This study has been performed to evaluate the wind load for design of a suspended bridge. A meteorological station was installed at each pylon area and the data was collected. Additionally, wind data from other weather stations located nearby the site was also considered. The basis wind speed has been estimated by extreme wind analysis using historical extreme wind records, which are measured nearby two representative meteorological stations. In order to estimate the basis wind speed for 100 years, the Gumbel’s extreme statistical analysis is performed. The turbulence properties of fluctuating wind speeds such as turbulence intensity, spectrum and coherence also have been verified based on the field measurement data. The evaluated turbulence intensities are compared with the engineering model. The turbulence spectra were calculated using the high wind speed recordings and compared to the Kaimal Spectrum. |
