Abstract

According to the cable vibration frequency equation with elastic boundary conditions, sensitivity of cable tension to the calculation model parameters are derived taking into account the bending stiffness. The cable tension uncertainty evaluation equations of cable tension to each parameter are obtained. The correctness of this cable tension uncertainty evaluation method is verified by check experiment of cable tension test on a tied-arch bridge and a cable-stayed bridge. Special software is developed for calculating the cable tension and the cable tension uncertainty.
