STUDY ON STRONG WIND POWER SPECTRUM FOR COASTAL AREA OF EAST CHINA

The purpose of this paper is to formulate the wind speed power spectrum using the time history data of strong wind speed in east China coastal 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 Jiangsu Province 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 simplified wind speed power spectral formula for wind-resistant structural design for coastal area of east China is presented.
