Abstract
An elevator rope for a high-rise building is excited forcibly by the displacement of the building caused by wind forces. In this paper, an approximate solution to the forced vibration of a rope where both ends are moving is presented; based on the assumption that the rope tension and movement velocity are constant, and that the damping coefficient of the rope is small. Finite difference analyses of rope vibration are also performed to verify the validity of this approximate solution. The calculated results of the finite difference analyses are in fairly good agreement with that of the approximate solution.
