Firthy, I'm not familiar with the term "rafter joist." Maybe a local thing. What do you mean?

Drill a hole down the center and insert a carbon nanotube composite rod.
(Explain what you need to accomplish, and whether you're talking about rafter or joist, and maybe someone can offer a more practical solution.)

My house is a bungalow ,I guess you could call them collar ties . The ceilings are fasten to these collar ties see I am putting an upstairs in my house . the roof is famed 16 inch on center ,rafter and "rafter joist", and the wiring is drill through them
firt,
From that little bit iof a description, you are talking about rafter ties/cieling joists.but there is no way to do what you ask with those criteria other than building walls under them to shorten the spans to about 6'. That would make for soem pretty small rooms downstairs.

Dan, that's funny.
I think it would work though!

"Drill a hole down the center and insert a carbon nanotube composite rod."This appears to be the only way to actually strenghen them so far. The other answers shorten the span, which makes them able to support more weight, but doesn't really make them any stronger.
Yeah, I was trying to work within the constraints.

But that would only strengthen it in shear. Need to drill the hole near the bottom of the rafter, then post tension it for maximum stiffness.
Coouldn't you just use a board stiffening tool?Let's not confuse the issue with facts!
I don't think the board stiffening tool will work.
He might try painting them with a thick coat of epoxy.

He didn't specify the dimension in which it needed to become stronger.

I'm guessing he ran out of room in the basement and needs more room to grow his "plants". In which case he wouldn't need much joist strength, but lots of lights...

Why are you trying to strengthen it?

I give up!
But I love a good riddle!

You could say this dilema has me speechless

I'm pretty confident that the answer is "you can't." If I get you right, you want a walkable floor from 2x6 framing, 16" on center, with a 10 foot span. You don't want to remove the 2x6's (good thinking, they're keeping the walls of your house from spreading and the roof from collapsing) and you don't want to add wood to the framing.
Edit [Only option left is to reduce the span. Make your whole first floor a series of tiny little rooms and the new first floor walls will hold up those 2x6 rafterjoists real good.] Nevermind. Piffin already got there.

Everybody having enough fun with Firthy??
Why not just blow him off and suggest he hire a contractor?
Couple of threads like that recently.
Perhaps he could use a studbeam

Oh man.... must be the stress, but you guys are killing me tonight. A studbeam!!View Image
Ok, in the interest of saving you from all these galoots here and getting you a straight answer ...
The way you describe the situation, it probably can't be done. Easiest way would be to remove the wires, add 2x12 floor joists sistered next to the existing first floor ceiling rafters, then re-run the wires along the outside of the attic. But maybe 2x12's are not strong enough. And maybe there's no way to get the new joists up in the attic. You need to give a little more information. Pictures would be very helpful.
Also, is the attic area wide open, or do you have roof trusses that are in the way?

Adding a second floor to a bungalow is a major structural alteration. You need to get plans drawn, and engineered by a structural engineer. Your ceiling joists are just one small piece of the puzzle. There will likely be seismic or storm resistance issues, foundation upgrades, shear considerations, etc.
I wouldn't think of proceeding on a project like this, without an engineered drawing. Once you get that, if you have questions, come back and ask them here. We really will try and help you out. But right now, the info. you've given betrays a lack of seriousness about proceeding properly with such an involved project.
