@structtutor: Why are these studs hidden in the deck? Watch the two marks at the steel–concrete interface. With no shear transfer, the marks slide past each other. With full composite action, they move together. The same load then produces less deflection. The animation compares two elastic idealizations for a 6 m simply supported beam: free slip and full interaction. The zero slip in the connected model is an idealization. Deflection uses a common scale in both beams and interface slip is magnified separately.
