1. Theoretical section properties have been calculated per AISI 2007 'North American Specification for the Design of Cold-Formed Steel
Structural Members'. Ixx and Sxx are effective section properties for deflection and bending.
2. Allowable load is calculated in accordance with AISI 2007 specifications considering bending, shear, combined bending and shear and
deflection. Allowable load considers the 3 or more equal spans condition. Allowable load does not address web crippling, fasteners,
support material or load testing. Panel weight is not considered.
3. Deflection consideration is limited by a maximum deflection ratio of L/180 of span.
4. Allowable loads do not include a 1/3 stress increase for wind.
5. Diaphragm Capacity - 296 plf average Ultimate Shear Strength using the above fastening pattern on 2x supports located 2' on center,
per ASTM E 445.
