SPH Modeling of Extreme Hydrodynamic Forces on Slender Structures
Bibliographic record
Abstract
A three-dimensional Smoothed Particle Hydrodynamics (SPH) numerical model was used to simulate high-velocity bore impacts on structures that can occur during extreme events such as tsunamis, torrential flash floods and dam-break floods. Numerical simulations of the impact of hydraulic bores of varying heights on a slender circular structure are performed. Resulting forces, along with the time-dependent pressure distributions are compared with large-scale experimental results obtained by the authors as part of a comprehensive experimental program conducted jointly with the Canadian Hydraulic Centre at the National Research Council, Canada. This study is a component of a wider scope joint hydraulic and structural engineering research project, whose final purpose is to improve design guidelines for inland structures located in coastal regions prone to tsunami waves attack. The results of this study are also applicable to other types of extreme hydrodynamic impacts and loading such as flash floods and dam-break waves.

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.
