“…Martins et al [24] evaluated the feasibility and costeffectiveness of using shell as the structural solution for the base of industrial vertical silos. In order to optimize the base of a vertical silo, which was originally projected as a solid and flat slab, engineers used numerical computer modeling in the form of a parallel Finite Element Method code to create a shell in the shape of a reversed cone.…”

elucidates the configuration and geotechnical behavior of shell foundations, providing comprehensive insight into their conceptual details, classifications, applications in civil engineering, and an overview of associated experimental and numerical research. Foundations are critical for the transfer of structural loads onto soils. In instances where heavy structural loads must be accommodated by soft soils, shell foundations can present a more cost-effective solution than traditional plain foundations. This implies that shell foundations could serve as efficient alternatives to spread and raft foundations, thereby offering substantial savings in terms of concrete and reinforcement costs. Additionally, inverted segments of spherical domes have the potential to support substantial loads, such as those imposed by water tanks. This study aims to shed light on the efficacy and applications of shell foundations in the field of civil engineering.

“…Martins et al [8] performed a technical and economic analysis of the adoption of shell as a solution for the foundation of an industrial vertical silo, where a rigid and flat slab foundation was initially designed. The results showed that steel consumption was reduced by 23 % of the initial value, while structural concrete consumption was reduced to about 60 %.…”

Traditionally, slab foundation is made up of reinforced flat plates. Replacing these plates by others with a hyperbolic paraboloid geometry can be considered an alternative for structural foundations of residential, commercial, or industrial buildings, especially in soils with low bearing capacity. When compared to traditional slab foundations, the hyperbolic paraboloid foundation reduces the consumption of materials (steel, wood, and concrete), which helps to reduce the environmental impact caused by the extraction of raw materials. Although this type of foundation is easy to build, certain precautions must be taken into account during construction. Therefore, this article describes the practical characteristics related with each construction stage of the foundation, namely the precautions to be taken with the location, excavation, execution of the forms and waterproofing of the foundation modules

“…Ensuring of reliability and safety of operation of metallic silos with the goal of decreasing of foundation settlements is topical both for new building and for objects already brought into operation [1][2][3][4][5] . Taking into account requirements of effective land legislation to efficient land management, new building is planned on plots unsuitable for agriculture.…”

To date, effective codes of Ukraine limit settlement of foundations of metallic silos to 15 cm. To provide normative settlement of foundation with diameter up to 40 m and more is not always possible without additional essential measures for strengthening or changing base soils. Taking into account high levels of loads, soils of bases in natural condition can not carry stress under the base of foundation and require strengthening. Execution of works on change of soils of bases or installation of soil cushions is not always possible taking into account underflooding of territory, building development that exist near at hand, or other complicating factors. Soil cement after Deep Soil Mixing (DSM) technology, Jet Grouting, injection and micropiles were considered for different types of strengthening taking into account application in great volumes. From analysis of the obtained results, it was determined that soil cement after Deep Soil Mixing technology is the most economically justified method. Application of Jet Grouting is justified during strengthening of soil thicknesses locally separated by depth. Injection and micropiles are used appropriately only in conditions of reconstruction under absence of direct access to the base.
