Abstract
The lateral vibration of elevator ropes for high-rise building, which is excited forcibly by the displacements of the building induced by wind forces, is numerically analyzed. Finite difference analyses of the rope vibration with/without vibration suppressor are performed. The advantage of using the vibration suppressors for reducing the rope lateral vibration is demonstrated through the numerical calculation : As the number of the vibration suppressor is made greater, the maximum rope deflection becomes smaller. The resonant position of the rope with vibration suppressor is greatly depends on the distance between the rope and the vibration suppressor.
