The characteristics and structures of the pressure fields on the roof and wall edges of a low-rise building with a 4: 12-pitched roof have been investigated by using a data-base, which was constructed at BLWTL, The University of Western Ontario. Detailed analyses of the data are made for one specific wind direction, i.e. the worst wind direction, for each surface of the building. This paper presents the results on the statistical properties of the fluctuating pressures; that is, the probability density function, level-crossing rate, peak factor etc. The time-space correlation of the pressure fluctuations is discussed based on the spectral analysis. Quantitative descriptions for various aerodynamic parameters are provided.
