Behavior of Axially and Eccentrically Loaded Trapezoidal Shell Footings Resting on a Granular Assembly
Bibliographic record
Abstract
The objective of this paper is to investigate the behavior of strip shell footings subjected to axial and eccentric loads resting on a cylindrical steel rods assembly that simulates granular soil. An image processing analysis called particle image velocimetry (PIV) is used to obtain the displacement field around the footings. The bearing capacity and ultimate settlements of the footings are presented that show a linear variation with respect to the footing peak angle. The efficiency of eccentrically loaded shell footings is also discussed using settlement and rotation factors. Shell footings are proven to demonstrate better performance under eccentric loading in terms of settlement compared with axial loading cases, while a better performance is found at low eccentricities in terms of rotation. The PIV analysis provided the opportunity for a deeper comprehension of ground wedges beneath the footing and a comparison of results with analytical methods that validated the experimental results. Eventually, an eccentricity factor is proposed for the upper-bound solution to make it applicable for nonaxial loading cases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
