The forced vibration of a suspension cable system under the external excitation of the point, on which the concentrated load acts, was investigated for suspension cable with both ends built-in and the concentrated load acting on. The analytic solution to primary resonance bifurcation was obtained by adopting the multiple- scale method.Through computing instances, the position and graph of bifurcation of primary resonance for modes of all ranks were obtained.
