Column Forces in a Buried Modular-Polymer Stormwater Collection Structure from Design-Truck Loading
Bibliographic record
Abstract
Results from full-scale physical experiments are reported to quantify the column forces that develop in a modular, polymer stormwater collection structure when buried at its minimum soil cover and subjected to design-truck loads. Columns located directly beneath the load pad experienced the largest increments in force from surface load. Load was also transferred through the soil and the structure to nearby columns. The four central columns carried on average 31% of the applied nominal design-truck load. Column forces from backfilling were found to be only 10% of the response from surface load. Factored column demand at the service design load (107 kN) was equal to 0.45 and 0.64 times the buckling resistance of the 0.6-m and 0.9-m-long columns tested. For the conditions tested, the columns satisfy AASHTO load and resistance factor design requirements against individual column buckling with a resistance factor of 0.7.

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.
