Resumen
Today, with the advancement of science and technology, there are new needs and demands in the field of structural engineering. The time factor in constructing structures has doubled, and this has increased the tendency towards prefabricated structures. Also, with the increase in human populations, there has been a strong interest in having large spaces without the presence of middle pillars. In this regard, from the beginning of the century, a number of experts were attracted to the unique capabilities of spacecraft. With the publication of these results, the field was welcomed more and more day by day, with the passing of several decades, the study of space structures is still at the center of the experts and students of civilization. If the grid is curved in two directions, it is called a dome. Perhaps a dome is a part of a sphere or a cone with multiple joints. In general, domes are highly rigid structures. Examples of domes can be diamonds and gyodecic domes. In this paper, geodesic domes have been analyzed from the point of view of the discussion of structures of dome space spaces in the geodesic dome. A geodesic dome (or a dome constructed with geometric surfaces) has a spherical or semi-spherical shell structure or a grid shell based on a grid of large interconnected (geodesic) loops on its surface. Geodesic domes are formed by subdivisions. Polygons are more stable because they form triangles at any time. The geodesics cut each other to form triangular elements to increase their internal strength and also increase the power of distribution of stress at the level of their structure. With more divisions on the surface, the dome gets smoother and more flexible.
