Abstract: Based on the wind pressure data obtained from the wind tunnel test of low-rise buildings conducted by the University of Western Ontario (UWO), the wind pressure characteristics on the roofs are discussed for different roof slopes, wind directions, building heights and terrains. For convenience, the taps at mid-span are taken as a reference. In consideration of different wind directions, the taps near the edge are also taken into account. In this paper, the statistical data of these taps are analyzed, including mean values, standard deviations, skewnesses, and kurtosises. In addiation, the variation of peak factors is studied based on Hermite polynomial for these taps. Results show that the wind pressure characteristics with small roof slopes are similar, and the wind pressures of the leeward side have weak non-Gaussianity. As the slope increases, the region with weak non-Gaussianity is located in the windward side; and a further increasing slope results in that the values of the skewness for taps at the windward side change from negative to positive. For oblique wind directions, the taps near the corner at the leading edge of the windward side have strong non-Gaussianity, which contributes to large peak factors. As the height increases, for the windward side, the peak factors of taps at the leading edge decrease, while those near the ridge line increase. The non-Gaussianity of the windward side is weaker under the open terrain compared with the counterpart under the suburban condition. Accordingly, the peak factors of taps at the windward side are smaller under the open terrain condition.
