Do these single plate connnections provide enough torsional restraint to brace the top of the top column?

A shear tab connection primarily resists vertical shear. The equation I gave earlier was Equ. 8 from “Hollow Structural Section Connections and Trusses” by Packer and Henderson. When testing this type of connection, they found only one limit state for an HSS column. This led to the equation given in my earlier post. Yield line distortion of the HSS wall was never a critical limit state because the end slope of a simply supported beam is limited. However, if the shear is accompanied by axial force, the wall of the HSS must be capable of resisting the axial force.
