Equatorial Bulge



  • Here is a link to basalt mesh...basalt mesh
    I live in an area that may experience a huge devastating earth quake thats long overdue. I was thinking if the mesh is used on the interior, it would prevent any big chunks from falling in.



  • @upwinger ,

    Here is a latenight kitchen table sketch of the block setup like cedar strip canoe cross section with a cove and bead.

    The block concept has a hole in it, 10mm Basalt rebar runs in hole, Mortar in hole.

    I dont know if that basalt would flex enough to follow the radius, And if it did, there would probably need be a centering disk to hold it off the side wall of the hole in the block for mortar to set.

    The so called pony wall is called a ring wall, or at ground level a ring beam .

    I sat up last night and ran Trig calcs on the Planset to get the relaionships of the dome, the equator, the foundation all into cad drawing. Now im puttering around with tape measures, strings, nails looking at what kind of floor space and overhaed space is realistic for living. The wall at equator seems to give the most normal use out of a floor plan. The bulge and return to a smaller radius seems to leave wasted space, but it allows a bit smaller ring beam

    Im starting to find that bulge out and back in to the perimeter beam attractive. Similar to the tumblehome on a canoe hull. More labor in the bulge, more materials and cost in a pony wall.

    Also finding that i dont want domes to intersect. A modular pod system with arch connections is going to mean no shared ring beam or ring wall, or ponywall. Whatever the configuration would be called.



  • I found a Dome Being Bult In Yap, Micronesia, Jon Berger.

    Youtube Video

    "Island Girl Aircrete Dome Home, 6/28/19 update, Yap Micronesia"

    20' diameter dome, Sitting 3 feet on top of a pony wall, Equator on the wall, 13' from slab to top of dome and it is all done with the DomeGaia method of aircrete and construction.

    Ooh Rah!, I can see that it is indeed a realistic way to build. Time to get a foam generator and start a small learner/test project. Will post it when its stitched together.

    @Leonidas I like all these ideas. I am feeling that the rebar is a little bit over engineering though. The bricks are brittle and think that maybe applying a rigid material like rebar will: one, make it difficult in applying, and two, create such a rigid structure that the bricks will be compromised tremendously if there is an earthquake. I love the basalt mesh idea. To me, with this, it will be plenty strong along with the structural integrity of the dome shape itself to resist falling and breaking off. Making something to resist the forces of nature I feel is a fallacy in engineering that is changing. Harmonizing with movement and the natural integrity of natures forms is the way to go. My two cents...you ARE the the engineer though and it will be you and your family inside:)

    Wise words my friend:)

    I want to say a bottom wall to waste level would be fine just not as much aesthetic appeal, maybe, and more floor area to tile and keep clean. I like the idea if its burmed on the outside, or into a hilltop, but you have to think about rain runoff. I was dreaming of a rain catch where three domes intersect. run it into one of the domes and have an indoor waterfall and green room... fresh filtered rainwater pool

    @upwinger Except for humidity problems I love the indoor waterfall idea.

    @upwinger I have thought of water catchment myself. If you do berm all you need to do maybe is ledge the dome with a trough that runs along the side of the dome at a 1/4 inch per foot fall. The fabric and glue would work to do this. It would probably look best if it was below the berm line and graveled so the water falls into the catchment.



  • Hey Folks - My name is Matthew. I have built 3 air - crete domes:

    1. 8 meter diameter in Turkey in 2013. ( https://www.youtube.com/watch?v=OXePjg6A5Kk )
      2928354_orig.jpg

    2. 4 Meter diameter (Rammed Earth fusion) in Spain in 2014.

    3.5 diameter (Stone fusion) in Turkey in 2018.

    I have a diploma in applied Permaculture design from the British Permaculture Association. Here is my portfolio: http://www.holisticprogressiondesigns.com/portfolio.html

    I am based in Turkey & spend time in Spain, but I am open to building in any country in this part of the world.

  • @Ignacio-DHOME Hey my name is Matthew, I am from England & have built several domes in Spain & Turkey. I made rain water catchment for a rammed earth Aircrete dome I built in Spain, here are a few pics...

    @Matt-Prosser Really nice work! clean!



  • Beautiful! Brilliant with the rain catchment. I am curious as to how the aircrete domes are doing in earthquake prone areas so far. It is hard to see the actual inside structure of your buildings so I can't tell if it is the aircrete domegaia type build or different?



  • @ormom8 Hello, Apologies for the delayed response. I have built two domes in Turkey (and I'm currently working on a cluster of three) which is a earth quake prone zone.

    Domes are so strong because there are no corners and the weight of the build is distributed into the foundations.

    I typically don't make my own bricks. I buy prepare one's that are used in mainstream construction, normally Ytong brand. As a professional builder this makes more sense for me.

    Thanks for reaching out and good luck with your project.

    Kindly.

    Matt
