Double 2x4s for Deck Joists.
We currently have a 2-story deck that extends the length of the house and extends 8' out.
I'd like to extend it to 16'.
There is a deck on the top story, and on the story below.
The house is on a hill, with the top story the entry floor.
It currently has (basically) single 2x6 beams.
Ideally I would like to have the supporting beams 16' out from the house so that the bottom deck does not have beams in the center of it, and at the end.
I have an opportunity to purchase 100 2x4x16 at a very nice price, and am wondering if doubling up on the 2x4's will suffice?
If I have to keep the supporting beams at 8', then another at 16', I can do that & live with beams splitting up the lower deck.
Also, if I do that (beams at 8' & 16') I can use the 8' 2x6s from one of the decks and use them for the other deck, right?
Thanks in advance for any help.

2x4's are never used as structural components, for what you are considering I would strongly suggest you get an engineer involved to calculate the loads!

A single 2x6 is not a beam. Sounds like you need to start over, sorry to say.

You could use the 2 X 4's as decking if they're a really good price, but not for structure. The deck you are describing is a complex structure. Should it collapse it could cause a fatality.

2x4s have very little ability to carry a load; they are simply not up to the task.
As mentioned earlier, your concept is complex enough you probably should have an engineer involved.
