Abstract

The Purpose of this paper is to formulate the wind speed power spectrum by time history data of strong wind speed in Taiwan area. By utilizing random vibration theory and statistical regression analysis, a systematic analysis and discussions of along wind turbulence effects for wind speed power spectrum is performed. This study includes the time history data collection of along wind speed for typhoon in Taiwan and the regression analysis of wind speed spectral formulas. The strong wind speed data was first transformed from time domain to frequency domain. Then, the statistical analysis methods were applied for spectrum formulation and regression analysis. At the end of this study, a suitable along wind speed power spectral formula for future wind-resistant struc tural design for Taiwan area is presented.
