With HSS design, when selecting members steel grade, the G450 registers in the template, but G350 reverts to G250? This results in reduced design capacities based on G250 Steel, which also has knock on effects for weld and bolt attachments. This is when using the ASW.asc sections. Have been advised to use International steel grades but this raises other issues with compatibility of materials and ductility design issues. Has anyone else had this problem? Has anyone else found a work around? we've tried entering new a grade into the library, but it keeps defaulting to 250. HELP!?
