Is it supporting the second floor and attic? What is the joist length on each side of the beam? Will it support any ceramic tile?

Customer: replied 1 year ago.
The Joist length is 12 ft Both ways 2x8 and one bathrooms 5 x 5 Ceramic tile floor only
Expert:  StructuralEng replied 1 year ago.

No. The beam is significantly overstressed and deflection is far too high for even a non tile floor

Customer: replied 1 year ago.
Under the measurements I gave you what is your suggestion for what size and type of a beam to be used
Expert:  StructuralEng replied 1 year ago.

5.25" X 14" 2.2E LVL. That will limit deflection to L/600 for the tile.

Is there a big difference between 1.9 E And 2.2 E having problems finding 2.2 E in my area
Customer: replied 1 year ago.
Are what a steel I-beam be better and if so what size
Expert:  StructuralEng replied 1 year ago.

Hello. There is a difference. 1.9E has 15% lower modulus of elasticity. With a 1.9E you would need a 5.25" x 16" or 7" x 14"

Expert:  StructuralEng replied 1 year ago.

A steel beam would be W8x24, which is 8" deep and weighs 24 pounds per foot.
