Wind Speed Time History and Wind Load Simulation Using Harmonic Analysis Method

To more accurately evaluate Davenport wind speed, we employ harmonic analysis method to analyze wind speed time history and wind load conditions. The harmonic analysis technique decomposes signals into multiple frequency components, enabling better understanding of signal characteristics and behavior. For Davenport wind speed signals, this analysis provides detailed information about wind speed variations and wind load conditions, offering deeper insights into their impact on structures such as buildings. The implementation typically involves Fast Fourier Transform (FFT) algorithms to convert time-domain wind data into frequency-domain components, followed by inverse transformation to reconstruct the wind field. Key functions include power spectral density calculation and phase angle randomization for realistic simulation. Therefore, harmonic analysis serves as a powerful analytical tool that helps improve assessment and prediction of Davenport wind speed effects on engineering structures.
