Steel Lintel for Existing Concrete Opening

[cmrazik]

On one of my buildings the subcontractor increased the size of the louver openings in the basement walls. As a result I can not longer rely on the reinforcement in the concrete to carry the beam.

I was hoping to install a channel on the inside face of the wall to span the opening and carry the load to the concrete walls on either side. (Installing a lintel on each side of the wall is not an option, nor is putting a support inside of the opening.)

Is there a way to view the channel and concrete beam as a transform section? From what I have read both materials have to have elastic properties.

Thanks so much!

I would think the channel could carry the load, and the concrete could resist the torsion due to the channel being on only one side of the wall.
