Dynamic Response of High-Rise Building Subject to Wind Excitation
The dynamic responses of tall buildings subject to wind loadings are investigated. A finite element model for a three-dimensional, multi-story building is used to consider the contributions of every member, including beams, columns, panels, and shear walls. The fundamental meteorological behavior applicable to response analysis of tall buildings is described. Aerodynamic forces on a tall building are calculated using a deterministic pseudo-turbulent approach. These aerodynamic forces are distributed along the height of the building. The equivalent concentrated aerodynamic loads, acting at each floor level, are calculated using the principle of virtual displacements. Two computer programs are developed to calculate the displacements at each floor level. The first program utilizes an iterative procedure for response calculation; the second takes advantage of the linearization process and calculates responses for the linear problem. A fifteen story building is modeled for application and results are presented in the form of response spectra for different gust frequencies.
