Abstract

fetched live from OpenAlex

The geotechnical resistance factor (GRF) is an important parameter used as a part of the implementation of the load and resistance factor design (LRFD) method. This paper presents the improvement of the GRF used in the design procedure for axially loaded driven piles in Alberta, Canada. To obtain this goal, an extensive database of in situ pile load tests, including the results of 28 static load tests (SLT) and 623 pile driving analyzer (PDA) tests was collected from different locations in Alberta. Various known static analysis methods were used for the prediction of pile bearing capacity based on laboratory and in situ geotechnical tests. The GRFs for the static analysis methods were calibrated using a well-known probabilistic technique, called Monte Carlo simulation (MCS). Calibrated GRF values have been recommended for the design of pile bearing capacity based on the soil type, cohesive fine content along the pile length, different empirical methods, and geological region of Alberta. The results showed that regional calibration of GFR based on the local database resulted in higher values of resistance factors than those recommended in national codes, leading to a more accurate and cost-effective design procedure.

Teacher imitation

Not 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.
