A dome (Italian cupola - dome, vault, from Latin cupula, diminutive of cupa - barrel) is a spatial supporting structure of a roof, close in shape to a hemisphere or other surface of rotation of a curve (ellipse, parabola, etc.). Dome structures cover mainly round, polygonal, elliptical in plan rooms and allow to cover significant spaces without additional intermediate supports. The forming forms are various curves, convex upward. From the vertical load in dome structures, compression forces arise, as well as horizontal thrust on the supports.
