SecTion ProPerTieS For HaT SecTionS

1. Hat Sections are attached adequately to the underlying support members (purlins or joists) so that the panels remain

substantial in their original roll formed shape as they are being subjected to load.

2. The allowable spans are calculated for strength only. The Hat Section was not checked to determine if bearing controlled the

allowable load.

3. Hat Sections are fully braced as per AISI Cold Formed Steel Design (1996 Edition with supplement 1) Manual requirements.

4. Section properties of the Hat Sections are based on the requirements of the AISI Cold Formed Steel Design (2001 Edition)

Manual.

5. Self weight of the Hat Sections has to be deducted from the allowable inward load to arrive at the actual "live load" carrying

capacity.

6. Deflection consideration is limited by a maximum deflection ratio of l/180 of span.
