Plans for a 100ft low profile domeOK a 100ft dome in a trapezium style I think was the brief, the 16 sided trapezium dome would I think require the panels to be massive so I''ve quad divided the basic shape and lowered it by about half. This makes for 32 panels around the circumference.  Let me know if we''re heading in the right direction with this? |

| 100ft is a big dome. I`d be tempted to build a small prototype to test the design first, before spending a lot of cash :) The low profile tends to make for shallower angles which could cause panels to invert (pop-in) in a similar fashion to high frequency standard geodesics. | |

| The drawing you have here would be ideal for what I need.Just as long as the ceiling is not over 25-28'.I like the design.On a 6 or 8 frequency triangle dome there are alot of different strut lengths and angles to deal with. | |

Here is a side elevation, let me know if you need the dome made lower? I did'nt want to make it too low because the roof at the top of the dome gets very shallow when you lower the dome. I thik the height comes in at roughly 30 feet I would recomend removing the bottom layer if you want to go lower Let me know what you think. |

| If the dome is likely to see any snow a flat top is not a good plan :) With conservative live and dead load figures the domes 32 base panels may need to support just over 7 tons each ;) | |

| A dome of this size would require a considerable foundation, if you allow 20 inches of elevation above grade you need to adjust dome radius accrodinly. Snow load could be accomodated by a center pole with attenuated trusses af little depth. A 20 " elevation at foundation top would allow for mechanical penetrations required by electrical ,heatin and plumbing systems, as well as provide adequate moisture protection. center pole could provide basis for elevated floor system, once again allowing for installation of mechanical systems | |

| Does anyone know who sells 65 foot low profile dome kits? | |

| Why would you want to buy one? It would kind of defeat the main reason for Paul (Admin)working hard making geodesic information freely available on his website :) "The main purpose of geo-dome is to educate and promote the design, construction and use of dome structures and efficient building design for the environmentally conscious self builder" | |

| Hello Colin, I've taken the stated purpose to heart and have attempted several postings aimed at my education re: trapezium dome design. In particular, I've been unable to download the AutoCAD files posted for any of the domes. I.E. cannot find the URL. Can someone send me a CAD file for a Trapezium dome? Thanks mikechastain@austin.rr.com {Texas} | |

| exactly what I am looking for! What about the dimensions of the eight different shapes? | |

| i owned a two court air structure over two clay tennis courts.i want to replace it with the frame that's approx 100' diameter. i want a frame only and then cover it with a sleeve that will allow light in. the foundation is 2' wide and 4' down in southern NJ. e-mail me with thoughts please. | |

| Could I get a copy of this plan? I'm thinking this would be an excellent house if I could put a load bering center column in to hold my local snow load (Colorado) | |

| All this is wayyyyyy over my head. Where do I start to understand this ? Books articles ? Tey all seem assume you understand all the basics. And what material would you use for a 100' dome. All I've seen for the most part is electrical conduit | |
