Theoretical solutions are reported for the nonlinear planar response of a flat-sag cable subjected to an axial sinusoidally time-varying axial load. This problem is solved by a Galerkin method. The resulting equations for time variables are integrated by using the Galerkin method. The effect of the initial conditions on nonlinear respnonse of a cable is examined at first. Nonlinear responses of the cable are presented for various sag-to-span ratios, ratios of wave speeds and dampings of the cable within unstable regions obtained by linear theory.
