Column Bracing - Civil Snapshot
https://civilsnapshot.com/column-bracing/
Column bracing is prevalent in industrial buildings because greater vertical clearances necessitate longer columns. Tall slender columns may be braced about both axes to obtain an efficient design. Undoubtedly, heavy masonry walls afford substantial lateral support to steel columns embedded wholly or partly in the wall.

The 6" by 1/2" plates provide lateral support to each column about their weak axis from the crane girder down. The two columns are NOT braced about their strong axis by the plates. The critical buckling will be, then, about the strong axis (an advantage over not connecting the columns at all).
weak axis Bending R = 3 - AISC

lateral-torsional buckling is a combination of lateral movement and twisting that can occur when a beam is not stiff in the lateral direction. but when a beam is bent about its weak axis, it can’t move laterally because it is stronger in that direction, and the lat-eral effects cannot overcome that. thus, lateral-torsional buckling does not apply …
Column Buckling | calcresource

If no lateral restraints exist across the member length, the weak axis of the cross-section is deflected. For strong-axis buckling to occur, lateral restraints should prevent weak-axis buckling in the first place. Flexural buckling is common for …
Minor Axis Bracing

This assumes that the Engineer is going to specify some kind of bracing at these locations, as is commonly done, as such columns do not intrinsically provide weak axis bracing by themselves. User-assigned brace points, specified in the RAM Modeler by the user with the Layout - Beams - Brace Points command, brace the specified flange.
Designing Built-Up Columns
https://seblog.strongtie.com/2015/09/designing-built-up-columns/
The loss in capacity in the weak axis compared to a solid column is due to the slip between the laminations. Column failure is due to crushing, buckling, or a combination of both modes. Short columns more often experience crushing failure, and …

Vertical bracing Tip 32: Orient columns square to the framing plan when they are part of a braced frame (Figure 15). Braced frame Strive for connections to column flanges in braced frames Braced frame avoid skewed connections to column in braced frames figure 15
Bracing of columns by wall girts - Eng-Tips Forums

With regard to details of connection of the girt to the column, I would think that connecting to the point of center mass (the web) would be the most effective bracing against weak axis bending, but probably least economical. Connection to the flange would impart some twisting in the column.

Weak Axis Moment - Moment about the weak axis of the column (only applicable to "Fixed" base plates). Note: Self-weight of the base plate and anchor bolts are ignored because they are relatively insignificant to the applied loading. Tapered Gusset Plates This entry is only applicable for the Brace to Column Base Plate Connection type.
Solved Column Bracing 1. A W10x33 (A992 steel) gravity

The mid-height weak-axis column brace point is provided by a horizontal member that acts in flexure. The brace can be idealized as a simply-supported member with span of 20 ft. However, the end supports of the brace are fairly flexible, so their stiffness must also be considered as part of the brace stiffness.
