Abstract EN
This paper analyzes the influences of important structural design parameters on the wind-induced response of cross-rope suspension tower-line.
A finite element model of cross-rope suspension tower-line system is established, and the dynamic time-history analysis with harmonic wave superposition method is conducted.
The two important structural design parameters such as initial guy pretension and sag-span ratio of suspension-rope are studied, as well as their influences on the three wind-induced vibration responses such as tensile force on guys, the reaction force on mast supports, and the along-wind displacement of the mast top; the results show that the value of sag-span ratio of suspension-rope should not be less than 1/9 and the value of guy pretension should be less than 30% of its design bearing capacity.
On this occasion, the tension in guys and compression in masts would be maintained in smaller values, which can lead to a much more reasonable structure.
