The Cyclone Testing Station operates a 2.5m x 2.0m x 22m long Boundary Layer Wind Tunnel to conduct research in the field of wind effects on building structures. These research outcomes find many practical applications by being incorporated in wind loading standards such as AS/NZS 1170.2 AS/NZS 4650, and building codes of practice. Spatial and temporal characteristics of wind pressures acting on various types of structures (such as canopy roofs, houses, industrial sheds and stadiums) and their response to these fluctuating pressures are being studied. Variations in internal pressure with varying envelope porosity and its interaction with the external pressure distributions are also analysed in determining the net wind loads on cladding and the primary structure. Other research areas of interest include the use of pressure distribution for estimating the natural ventilation potential in houses, and the study of wind flow patterns over complex topographical features which may be used in determining a site's wind energy potential.
