Shear analysis and static load test of single-box and multicell composite girders with corrugated steel webs: a case study
Bibliographic record
Abstract
The shear design of a corrugated steel web box girder is important for structural reliability. Presently, corrugated steel webs bear all the shear forces, and the top and bottom concrete plates bear no shear force. Each steel web has equal force. This design is conservative and uneconomical and may sometimes be unsafe. The shear ratio and transfer efficiency of each corrugated steel web are investigated in this study through numerical analysis. Then, the distribution of shear stress in corrugated steel webs is verified through a static load test. Results show that the shear is shared by the top and bottom concrete plates and corrugated steel webs. The shear ratio presents a close relation with boundary, loading, and section position. The influence of a transverse diaphragm on the shear ratio is minimal, and this influence demonstrates a certain effect only on the steel webs located at the area of the transverse diaphragm.

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.
