Why are wind ratings important?
ULS - To satisfy the ultimate limit state, the structure must not collapse when subjected to the peak design load for which it was designed.
To satisfy the serviceability limit state criteria, a structure must remain functional for its intended use subject to routine /everyday loading, and as such the structure must not cause occupant discomfort under routine conditions.
Every site for every building in Australia should be assessed for wind load requirements and should be stated on the approved build plans as a 'N 1-6' or 'C 1-4' rating
Understanding wind loads & their potential to impact on a building will help us design & specify appropriate products to ultimately
There are two Australian Standards that are used to determine wind loads for a building: AS 1170.2 Structural Design Actions and AS 4055 Wind Loads for Housing. As its name suggests AS 4055 may only be used to determine wind loads for “housing” which has a specific meaning under the code – only building classes 1 & 10 (a house and a garage/carport) within specific geometric limits may use AS 4055: all other building classes 2 through 9 must use AS 1170.2.
