Abstract
A series of cyclic direct simple shear tests are conducted to investigate the effect of static shear stress on stress-strain-strength behavior of Ottawa F65 sand at three distinct relative densities (50%, 60%, and 90%). The new experimental data supplements the LEAP-2022 data (Lbibb and Manzari, 2023) in which the effects of overburden stress, relative density, and static shear stress on cyclic strength of Ottawa F65 sand were reported for relative densities of 55%, 66%, 71%, and 75%. The report provided along with the datasets presents the setup and experimental procedure, as well as the liquefaction strength curves and the results obtained from each test. The dataset presented in this report builds on the soil characterization tests, cyclic triaxial tests, and direct simple shear tests performed for the LEAP-2017, LEAP-2018/9, LEAP-2020 (ElGhoraiby, Park and Manzari, 2017, 2018a, b, 2020), and LEAP-2022 (Lbibb and Manzari, 2023). Along with the current dataset, archived on DesignSafe-CI, a MATLAB script is also provided for post-processing and visualization of the experimental data.

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 it
