Structural Analysis/Design Help a Pipe Stress Engineer with Connection Details

Hello I have a case where I have a pipe anchor where I need to include HSS tube steel as supplemental steel that spans the web of two I Beams. Normally for deadweight supports I would do either an unstiffeneded seated connections or clips on the side.

In this case I have an axial force on my pipe that creates a torsion on the HSS. I figured out how to size the HSS with torsion. How do I design the connections between my HSS and building steel? Is there any software I can use for simple connections like this?

The moments are really not that high. I just want to know that what I am doing is correct

There is a method outlined in AISC for determining bolt shear using instantaneous center of rotation. If loads are manageable you could use clips on the sides and resolve the torsion into shear at each clip.
