While Division 1 is predicated on normal stress theory, Division 2 is predicated on maximum distortion energy (Von Mises). The codes mentioned under Section VIII for both divisions also having appendices. These appendices are alternative or supplementary rules that function guidelines since they’re less frequently employed than the most body codes. However, the appendices themselves contain both mandatory and non-mandatory sections regarding the design of the sections. The mandatory appendices are as important as the code itself and provide alternative rules to the main codes included in the body.

Currently, the 2015 edition is in practice, while the 2017 edition will be made available to the public by July 2017.
