Using thin curved plates in achieving structural elements is indicated because of their many advantages (low weight and relatively simple efforts state). At foundations that are usually elements of great mass and volume, the use of curved thin plate is advantageous, because the increase of their mass is achieved by filling the strength structure (light) with cheap material (lower class concrete, ballast, earth). Also, curved thin plates used in constructions represent one of the most rational uses of construction materials whereas, especially in achieving the so-called membrane state, concrete and steel, which compose the strength structure, may be solicited to bearing capacity limit.
