Review of internal pressures in buildings

Standards such as AS/NZS 1170.2 (2011) typically provide internal pressure design data for buildings with porous walls and/or with large openings in the envelope. However, these standards do not provide data in terms of the magnitude of porosity or the sizes of openings in the envelope and building volumes. Hence, there is a need for analysing the effects of the size of volume and the envelope porosity on the internal pressures generated. This paper presents a review of past studies, and proposes a study to determine internal pressures in industrial type buildings using full scale and model scale measurements, and analytical methods.
