“…The displacement and stress from this model are used as a reference to understand the effect of the lateral shells on the central one at a different distance. The quasi-static approach of moving truck was simulated as presented in previous works [ 14 , 19 , 24 , 25 , 40 ].…”

“…Today, this type of structure is increasingly being used in road, railway, tunneling, and animal overpass projects as an alternative to conventional type bridges, for example, reinforced concrete (RC) slab bridges [ [9] , [10] , [11] , [12] ]. Recent evidence suggests that SSCS is relatively easy to construct [ [13] , [14] , [15] ] and more economical [ 14 , 16 , 17 ] than its conventional counterparts, e.g., concrete bridges. The lack of expansion joints [ 18 , 19 ] and the possibility of forming on weak ground [ 14 , 20 ] are other benefits of such structures (see Fig.…”

“…Anthropogenic soils come in various forms, depending on the technology of their storage (dumping) and usage. At present, dumping (external and internal) is used to create landfills [15,16], heaps and earthwork structures [17][18][19] (e.g., road embankments, levees). Anthropogenic soils, as human-occupied layers, have also shaped the surface and subsoil in cities.…”

The purpose of this paper is to describe the variability of soil rheological properties based on research carried out using load tests of ground anchors under complex geotechnical conditions. The heterogeneity of soil should always be considered when designing geotechnical constructions. In the present case, the earthwork created at the Warsaw Slope revealed an embankment of anthropogenic origin, located in a geologically and geomorphologically complex area of the Vistula valley slope. Excavation protection was anchored mainly in soils of anthropogenic origin. When the acceptance tests of the ground anchor were completed, the subsoil randomness was confirmed using nondirect, geostatistical methods. A standard solid rheological model with nonlinear fitting to the data was used. This model was established to describe the creeping activity of the ground anchor more accurately. The characteristics of man-made embankments were described using the parameters obtained with the rheological model of the subsoil.

“…Soil-shell objects made of corrugated metal sheets are characterized, among others, by the fact that bearings are not used in them. [21] Therefore, the support conditions of the shells are inherently unidentified, which means that the freedom of rotation is not fully preserved (hence, the moments), but at the same time, displacements are still possible. In practice, a design (calculation) scheme is strived to be met, that is, the obtaining of an articulated and non-sliding support in the building under construction.…”

AbstractThe algorithm presented in this paper is intended for the analysis of deformations of shells in the construction phase of soil-shell objects when strain gauges and geodetic measurements are used. During the construction of such an object, large displacement values occur and the impact of axial forces on the displacement of a corrugated metal sheet is small. Internal forces (strain gauges), as well as the displacements of a selected circumferential band of the shell are determined directly from such observations.The paper presents two examples of the analysis of large span shell structures of constructed objects, as well as the assessment of the effectiveness of the finite difference method (FDM) in beam schemes. Good deformation mapping was indicated using the collocation algorithm and the differential approach to the solution when there is a dense mesh and regular distribution of measuring points. In the analysed examples, a significant divergence between the support conditions adopted in the FEM calculation models and the actual static conditions in the objects was indicated. The collocation algorithm is especially designed for such situations. Collocation points in such a solution are used to consider a beam – separated from a structure and without boundary constraints, but with specific changes in curvature – as a reference system, which is determined from the geodetic measurements of two collocation points.
