Abstract
Nonlinear dynamic response of a suspended small-sag cable driven by harmonic axial load and harmonic transverse load is presented. The basic equation of motion is solved by a Galerkin method for space co-ordinate and the averaging method for time co-ordinate. The single-degree-of-freedom approach is employed in this paper. The accuracy of the present solution is discussed at first. Then, nonlinear dynamic responses of a suspended cable are shown for various sag-to-span ratios, damping ratios and amplitudes of harmonic load.
