I am doing a remodel on a 2 story home and would like to

Customer Question

I am doing a remodel on a 2 story home and would like to increase the ceiling height on the lower level.
The floor joists are 2x10's and I am proposing to use a steel c channel sistered to the remaining 4" of the existing joist once I rip it down. I will use the same channel material bolted to the band board for bearing.

Hello

Expert:  StructuralEng replied 1 year ago.

What is the joist span? Will they support any ceramic tile?

Customer: replied 1 year ago.
Span is 14' and no ceramic tile

Are you asking about structural steel channels?

C4x7.25 for 16" spacing

Expert:  StructuralEng replied 1 year ago.

It's late and I have to go to bed, but there is the size. Good luck with your project!

Customer: replied 1 year ago.
Thanks. I was wanting to use C4x5.4 @16"o.c with 1/2 thru bolt @ 24" o.c to the remaining 4" of joist.
Expert:  StructuralEng replied 1 year ago.

That just barely works for deflection and the wood will be over stressed because the steel isn't stiff enough to attract enough load away from the wood.

Thanks. If you think 3/8" or 1/2" angle with a 4" vertical leg will be stronger that's always an option.
Expert:  StructuralEng replied 1 year ago.

Angle 4x4x3/8 is the other option.

No problem. I'm happy to help. Good luck with your project.
