Joist Support recommendations
I am remodeling the kitchen in my old farmhouse. The floor joists span 13.5 feet and are springy. I want to take a lot of the bounce out. After looking at the options (sistering, steel straps, extra beam, etc), I am considering putting a steel I-beam in the basement, perpendicular to the joists, cutting their span in half. The length of the I-beam would be about 16 feet.
How do I determine the size of beam that I need and how many posts I need? I know a PE would be able to help, but I thought I might be able to short cut it since the beam wouldn't be a critical structural part of the house. I wanted to get an idea of what size I needed so I could get some pricing to determine if this is even a viable option.
