# AS 4100 (2020)

This Standard provides designers of steel structures with specifications for steel structural members used for load-carrying purposes in buildings and other structures.

Note: Checks are performed for the following symmetric cross sections: I-beams, Channels, Tee, Circular and Rectangular tubes, Circular and Rectangular bars.

To add the Standard execute
