How do I build a partition wall underneath an I-beam?

We are developing the basement and plan to build a partition wall directly underneath a steel i-beam. How do I attach the top plate to the steel beam to build the wall? I've attached a picture showing the beam and construction around it. The beam only is 6" deep and 3 3/8" wide.

I considered drilling into it. I'm no engineer, but feel like it might have some kind of effect on the structural integrity of the beam and am hesitant to go this route.

Any thoughts?

The best way is to stick frame a 2x4 wall directly below the steel beam. You level down from the 2x4 plate above the beam and put them arc on each side of the floor then put your bottom plate down and stick frame each stud 1x1 nice and snug with a top plate attached with PL caulking to the underside of the Steal. Once you're done framing whole wall you shims to make it really tight. You're good to go no need to screw into the steel.

You can secure to top plate with pl premium but be sure to put a double plate at top or bottom leaving minimum 3/4 " space between plates.

You can attach a 2x4 to underside of beam for a wall. The wall is non-loadbearing so you would just be using the beam to secure it which is no problem. You can Ramset it.

Hope that helps.
