Nonlinear Shear Buckling Parametric Finite-Element Analysis of Corrugated Steel Webs
Bibliographic record
Abstract
The corrugated steel web of prestressed concrete box-girder with corrugated steel webs is in pure shear stress state. The shear-resistant capacity of the corrugated steel web is not determined by the shear strength of steel web, but controlled by the shear buckling strength of steel web. The shear buckling mode and ultimate shear capacity of corrugated steel webs are analyzed by nonlinear finite elements method. The corrugated webs are simulated by 8-node structure shell element. The simulation was done for the defect of corrugated steel web with uniform imperfections mode method, and the defects were included in the material nonlinearity and geometric nonlinearity. On this basis, the influences of corrugation configuration, the overall profile dimensions and steel thickness of corrugated webs on ultimate shear buckling load and buckling mode are investigated.

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.
