This includes discussion of the wind field within the framework of stochastic processes as well as a probabilistic treatment of the combined effects of wind and ice loadings. The probabilistic modelling is reinforced by experimental data. Further it is outlined how the results of a dynamic load effect analysis can be applied in a consistent design procedure that accounts properly for the stochastic nature of the problem. The procedure is basically a Hasafer-Lind safety index approach working in a finite space of basic variables. The potential of this procedure is demonstrated by a numerical example which reveals the relative importance of some of the basic variables related to wind and ice loading.
