Hello

Expert:  StructuralEng replied 1 year ago.

Southern pine is the strongest dimension lumber. Oak is denser, but southern pine is stronger.

Is it supporting one flop only or an attic, too? What is the joist length on each side? Will it support any ceramic tile!

Expert:  StructuralEng replied 1 year ago.

One floor only...

Customer: replied 1 year ago.
the joists are 2x10 and are 14'. there is no tile above it. the 2nd floor above is only a guest bedroom.. no attic. it is an old cape
Customer: replied 1 year ago.
does it matter that the beam will not be dry. I know it will shrink, check and crack but that will be part of the look as long as i don't compromise the structural integrity
Customer: replied 1 year ago.
1 floor only
