Determining Cable Tensions of Cable Stayed Bridge Considering Viscous Damping

EasyChair Preprint no. 10262

10 pagesDate: May 25, 2023


Determining cable tension in long-span structures as cable-stayed bridges is necessary for inspection and structural health monitoring. The one of solutions for this problem is vibration measurement. However, it may not be accurate when parameters such as the sag, damping, and bending rigidity of cable are significant. On this page, the differential equation for the cable vibration is taken into account, including damping and bending rigidity in the cables. Then, assumptions of boundary conditions are simplified and expressions showing the relationship between frequency and tension are obtained. A practically applied procedure to determine cable tension through measured frequencies is proposed. The proposed procedure is verified by some cables of the Phu My bridge in Ho Chi Minh City.

Keyphrases: Cables, damping, Flexure, natural frequency, tension
