Internal pressure fluctuations in industrial buildings

Openings in a building envelope can generate large internal pressure in strong winds, and in combination with large external pressures can result in large net pressures across the envelope. Such a scenario, is a common cause of structural failure during windstorms. Internal pressures have been studied using analytical methods, wind tunnel and limited full-scale tests for over 40 years. This paper presents a review of past studies and describes a proposed study to determine internal pressure fluctuations in a range of industrial type buildings using full scale and model scale measurements, and analytical methods.
