Ultimate limit state (strength) (Columns: AS 4100)

The checks relate to doubly symmetric prismatic sections (that is rolled and welded I- and H-sections), to singly symmetric sections i.e. Channel sections, and to doubly symmetric hollow sections i.e. CHS, RHS and SHS. Other section types are not currently covered. The strength checks relate to a particular point on the member and are carried out at regular intervals along the member and at 'points of interest'.

Note: Hollow sections: The checks for CHS, RHS and SHS relate to “hot-finished hollow sections” only - “cold-formed hollow sections” are not included in this release.
