Abstract

This paper presents and validates an original and practical finite difference model to investigate the thermoelastic response of suspended cables. The mathematical formulations are provided for various loading cases. The model includes the effects of cable extensibility and large sag, as well as variability of temperature gradients and thermal properties of the cable along its arc-length. The formulations are programmed and used to study suspended cables subjected to different thermomechanical loads. The results are validated against analytical or finite element solutions, and the proposed model is shown accurate and efficient in assessing the thermoelastic response of suspended cables.
