Which reinforcement is placed transversely across the deck?

Which reinforcement is placed transversely across the deck?

• A. Secondary reinforcement
• B. Positive Moment Tension
• C. Primary reinforcement
• D. Negative Moment Tension

Answer: (C)

In a deck slab, reinforcement is organized into two roles: the main structural reinforcing that carries the primary tensile forces, and the secondary reinforcement that helps distribute stresses and control cracking. The bars placed across the deck, spanning from one side to the other, form the main tensile path for loads that act across the width of the deck and between supports. Because they carry the principal bending-induced tension in the deck, these transverse bars are treated as the primary reinforcement. The terms positive moment tension and negative moment tension describe where bending moments cause tension in the member, not the type or orientation of reinforcement, and secondary reinforcement is typically used to tie and distribute stresses rather than carry the main load.
