| Abstract |
The mechanism of unsteady aerodynamic force on structures related to gusty winds has been investigated. However, there is very little observation of gusty winds which damage structures and so their ac...tual features haven't been clear yet. In this paper, we analyzed the statistical information of gusty winds to estimate unsteady wind pressures acting on actual structures. We matched the selected gusty winds with experimental results and calculated wind speeds equivalent to generate estimated unsteady wind pressures on actual structures. Then the equivalent wind speeds were compared with observed values. Our results showed that the estimated wind pressures were approximated with probability density function and the equivalent wind speeds generating wind pressures associated with return period of 10 years are stronger than observed wind speeds.show more
