Just that a 4x8 solid piece will be stronger than two triangles.

It's only a really small section so Id think the flat roof is fine. What is
the reason for having the pics coplaner? Easier to assemble?

 I solved for the dimensional parameters of this "5-1/2 yurt" in
 Mathematica (the back-wall angle, 112.4°, determines the rest of the
 geometry), and modeled it in Rhino, to figure out area, volume, etc. Here's
 a 5'11" guy next to it.


 


 Here's all the info, compared to other popular designs:



 



 My collaborator here, Greg, has this to say:


 "In the H12, the rope loop and guys pull the roof together and down
 against the walls, and also pull the (tops of the) walls in towards the
 middle. It's a pretty secure arrangement and the net force is straight 
 down.

 In the new design, I don't see a way to neatly pull all of the pieces
 together and end up with a net force straight down... but it may not be a
 problem in practice, especially if the panels are attached securely and the
 structure starts out relatively stiff.

 I'm mostly worried about where the roof attaches to the top of the door
 panel and where the vertical "roof" triangles are stacked on top of the
 walls on either side of the door. In the worst case, if the door panel ends
 up carrying some weird loads that it can't handle, it could be reinforced
 with plywood (as you suggested)."


 But then, those vertical triangles stacked on top of walls also exist
 on the H13, which by now must be considered pretty battle-tested?

It occurred to me that the pairs of triangles that are almost coplanar 
could be made coplanar, and thus made into solid 4x8 panels, if I'm willing 
to split the top irregular piece into two pieces. This would seem to be a 
bit stronger:

It occurred to me that the pairs of triangles that are almost coplanar 
could be made coplanar, and thus made into solid 4x8 panels, if I'm willing 
to split the top irregular piece into two pieces. This would seem to be a 
big stronger. So, I'm leaning this way now. Thoughts? I guess the flat top 
is worse for rain...

Re: [hexayurt] Has anyone built a yurt like this?

[Bob Hearn]

Cool, thanks, guys!

So, nobody's worried about stability?

I'm going to start modding my H12 as soon as I settle on attachment 
strategy (velcro, etc.). I think maybe I can assemble the entire thing 
myself with velcro, and a short stepladder. The top piece is challenging, 
but could maybe be velcroed from the inside, with tape handles inside the 
top piece to pull on to get enough pressure. For rain proofing, maybe 
attach a small nylon skirt to the top piece, that flops over the edges of 
the adjoining pieces, maybe weighted. Elsewhere, orient the velcro seams to 
keep out rain. Also maybe velcro the tarp to the bottom edges.

I have to figure out the roof-section hinge parity, and play with the model 
to convince myself I can attach it to the walls edge-by-edge, without 
assembling the roof as a unit first. Placing the roof on the base of the 
H12 took four of us.

 I've been playing with cardboard models, and came up with this, which I 
 haven't seen anywhere else:



 
  
 
  
 

 It's kind of a 5-1/2 yurt, I guess, made from 13 panels: five ordinary 
 walls, one vertical panel for the door, roof made from six panels, plus 
 the 
 top piece which is an odd shape (4-8-8 isoceles).

Re: [hexayurt] Has anyone built a yurt like this?

[lemondealc .]

Great design Bob. The door is the killer feature for all lived in
structures. I haven't built a hex yet. When I do, this is the design I'm
going to use. Cheers.

[Vinay Gupta (Hexayurt Shelter Project)]

OH I totally wasn't understanding that until I saw the CAD model - I didn't
see how the doorway worked.

That's great! That would be incredibly useful because doors are hard, and
being able to prefab a 4x8 door unit and just drop it into the design would
be great.

Nice work!

[Bob Hearn]

Thanks. However, maybe it's a pipe dream, but I want to be able to set it 
up and break it down solo.

I solved for the dimensional parameters of this "5-1/2 yurt" in Mathematica 
(the back-wall angle, 112.4°, determines the rest of the geometry), and 
modeled it in Rhino, to figure out area, volume, etc. Here's a 5'11" guy 
next to it.




Here's all the info, compared to other popular designs:






My collaborator here, Greg, has this to say:


"In the H12, the rope loop and guys pull the roof together and down against 
the walls, and also pull the (tops of the) walls in towards the middle. 
It's a pretty secure arrangement and the net force is straight down.

In the new design, I don't see a way to neatly pull all of the pieces 
together and end up with a net force straight down... but it may not be a 
problem in practice, especially if the panels are attached securely and the 
structure starts out relatively stiff.

I'm mostly worried about where the roof attaches to the top of the door 
panel and where the vertical "roof" triangles are stacked on top of the 
walls on either side of the door. In the worst case, if the door panel ends 
up carrying some weird loads that it can't handle, it could be reinforced 
with plywood (as you suggested)."


But then, those vertical triangles stacked on top of walls also exist on 
the H13, which by now must be considered pretty battle-tested?

[Hunter]

Velcro has been good to us. ~10 mins setup time. You need one tall person
inside for teardown and two people outside.

[hexayurt] Has anyone built a yurt like this?

[Bob Hearn]

I just got back from Burning Man 2017, using an H12 I bought from Reno 
Hexayurt. I was pretty happy with it (especially when attached to my large 
swamp cooler), but a campmate (also bought Reno H12) and I are wondering 
how best to (1) increase the door height, and (2) speed up set up / break 
down, ideally allowing single-person assembly. I guess an H13 would be the 
default choice for a taller door, but...

I've been playing with cardboard models, and came up with this, which I 
haven't seen anywhere else:



 

 


It's kind of a 5-1/2 yurt, I guess, made from 13 panels: five ordinary 
walls, one vertical panel for the door, roof made from six panels, plus the 
top piece which is an odd shape (4-8-8 isoceles).

One cool thing is that the roof (apart from the top piece) can fold as a 
single permanently hinged unit, rather than the two needed for an H12:


 



So that's an idea for a taller door, slightly less sf than the H12 (which 
is more than big enough for me and my wife), and a lot more head room. But, 
I am worried about stability. Anyone have any thoughts there?

As for quicker assembly, we've been thinking zippers, velcro, rods threaded 
through eyelets, bungie balls, cable ties... I see some good discussion in 
this forum on velcro. But that would seem to still have one of the 
disadvantages of taping the non-permanent hinges, namely reachability for 
the roof section. Zippers you can work from a long pole. Of course for all 
of these you also have the waterproofing issue.

It's a long time to BM 2018, I know, but this is what's in my head now; 
might as well work on it!

Any input would be appreciated; thanks!
