What is the span of the beam? What is the length of the joists that frame into it? I assume they're on one side only? It's supporting a single floor only? No attic and no roof?
Thank you. Give me a few minutes to run some numbers.
UC 152x152x37 is the smallest I beam you can use for this condition.
I selected the most shallow size to give you as much clearance as possible. The 203x102x23 will work, but only if you can provide lateral bracing to the beam at the ends and at the quarter points of the beam.
