Abstract
The performance of composite structures employing reactive powder concrete (RPC) has received limited attention.The special components of RPC may affect interface response, crack distribution, and shear transfer mechanisms.The current study investigates the experimental behavior of simply supported composite decks that consisted of steel sections and RPC under axial loading.The influence of parameters such as the thickness of the concrete deck, the number of studs, and the contribution of thread bolts and angle sections as shear connectors was investigated.It was found that the value of the ultimate load increases as the thickness of the RPC deck increases.On the other hand, a reduction in the relative end slip was noticed with the increase of deck thickness.The contribution of increasing the number of studs in enhancing the behavior of composite structures was clear.Moreover, using an insufficient number of shear connectors caused the development of longitudinal cracks along the top surface of the deck.Results showed that employing transversal channels as shear connectors had a positive impact on reducing end slip and preventing longitudinal cracks.On the other hand, using threaded bolts may cause local slip around the bolts.

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
