Abstract
Since current design practice often leads to slender and flexible buildings, the dynamic effects of the wind are of increasing importance. The purpose of this study was to develop a method for analyzing the three-dimensional dynamic response of buildings subjected to random wind loads. The analysis procedure utilizes random vibration techniques and parallels the gust factor methods currently used in engineering practice. Expressions for the spectra of the along-wind forces, of the across-wind forces induced by vortex shedding and of the total dynamic torque were developed for normally incident wind. Rectangular buildings were modeled as either three-dimensional continuous shear beams or flexural beams. The results of the analysis are the expected maximum translation and acceleration of any point on the structure. Several examples are presented to illustrate the significance of various parameters on the total response of buildings. The method is quite general and may be extended to include the analysis of buildings subjected to earthquake-type loadings.
