Dome calculation tools Below are links to various dome tools for calculating strut lengths, floor area, panel sizes and other useful measurments for building geodesic, segmented and other types of dome. Five in one tool Use this tool to find out floor area, diameter, surface area, circumference and volume of a dome. Not quite finished Trapezium calculation tool Use this tool to find out the strut lengths and panel sizes to build a trapezium panel dome. Wind load calculation tool Use this tool to find out the total wind load on any size geodesic dome. Snow load calculation tool Use this tool to find out the total snow load on any size geodesic dome. More tools coming soon.

Select Hub Size: Select "No Hubs" to get the true "chord" length for each strut, which is the full distance for the strut between each geodesic dome vertex. For most dome construction methods, you will use the "No Hubs" selection. When using our Hubs, the width of our Center Ring must be added to the strut length to give the true geodesic dome dimensions. These hubs are used with 1" PVC pipe for struts. Select Super 6" Hubs for calculating domes with our new 6" Super Hubs, which have a 3. These hubs are used with 1. Select Mega 8" Hubs for calculating domes with our proposed 8" Mega Hubs, which will have a 4. These hubs will be used with 2" PVC pipe for struts. Feet or Meters Click the button for "Meters" if you are using metric measurements. Data Entry: Enter a number with or without a decimal fraction in any of the number fields on the left. For example, enter "5" or "3. All of the other numbers will be automatically calculated. The Blue Struts are always the longest struts. If you know your longest strut length, enter your data for the longest strut length in the Blue Strut field. To build a strong dome, the longest strut should not be more than 6' long.

Keeping the sticks light in weight will help when going to larger diameters. For stick ideas and advice on where to buy them go here.

For a more detailed explanation, click here. NOTE: If you enter a measure in feet, your results are in feet or, in the case of floor area, square feet. Same goes for meters. When entering in feet, decimals are fractions of a foot or square foot for example: 2. The formula is: tip to hole center X 2 X number of struts. For timber domes, angles should be to the nearest tenth of a degree.

Connecting struts There are many types of connectors available for steel and timber geodesic dome. For more information, click here. But to connect them together with bolts, you need to make them longer to drill holes in them. For more information on cutting, bending and flattening struts, click here. The following are guidelines based on international standards. Consult your local fire code for exact capacity. The tables below show sample costs. Material prices listed below vary with suppliers and market conditions. Marine Shrink Wrap 7 mil.

Minimises clashing during the build, keeps the weight down and is a good size proportionately in relation to the hubs and ball connectors. Hi there. This is a free geodesice calc program. Simon, where did you get the chord factors for the 9V icosa? Art project, using a geodesic dome as a structure for a clay project demo. I'm a professional builder who loves making things. For conduit, you can round bend angles to the nearest degree. Marine Shrink Wrap 7 mil. Estimated standing capacity. Any plans to finish off the 4v tools? Hi Paul, Just a heads up, mate. Read more in our guide. Robert Burns -

Hi KB, just curious, what material are you going to build your dome with You can use wider sticks but it does lead to more stress during the build process; the dome is heavier and the sticks are more likely to clash. The tables show sample costs. The 2v seems the most economical for 2. Cheers, Gerry in Quebec. In the case of the 2v icosa hemisphere, the floor is a regular decagon 10 sides. Being bad at math, what I need to know is how much clay will I need to cover a 6' dome with one inch of clay? For stick ideas and advice on where to buy them go here. Hi Enoch A 3 frequency dome is fairly straightforward to make. Hi Rui, maybe I can help.
