Because the dome's triangular parts are structurally strong and distribute structural stress throughout the structure, geodesic domes can resist exceptionally significant weights for its size. This makes them useful for covering large gatherings or facilities such as stadiums where weight is important.
The geometry of a geodesic dome creates no weak points where a load could concentrate, so it requires very little material to support itself. This means that geodesic domes can be made from very few materials, are inexpensive to make, and require little maintenance.
Geodesic domes also use less energy than conventional structures because they use less material per unit area and are more aerodynamic. They do not need to be built with thick walls or heavy beams, which saves energy that would otherwise be needed to create heat to produce steel or concrete.
Finally, geodesic domes are extremely durable because they have no sharp edges or rigid surfaces that could damage interior equipment or injure people.
Geodesic domes were first developed in the 1950s by Russian-American engineer Louis Kahn. Since then, many other architects have used variations on his design template to create their own geodesic buildings.
The Dome House, nicknamed the "home for the twenty-first century," is an igloo-shaped construction composed of snap-together wall panels constructed entirely of expanded polystyrene foam (styrofoam). The first one was built in 1964 by Los Angeles architect Carl F. Gould II as a demonstration project. It was purchased by its construction company, which still owns it today.
So, a dome house is a type of house built with foam blocks instead of wood. The walls of this type of home are strong and lightweight, which makes them ideal for high winds or earthquakes. The floors of dome houses are usually not flat but rather domed as well - like the roof - to provide extra stability. The ceiling of a dome house is the sky! As far as accessibility goes, all doors and windows in a dome house can be opened. There's no need for doorbells or mailboxes because everyone has access to everything inside the house.
Dome houses were popular in the 1960s when fuel prices were high and builders wanted to create energy-efficient housing. These homes use less material than traditional houses and are cheaper to build. They also allow more natural light into the living space which is good for mood lighting or photography.
Today, dome houses are making a comeback because of their unique design and ability to withstand harsh weather conditions.
The arc (circle) is the strongest structural form, while the sphere is the strongest 3-dimensional shape in nature. The reason for this is because tension is spread evenly along the arc rather of focusing at any one spot. Spheres are strong because they can resist only compressive forces.
The pyramid is the strongest shape when used as a stand-alone structure because its base covers more area than a circle of the same size. A circle has an area of $πr^{2}$, where r is the radius. The base of a pyramid is also a circle with the same radius as the center but instead of being flat it has two opposite and equally sized sides called faces. The base of a pyramid has twice the area of a circle which means it can withstand twice the force for its weight. If a pyramid were made from material that could resist compression instead of tension then it would be stronger yet because there would be no stress points to break down under pressure.
The box is the strongest shape when used as a stand-alone structure because it can resist both compressive and tensile forces. A box with dimensions of length x width x height can withstand forces up to mass x length/width x height.
Symmetry is important when constructing strong structures. Anything with symmetry functions similarly to a pyramid or box - areas of equal strength and weakness.
