Which reinforcement is placed parallel with beams and stringers?

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

Answer: (D)

Reinforcement in a bridge deck is described by its function and direction. The bars that run along the length of the structure, staying parallel with the beams and stringers, are the secondary reinforcement. Their job is to help distribute loads, keep the main tension bars in place, and provide crack control and redundancy across the deck. They aren’t the main tension reinforcement—that role belongs to the primary bars, which carry the primary bending stresses in the member. The terms positive and negative moment tension describe where tension occurs due to bending, not a separate type of reinforcement. So, the longitudinal reinforcement running along the length is considered secondary reinforcement.
