What deflection limit do you need?

Customer: replied 1 year ago.
Whatever it takes to appear straight and not collapse into a room below it.

Will it support any ceramic tile?

Customer: replied 1 year ago.
800lb/sqft is the load it would need to support.
Expert:  StructuralEng replied 1 year ago.

But ceramic tile requires smaller deflection than wood.

Customer: replied 1 year ago.
It would be supporting reinforced concrete with a pool on top. 4ft of water rounded up is 252lb/ft^3 so I multiplied by 3 to get 756lb/sqft for safety's sake then rounded up again to account for a cubic foot of concrete and rebar per sqft.
