Design Guide Cyclonic and Non-Cyclonic Regions

This Guide outlines the principles for determining design wind actions on steel sheds, garages and similar buildings for construction in Australia. It explains how structural designers should apply existing wind design criteria and concepts to the ultimate limit state design of steel sheds falling within a defined scope. It does not replace the Building Code of Australia (BCA), its referenced standards and other engineering texts but should be read in conjunction with them. This guide was compiled for distribution to building certifiers and shed suppliers.

Why it’s Important?

Regardless of their importance level or classification, buildings should not fail when subjected to the ultimate loading events for which they are certified to be designed.
Each building and its location are unique and the designer must ascertain the appropriate classification and importance level to determine the appropriate design actions on the structure.
Generic designs should take into account and clearly disclose in documentation and literature, the most adverse use for which a building may be sold or recommended or is reasonably likely to be used.

Application

This Guide applies to buildings with structural frames made predominantly from cold-formed steel and clad predominantly with steel wall and roof sheeting.

The following buildings are not covered:

Habitable buildings of any kind and any structures attached to them
Silos and similar produce stores where stored contents applies vertical or lateral wall loads
Buildings taller than 10 metres, longer than 100 metres or with span greater than 40 metres
Small garden type sheds, gazebos and summerhouses of less than 10 square metres floor area or less than two metres span or with eave height less than two metres
