| [en] In the civil engineering field, the analysis of structures subjected to wind loading
is generally based on several hypotheses. Their justification is often fuzzy and they are usually postulated in order to apply simplified mathematics. These hypotheses allow the resolution to be run in a gaussian context. This work aims at presenting and applying an analysis which allows accounting for the usually neglected terms of the loading. When studying multi degree of freedom structures, other simplifications concerning the coupling effects between modes are generally formulated. These conditions are also approached and several solutions to take them (eventually partially) into account are proposed. From the simplest analysis of a single degree of freedom system subjected to a simple aerodynamic loading, this work presents more and more complex structures. The last step is to present to developments necessary to analyse a real structure. The developments will allow to analyse a linear 3-D structure subjected to a 3-D aerodynamic field whose non linear characteristics are taken into account. These non linear effects can come from the quadratic terms in the expression of the turbulence and from the non linearity of the aerodynamic coefficients in terms of the wind angle of attack. | |
