Abstract:	Roof curvature and Reynolds number effect significantly define the characteristics of wind pressures on domed roof structures. Once the flow separates from the roof surface, apparent changes in aerodynamic coefficients or non-Gaussian wind-induced pressure spectra are expected. This paper investigated the non-Gaussian peak factors of wind pressure coefficients on domed roofs under a simulated suburban boundary layer flow. By estimating the higher statistic moments, skewness and kurtosis coefficients, and adopting the moment-based Hermite polynomial translation techniques, including the softening and hardening processes, comparisons were made based on the empirical and simulated results. The fairly good estimation results by translation process were demonstrated and the influence on the estimation of wind pressure extremes was discussed in a practical viewpoint.
