overhang questions

OK, ok, back to the original post.. support can be done - I didn't listen hard enough.
I've never seen people using trusses for these kind of overheads (though I'm sure they do in the wider world of architecture/building), and I beg your pardon for my exploratory posts. I figure the trusses are as strong as their connections - me, I'd look to the connections., what is going on with that.

Time for me to add I'm sorry for spouting off. Trusses for an overhang are new to me. They, like everything else, are probably vulnerable at the weak point(s).
Support sound good (see if you can avoid putting the column in front of the window if there is one), but I wonder about the original connection and design.

I'm trying to visualize the situation osso.
Let's say the front door is located right about where the letter A is...the rest of the distance to the end of the truss would be cantilevered. Darcey is talking about siting a beam at the far left end of the truss to shore up the overhang...is that what you see?

I'm perplexed and don't know what I see. I get there is a W. Plus a W behind what you show in the drawing. Not clear if I get there is a P, will have to reread. I have a bad habit of skimming since I think I get something (slaps self). Will go back and read one more time.

W is the rear wall(side view)

If you shift P(front wall) out to A it approximates where the front wall is and where the cantilever starts

Yeh, but did Darcie say there is a P? Probably... I should read more closely.

And there is, presumably, a back wall, shoring up the ridge beam that is attached to the said truss. Or are there no ridge beams with trusses? I know nada about trusses.

I think Darcie said it was a truss roof

Yes, and then.... do all truss roofs have a central post (to me, a 'column' in nomenclataure because of the weight)?

as you can see osso, trusses erase the need for ridge beams and such. I don't know if this is what darcies roof is built like

no, they span from the front wall to the back...without support in the middle...unless the span is too big

Thanks, that helps (oh, how times change in a few years). Somehow I still think they need ridge beams, or long steel ties. Oh, well. Yes, I get the roof gloves it all.

So, you take this scenario as half of the contraption/truss is hanging out there sans support?

I'm odd, of course. I'd support such a thing at both ends, and/or somewhat in from the ends, with columns/posts, assuming the window, if there is one, is central.

My firms tended to go for beef re support, but I'm from California.

I still don't get it. They span from the front wall to the back? I'm taking it that the truss lines up with the front of the house. No?
Presumably the truss in front is resting on P, no? I can see that working if the truss and P were tied with corbels or serious steel angles, or if soil never ever shifted.

Meantime, it's hilarious to talk about all this in just words.

...don't you just love it?

Did you draw that, Panzade? Imagine the shear forces on that gang plate at the peak. Holy doodle dandy! I kinda just glossed over it when I saw that you and Osso were on it.

I don't know which part of Manitoba this is but a snow load closer to 40# per square foot might be more like it.

But I'm being more than usual stupid re being any help to the original poster. I simply don't understand whatever support there is.
On shear, I was raised tough on that in earthquake country. And I know Panz has experience re shear.
But my stupidity is in just comprehending what is going on.



The original poster hasn't been back, that I know of, but I remain interested.

JTT, stupid here, what is the gang plate (that simpson thing?)

Er, that Simpson thing and its short lil nails?

Yup, Osso, a piece of lightweight perforated steel. The perforations create many little "nails" on the business side.

So, no beef..

I meant nails, you know the ones I mean, thickish things of something like 1 - 1/4 or 3/8 inch, um, 1/4 or 5/16 thick?), but you are talking about something like perforation teeth (which I don't know about). Little value...

Not that the usual nails would do it in the circumstances you say.

This seems lame, if I begin to understand it.

Meantime, or earlier -
I'm not a contractor, but have long been occupied with stuff about building. For a while I had a whole bunch of unpopular threads on a2k with building news kind of stuff.

Some of my interest was towards small places of various sorts. Unfortunately, some of the most interesting small places cost a whole lot of money, but there were others that were not all that pricey. One can look up all those, I think, by putting landuse into the google white space at the top of the page. Or maybe architecture. I tagged them, but it was a while ago.

But -
my main interest may be how to make small places that withstand hurricanes in Florida and snow in Manitoba and don't cost zillions of dollars. Mobile homes in Florida don't need to be shitty - or do they? My in laws lived in a 'coach', which I took to be vulnerable.

Maybe that's hubris, was their place more vulnerable than mine? Let's say it was for arguments sake, and talk about making it stronger.
