Abstract

The nonlinear random oscillations of a cable induced by a turbulent wind are investigated proponing a discrete model, with quadratic-cubic nonlinearities and parametric excitation terms arising from geometric and aerodynamic effects. The formulation is independent of the order of discretization adopted for representing the cable motion and the turbulence field, as well as the order of the nonlinear terms retained in the expression of the aerodynamic force. A parametric analysis on a realistic model of suspended cable highlights the importance of the different classes of nonlinear terms enclosed in the model.
