Abstract
The use of integral abutments to accommodate thermal expansion of bridges is common practice in Canada, and is also seen throughout the World. The main benefit of integral abutments is the complete elimination of the expansion joints and bearings, which are expensive to install and maintain during the lifetime of the bridge. During seasonal temperature change, the structure undergoes expansion and contraction, moving toward and away from the backfill. This movement causes sequentially variations in stresses in the backfill behind the bridge, in earth pressures acting on the abutment, and in the stresses in the supporting piles. Integral abutment bridges are generally characterized by their complex soil-structure interaction of the abutment walls and foundations as they are subjected to cyclic loading on a daily basis. As the backfill soil of such bridges is subjected to loading-unloading-reloading process during which the stiffness of the soils keeps on changing, the soil stress-strain behavior is complicated and special modeling procedure is needed. This paper investigates different aspects of integral abutment bridges analysis and there implications on the predictability of the employed finite element model.

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.
