How to laterally brace both flanges?
(OP)
I'm designing a SMF 12 story steel frame building. according to AISC, in SMF, both flanges of the beams must be laterally braced. can anyone PLZ send a detail about this lateral support.
I would appreciate any elp

i attached a picture of my floor system. as u can see the top flange is braced, but i didn't clearly understand how to brace the bottom flange. can u draw ur thoughts with Microsoft paint on the attachment picture plz?!
I really need this information.

If both the beam flanges need to be braced then it would seem that the flanges for the column also need to be braced. If so, how do you do this if you have a glass curtain wall.
If not what is the rationale for bracing both flanges in the beams and not in the columns.

I've checked it and in my country they are designing the kickers for the 5% of the flange compressive strength,
Tanx for the help.
RE: How to laterally brace both flanges?
Beams are usually deep and narrow, which require bracing in the compression zones to maintain a higher allowable stress level.
Columns are often approximately square, which allows it to span longer distances without significant reduction in allowable stress. Where columns are deep and narrow, they often need bracing similar to beams.

Also, the beams connecting to a column at the story levels will usually insure the required bracing.
