Re: [hexayurt] I would like to build a big yurt for burn

Hi Christophe,

If wind weren't an issue at the playa, I think you'd be fine.

However, wind can be a HUGE issue, and is probably the biggest issue (aside from dust and heat/sun).  

I don't see a problem with the 8' high dimension at all, as I built an H13 last year at BM (granted, the winds last year were unusually mild).  

The only issue I see is that 24' dimension, getting torqued on like an oversized lever by strong winds, and somewhere along the length of that taking a little more stress than the rest of the yurt.

No matter what the yurt design/dimension, they all need good strong double-filament tape for having quality hinges, and they all need effective tie-downs.  A rope halo for your design will not be practical, so I would use tape/rope tie-downs with rebar hammered into the ground at certain strategic points around the perimeter of your yurt, coming down from the roofline. Make sure to protect people from impaling themselves on your rebar with tubular foam or even soda bottles slid onto the end of the rebar sticking out of the ground.

I honestly don't know how many tie-downs you'll need off the top of my head, but I would say more is better.  For my H13, I only needed 5.  You will assuredly need more than that. 

Burn on,

-Alejandro

So you mean a 4' high wall, or an 8' high wall - total structure 8' or total structur 12'.

I *really* thing you'll have wind issues with a wall 8' high and 16' long exposed flat-on to the wind. I'm really pretty sure that will fail without serious re-enforcement on the inside, and anchoring the beast will be non-trivial.

*Much* less concern about the 8' high version - that's only a 4' x 16' wall, and if you're really concerned you can put a 2' high wind fence (rebar stakes and planks, say) a couple of feet outside the unit on the windward side to guide the wind up and over the roof.

Even easier, a couple of parked cars!

Build instructions should be pretty much as for the standard 8' hexayurt, but with those additional panels inserted. I'm not sure anybody's ever built one (this is actually one of my favorite designs, and we've never done it!) but these are pretty straight-forwards relative to the various domes etc.

Watch the videos, get the right tape, clean the panels before sticking them (see discussions about solvents etc. and grease coatings on the panels) and you'll be fine.

What's the project?
