“…It can be due to the fact that the shell footings extend the failure zone into the depth of foundation, tending to provision of more resisting force against failure. This is in agreement with experimental studies of other researchers [3,9,32].…”

“…Shells are thinwalled structures which obtain the stability and bearing capacity from their specified shape. This characteristic enables them to create maximum structural efficiency with minimum materials [1][2][3][4]. From geotechnical point of view, the specific performance of shell footings has been directly related to different shapes including conical, pyramidal and triangular shell strip footings [4][5][6][7].…”

This paper investigates the response of triangular shell strip footings situated on the sandy slope. A series of reduced-scale plate load tests were conducted to cover different parameters including three shell footing types with different apex angles in addition to a flat footing, four different distances for strip footings from the crest of the slope namely "edge distance" and reinforcement status (unreinforced and geotextile-reinforced statuses). Bearing capacity of shell footings adjacent to crest of the slope, bearing capacity ratio, shell efficiency factor, influence of apex angle on settlement of footings and the mechanism of slope failure are discussed and evaluated. Also, empirical equations for determination of the maximum bearing capacity of triangular shell strip footings are suggested. As a whole, it has been observed that decrease of shell's apex angle as good as increase of edge distance could significantly improve the bearing capacity. However, as the edge distance increases, the effect of apex angle on the bearing capacity got decreased. Also, it was found out that the beneficial effect of

“…Depending on the apex angle, the bearing capacity of shell foundations in flat ground conditions is in the range of 8%−18% more than the simple foundation. This can be attributed to the fact that the shell footings extend the failure zone into the depth of the foundation to provide more resisting forces against failure, which is in agreement with previous experimental studies [8,14,33].…”

From a financial point of view, urbanization frequently enforces the clients to construct superstructures near the slopes, giving rise to increasing the risk of building instability. By conducting a series of small-scale plate load tests, this work aims to investigate the effects of installing geotextile reinforcement layers in sandy slope and reducing the apex angle of triangular shell strip footings. The results show considerable effect of using geotextile-reinforced layers and decreasing the apex angle on the ultimate bearing capacity of shell foundations. With increasing foundation distance from the slope, the adverse effect of the slope is reduced. However, as the distance decreases, the effect of reinforcement and apex angle is increased. For practical applications, empirical equations are also presented for determining the ultimate bearing capacity of the footings and scale effect as well. Finally, 3D numerical simulations are executed and compared with the experimental results.

“…Numerical limit analysis for both surface and embedded foundations demonstrated reasonable agreement with model testing. When the interface condition at the base and side of the foundation was progressively shifted from smooth to rough, the findings revealed that the bearing capacity of T-bar, shell block, and rigid block foundations increased [9].…”

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.
