Abstract A retractable roof stadium rigid model was made with a scale of 1:300, and wind tunnel tests were carried out to measure the wind pressures on the roof in category type B. The stochastic characteristics of the wind pressures were particularly studied, using probability plot correlation coefficient method to find out the optimum marginal probability distributions which were Gamma distribution and Normal distribution to fit the distribution of wind pressures coefficients on the roof, a standard translation processes approach was introduced to estimated the peak factors. According to our calculations,(1) The non-Gaussian characteristics of wind pressures on the retractable stadium roof can be taken account into. This method can be used to estimate the extreme pressure coefficients more safely ;(2) On the fixed roof ,when the retractable roof is opened, the total extreme pressure coefficients are lightly larger, most taps located on the top of the fixed roof; but on the retractable roof ,the extreme pressure coefficients are smaller.
