Abstract	We investigate the nonlinear random vibration of the cables with small sag and excited by colored noise being filtered Gaussian white noise uniformly distributed on the cable. The nonlinear multi-degree-of-freedom systems are formulated based on the revised equation of motion of the geometrically nonlinear cable with Galerkin method. The nonlinear MDOF systems governing the motion of the cable at a given point are formulated and analyzed when the excitation is the filtered Gaussian white noise governed by linear second-order stochastic differential equation. Numerical results obtained with the state-space-split-EPC method, Monte Carlo simulation, and equivalent linearization method are given and compared. The computational efficiency and numerical accuracy of the three methods are also compared.
