Gross properties are based on the full section away from flange slots. 2. Net area is based on the section through the flange slots. 3. Weight is nominal weight of the gross section, not reduced for flange slots. 4. Effective properties are calculated in accordance with the 2007 NASPEC with 2010 Supplement (AISI S100-07/S2-10). For effective flange widths, the compression flange (before local buckling) is taken as the portion of the flange between the web and the slot (the slot and any steel beyond the slot is considered absent). The tension flange is taken as the net flange at the slots. 5. Cold-work of forming has not been considered for effective properties. 6. Web width-to-thickness ratio exceeds 200. Web stiffeners are required at points of concentrated loads or reactions. 7. IBC 2006, 2009, and 2012 compliant.
