Abstract Simultaneous occurrence of rain and wind can lead to vibrations with large amplitudes of inclined cables and hangers of arch bridges. These motion‐induced vibrations are usually described with models based on the strip theory, or on the cable theory which is the best developed model [1]. The own solution concept derives complete nonlinear cable equations being mechanical equal to those known in literature but with a significant more simple structure by using longitudinal Green's strains and non‐physical cable forces. The nonlinear effects of wind and rain forces are included. As an example of application a cable of the Erasmus bridge in Rotterdam (NL) will be analyzed. The own results are compared with the vibration amplitudes in the literature and with observations. (© 2009 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
