Abstract

Abstract

Based on basic theory of pulsating wind and Davenport's power spectrum of wind pressure,a calculating method of wind-excited response of tall building structures in frequency domain is presented,the random vibrations analysis of tall building structures by power spectral density of the wind pressure is also carried out.The natural frequency,the mode and change in stresses after applying the wind pressure spectra to the structure are obtained by power spectral density based on ANSYS.The results indicate that analysis and treatment methods presented here are reasonable and feasible.
- tall building structure,
- wind load,
- power spectral density of wind pressure,
- ANSYS
