This study was made when the first author stayed at BLWTL, The University of Western Ontario, as a research investigator supported by the Ministry of Education, Science, Sports and Culture, Japan, during the period from March to June 1996. The wind tunnel experiment was financially supported by the Canadian Wood Council and the American Forest and Paper Association.

N2 - Wind-induced pressures were measured simultaneously at many points on wind tunnel models, typical of simple low-rise buildings, in two kinds of turbulent boundary layers, which simulated the natural winds over typical open-country and suburban terrains. Special attention is paid to the spatial and temporal characteristics of the pressures near the roof and wall edges. This paper presents the results for (i) variation of the instantaneous pressure distribution with time, during a time period which captures the occurrence of the maximum observed suction; (ii) statistical characteristics of the pressure fluctuations; and (iii) effects of the time and spatial averaging on the magnitude of the effective minimum pressures. Based on the results, an empirical formula for estimating the minimum pressure coefficients, using a peak factor approach, has been developed. Quasi-steady theory is applied to evaluate the RMS pressure coefficients. The relation between the spatial and time averages is also discussed.
