GUIDANCE

Omit PS, ELs or ELw column header rows when the section does not include planes of symmetry, stiffeners or welds data respectively. This program is typically suitable for sections composed of slender or compact rectangular elements. BAS007 is suitable for any compact section which can be idealised as having straight edges.
