The dynamic response of elevator compensating ropes in high-rise buildings

Research output: Contribution to Book/ReportConference Contribution

Abstract

High-rise buildings often suffer from severe vibrations induced by strong winds.
The low-frequency sway of the structure can excite elevator compensating ropes
installed in tall buildings. The specific danger arises when the building is excited
near its natural frequency. If simultaneously one of the resonance frequency of the compensating ropes coincides with the resonance frequency of the building large displacements of the rope occur. The paper focuses on the analysis of relevant models of the building – compensating rope system to predict its dynamic response. The analysis of the results of computer simulations offers an opportunity to discuss suitable control strategies to mitigate the effects of adverse dynamic response of the system.
