Vibration of Buildings Under Random Wind Loads
A method for analyzing the three-dimensional dynamic response of wind-excited buildings is presented. The wind and building models used in the analysis are similar to those used for analyzing along-wind response. The coupled along-wind, across-wind, and torsional vibrations are computed using random vibration techniques. The expected maximum translational responses and the torsional response are obtained. The objectives of this study were to identify which wind and structural properties influence the torsional response and to determine whether the predicted torsional responses are large enough to warrant extending the method to building-type structures. Only buildings with a rectangular cross-section and normally incident wind were considered. The buildings were modeled as either shear beams or as flexural beams. Galerkin's method was used to solve the coupled equations of motion. Studies were conducted to determine the influence of various geometric and mechanical properties of a building to its response. Several examples are presented to illustrate the significance of various parameters on the total response of buildings. The method may be formulated to analyze buildings subjected to earthquake-type loadings.
