bottom loaded wide flange 3

[JTPE]

If a beam is loaded at the bottom flange only, does it still need to be laterally braced? In the case I am considering now, the bottom flange is equally loaded on each side of the web by a hanging wall. I realize there are several considerations such as flange bending, section modulus reductions because of connections, etc, but in regard to bracing I'm having trouble.

It seems to me that for the compression flange (the bottom flange)to buckel out of plane it has to overcome the "resisting" force which is the load itself. Does anyone have any suggestions, or perhaps a code that describes these situations.

Thanks
