✦ Synopsis

Al~tract--ln this paper, based on the present author's earlier study about the random process of wind, the elastic engineering structure response to wind load is analysed by means of the random vibration and finite element method. From the most general model the formulae for calculating the response power spectrum and mean square value of displacement and stress of structure are derived, with which both the static and dynamic response of structures can be obtained simultaneously. Finally, a large antenna structure in engineering is calculated as an illustration. Its response to Davenport's wind load spectrum is given.
