Composite Table Notes:
Allowable composite limiting heights were determined in accordance with ICC-ES AC86-2015.
Additional composite wall testing and analysis requirements of the SFIA Code Compliance Certification Program were observed.
In accordance with current building codes and AISI design standards, the 1/3 Stress Increase for strength was not used.
The composite limiting heights provided in the tables are based on a single layer of type X gypsum board from the following manufacturers: American, CertainTeed,
Georgia Pacific, Continental, National, PABCO, and USG.
The gypsum board must be applied full height in the vertical orientation to each stud flange and installed in accordance with ASTM C754 using minimum No. 6 Type S
Drywall screws spaced as listed below:
Screws spaced a minimum of 16 in on-center to framing members spaced at 16 in or 12 in on-center.
Screws spaced a minimum of 12 in on-center to framing members spaced at 24 in on-center.
No fasteners are required for attaching the stud to the track except as detailed in ASTM C754.
Stud end bearing must be a minimum of 1 inch.
f: Adjacent to the height value indicates that flexural stress controls the allowable wall height.
s: Adjacent to the height value indicates that shear/end reaction controls the allowable wall height.

Non-Composite Table Notes:
Heights are based on AISI S100-12, North American Specification, and AISI S220-15, North American Standard for Cold-Formed Steel Framing - Nonstructural Members,
using steel properties alone.
Above listed Non-Composite Limiting Heights are applicable when the unbraced length is less than or equal to Lu.
Heights are limited by moment, deflection, shear, and web crippling (assuming 1" end reaction bearing).
Heights labeled with a "*" can achieve higher heights by using end-bearing stiffeners. See full ProSTUD non-composite charts at clarkdietrich.com.
