Notes:
– Heights are based on AISI S100-07, North American Specification and AISI S220-11, 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).
1 Web-height to thickness ratio exceeds 200. Web stiffeners are required at bearing points.
*Higher heights can be achieved by using end-bearing stiffeners. See full ProSTUD non-composite charts at clarkdietrich.com.
