An outline is given of the manner in which expressions for the buffeting forces of the wind, together with those for the self-excited aerodynamic forces due to resulting bridge motion, may be used to predict the random response of a long-span bridge to the action of the natural wind. The problem is examined in terms of the individual responses of the several modes of the structure as they are randomly excited, both in space and in time, by wind gusts. The bridge deck modes in question are each considered to have vertical, torsional and lateral sway components. Recent formulations for wind horizontal and vertical gust spectra are employed. More complete literature references are cited for the details of the methodology used. /Author/
