The characteristics and structures of the pressure fields on the leading edge and corner regions 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. An empirical formula for estimating the minimum pressure coefficient is provided based on a peak factor approach. For constructing the formula, the quasi- steady theory is applied to the evaluation of the rms pressure coefficients The application of this formula is examined by comparing the predicted results with the experimental ones. The relation between the spatial and time averages is discussed, regarding their effects on the peak pressure coefficients. Furthermore, a discussion is made of the performance of the AIJ Recommendations for Loads on Buildings (1993) for estimating the design wind loads on cladding of low-rise buildings.
