Side sway web buckling mechanism for moment connection?!

[Alaazaki]

Hi,
Could you please help me if any one have a video explain the mechanism of Side sway web buckling for moment connection.
I search for it in the youtube but I didn't find anything related to this subject
thank you in advance.

I don't think that is possible - sidesway web buckling occurs when you have a largely unrestrained compression flange, and a standard moment connection should restraint it plenty.
