The design of a member for combined actions is divided into seven design checks. The user can select to check the section capacity and/or the member capacity about either the major and/or minor axes as well as in biaxial bending.

When using NZS3404, the combined actions checks are only performed if the member has a significant axial force as defined in the design code.

No design properties are required when checking or designing members for combined actions using AS4100 or NZS3404.
