Brad,
Perhaps a better look at the form is in order.
The form template can be used for either longitudinal or lateral seismic
bracing.
Should the form be used for calculating the longitudinal bracing Fpw the
limitations in 9.3.5.5.2 do not apply. The clarification of this is
provided in the text of the section which notes, in part, "_*Lateral*_
sway bracing shall be in accordance with either Table 9.3.5.5.2(a)
through Table 9.3.5.5.2(l)..."
As I am a member of the hanging and bracing committee please see the
disclaimer below.
sincerely,

Please refer to NFPA 13 (2016).
Figure A.9.3.5(b) is a sample sway brace calc.
at the bottom it says "Maximum Fpw per 9.3.5.5.2 (if applicable)."
My question is--
are those max load tables based on lateral brace spacing ever NOT
applicable?
thanks,
Brad
