second steel buckling member (2b), one end of the steel buckling prevention member (2a) is fixed to one end of the steel center axial force member (1), one end of the second steel buckling prevention member (2b) is fixed to the other end of the steel center axial force member (1), and the first steel buckling prevention member (2a) is in contact viscoelastically with the second steel buckling prevention member (2b) through the damping material (3).
