Abstract: The effect of cable loosening on the nonlinear parametric vibrations of inclined cables is discussed in this aper. In order to calculate loosening for inclined cables without a small-sag limitation, it is necessary to first derive equations of motion for an inclined cable. Using these equations and the finite difference method, the effect of cable loosening on the nonlinear parametric responses of inclined cables under periodic support excitation is evaluated. A new technique that takes into account flexural rigidity and damping is proposed as a solution to solve the problem of divergence. The regions that generate compressive forces in inclined cables are also shown.
