Diameters and dome strength
By increasing the diameter of a dome structure while maintaining its height, the strength of the dome will be decreased.
Domes are architectural structures built to resemble the upper half of a sphere. They can be visualized as an arch that has been rotated around the vertical axis located at its center. These domes can be built over a large area without any need for supporting pillars. The dome construction is also very strong and can withstand hurricanes, tornado and earthquakes.
They are normally used as roofs in cylindrical-shaped buildings or towers. Domes are also used as roofs in buildings that have large floor space but which want to avoid using pillars to support the roof. Some constructions like the monolithic dome are not just roofs, but are buildings by themselves. An example is the igloo, which is built using compressed snow blocks.
Other than their structural soundness, dome-shaped buildings are well known for also being very energy-efficient. The spherical shape results in minimal surface area for the given volume of the building. This means that there is less surface area contact with the surroundings for heat transfer to take place.
