摘要
En 中文
A simple, nine degrees-of-freedom model has been presented to describe vibrations of an inclined cable by using a generalised finite element approach. All three translations of a vibrating cable and of the support points have been included in the model for its use over a wide range of cable supported structures. The model has been validated for free as well as forced responses of inclined cables by comparing the results with analytical solutions. Some illustrative examples are considered to demonstrate the applicability of the model for analysing vibrating cables and guyed towers subjected to gusty wind. It has been demonstrated that the model can be utilised to expeditiously predict the dynamic response of cable supported structures. (C) 2000 Elsevier Science Ltd. All rights reserved.
