Effective section modulus Se is computed using effective widths of elements. (Reference AISI B2, B3 and B4)
Ptf is the compressive axial strength for section having one flange attached to a qualifying deck or sheathing with qualifying fasteners. Ptf is computed assuming the fasteners are centered on the flange. (Reference AISI C4.4)
Appropriate factors of safety have been applied. (Reference General Information)
Consult General Information for definitions of symbols used in these tables.
Capacities are for combined shear and bending in the absence of axial load.
Values in tables are for sections supported laterally at both flanges, for their full length.
For a section to qualify, the applied shear and bending forces must each be less than the values for a paired V and M in the table.
Appropriate factors of safety have been applied. (Reference General Information)
Capacities were computed assuming the use of plates or clips at supports which will effectively transfer loads directly to the web of the member. If sections are to bear directly on the supports, the sections must be checked for web crippling.
For special conditions not covered in the tables, or for selecting sections for a specific application, contact your supplier of LGSI sections.
When selecting sections for a specific project or application, compliance with the provisions of relevant governing codes and specifications, including computation of applied loads, is required.

Capacities were computed assuming the use of plates or clips at supports which will effectively transfer loads directly to the web of the member. If sections are to bear directly on the supports, the sections must be checked for web crippling.
Deflection values are the amount of deflection that occurs when the full allowable load is applied. For applications with special deflection requirements, it may be necessary to adjust the allowable capacities.
