Slenderness In Roof Bracing

[Ganesh Persaud]

Hello Everyone,

Is it necessary to check slenderness of pipe roof bracing elements?

Yes, if the braces are in compression. Not so much if in tension, but the sag should be limited.

Note that some building codes in high-seismic areas will mandate minimum L/r ratios for bracing regardless of whether they are tension/compression or tension only. This is necessary to ensure sufficient ductility of the overall framing system.
