Lateral Bracing Strength
Lateral Bracing Strength
(OP)
Is there any information on strength requirements or required cross section of lateral bracing? AASHTO code gives minimum spacong criteria, but no information on the strength required to consider a point braced.

I use about 10% of the load on the beam. When applied to a tension member, 10% usually gives a fairly small brace.
Beef it up if it's for a crane beam or other dynamically loaded structure.

Fs(tension/compression) = (0.015+0.008*(L/r-60)) * Cf
Cf = axail design compression of supported member
Hope this helps. Have a nice day!
