https://www.ziptiedomes.com - This video shows the advantages of building the shorter 3/8 3 frequency geodesic dome, as compared to our standard 5/8 3 frequency geodesic dome package.
In the design of the 3/8 geodesic dome, the vertical equator section has been removed, as compared to the 5/8 geodesic dome, yet the 3/8 dome has the same amount of floor space as the 5/8 dome.
The height of the 3/8 geodesic dome is 10' 5", as compared to 14"9 for the 5/8 geodesic dome.
There are many advantages to this design.
Besides using less struts, hubs, and covering material, the dome only requires an 8 foot stepladder for construction, which makes it much easier to build than going up and down the 12' stepladder for the 5/8 dome. There is less of a wind load on this dome, so the need for extensive ground anchors in areas with high winds is reduced.
These domes were originally advertised as having a 24 foot diameter, based on the 5 foot "A" strut length. Upon observation, with the inclusion of the 2.375" OD center ring in the hub added to the strut length in the calculation of the dome size, the actual size of the dome is 25' 2", giving a dome floor area of 499.5 square feet.
