Geodesic dome-an architectural structure in the form of a sphere formed by connecting rods in triangles on the cellular principle. The principle of building a dome-shaped frame was developed by the American architect Richard Fuller based on the geometric shape of the Earth in the 1950s. The surface of such a dome consists of steel ribs of different lengths, which when combined form the shape of a dome. The practical application of the building contour geometry proposed by Fuller is based on dividing space by vectors. The basic unit of this division is the tetrahedron. The above separation allows you to achieve optimal space filling and the most complete use of the structural strength of materials.

In a sense, then, a geodesic dome can be thought of as a sort of space-frame-like or latticed structure applied to the enclosure of a spherical space. It is an extremely lightweight system that is able to cover a very large space by means of the interplay of many small, short elements. Moreover, as we will see later in this chapter, the lightness and efficiency of domes in general as an overall system for carrying load means that very large spans and enclosed volumes of space can be achieved with support only needing to be provided around the base perimeter of the structure – i.e., without any interior and space-intervening columns.
Free vibration of paraboloidal dome/shell with arbitrary parabola meridian

Domes have a long architectural lineage that extends back into prehistory and they have been constructed from mud, stone, wood, brick, concrete, metal, glass, and plastic over the centuries. The symbolism associated with domes includes mortuary, celestial, and governmental traditions that have likewise developed over time.
Buckling of externally pressurised ellipsoidal domes with variable wall thicknesses

The domes are useful structural components, being lightweight, having an enclosed volume, and withstanding external pressure. Spherical domes have attracted much attention because of their high load-carrying capacity (Pan and Cui 2010; Zingoni 2015). Spherical domes are typically applied in the aerospace industry, as well as the underwater industry, where they can close the forward ends of submarines (Jasion and Magnucki 2015; Thompson 2015). However, spherical domes are highly imperfectly sensitive structures and prone to buckling failures. The buckling performance is strongly influenced by initial shapes, wall thicknesses, and geometric imperfections of domes (Lee et al. 2016; Ifayefunmi and Blachut 2018). Therefore, it is urgent to develop a novel dome structure for underwater pressure shell.
Load bearing of corroded shells under external/internal pressure
Published in Journal of Structural Integrity and Maintenance, 2018
Apart from torispherical closures of cylindrical pressure vessels, the domes can have different shapes. This can include, for example, ellipsoidal domes. Geometry of the latter is shown in Figure 4(a). Buckling modes of oblate (A/B = 0.5) are depicted at Figure 4(b) whilst the eigenshape of prolate ellipsoid (A/B = 2.0) is illustrated in Figure 4(c). The magnitudes of bifurcation buckling pressures, pbif, and collapse pressures, pcoll, for both domes are given in Table 2. These were obtained for: E = 207 GPa, σyp = 414.0 MPa and elastic, perfectly plastic modelling of steel. It is seen in Figure 4(b) that for oblate dome (A/B = 0.5), the failure area occurs at the apex. The opposite situation exists for prolate head (A/B = 2.0), i.e. eigenmode’s deformations occur at the equatorial base with n = 10 circumferential waves – as depicted in Figure 4(c). This observation is important in view of corroded area being in the “buckling zone” of a head – as discussed later.

The structure of the dome is made of steel and reinforced concrete. The different elements of the steel structure are joined together by rivets. Anchor plates are also used to reinforce some knots (Figure 17). In the dome, steel structures are composed of approx. 1250 Ton of Carniege beams, manufactured by the United States Steel Products Company and designed by Purdy & Henderson (Silva González 2006) (see chapter 3.4)
