Background Info A geodesic dome is a partial-spherical shell structure based on a network of great circles (geodesics) on the surface of a sphere. The geodesics intersect to form triangular elements that are rigid and distribute the stress across the structure.
Background Info The geodesic shape is extremely strong for its weight. The surface has a stable structure. The sphere encloses the greatest volume for the least surface area.
Definition The lightest, strongest, and most cost-effective structure ever devised. The geodesic dome is able to cover more space without internal supports than any other enclosure. A light, domelike structure developed by R. Buckminster Fuller to combine the properties of the tetrahedron and the sphere and consists of a grid of compression or tension members lying upon or parallel to great circles running in three directions in any given area, the typical form being the projection upon a sphere of an icosahedron, the triangular faces of which are filled with a symmetrical triangular, hexagonal, or quadrangular grid. (Dictionary.com)
History The first dome was designed after World War I by Walther Bauersfeld. He was an engineer at Zeiss optical company. The dome was created to house his planetarium projector. The dome was patented and constructed on the roof of the Zeiss plant in Jena, Germany. It opened in 1926.
Comparison - Complexity Geodesic domes are comprised of a network of triangles that form a somewhat spherical surface. The more complex the network of triangles, the more spherical the geodesic dome and the higher the class number. A 2V geodesic dome is comprised of only two different sized triangles. A 3V dome is comprised of three triangle sizes. The 4V dome is made of 6 triangle sizes.
Domes in the Real World The practical side of where dome shapes can be found in your every day lives. They can be made from many different materials. They can be found in Architecture as well as many other places.
