Performance of one-way reinforced concrete walls subjected to blast loads
Bibliographic record
Abstract
The performance of one-way reinforced concrete walls in resisting blast loads is numerically evaluated in this paper.Reinforced concrete wall strips of dimension 4.0 × 1.0 m and different thicknesses and supported on two sides spanning in the long direction are subjected to blast loads produced by the detonation of high explosive charges.The modelling and analysis was carried out using ANSYS AUTODYN solver.The accuracy of the modelling and its parameters is numerically verified against published experimental results of blast load tests on reinforced concrete slabs.The model was capable of simulating the observed damage and displacement with reasonable accuracy.The verified model is then used for extensive parametric study to examine the effect of different design parameters on the performance of reinforced concrete walls under the effect of blast loads.The design parameters considered in this study include the effect of concrete compressive strength of RC wall, the wall thickness, the reinforcement amount and details, and reflected peak pressure.The wall performance was evaluated considering maximum displacement, extent of damage and energy absorbed within the wall through damage.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
