The minimum longitudinal steel percentage permitted in reinforced concrete columns per ACI 318 is:
  • 1%✔️
  • 2%
  • 4%
  • 8%
Correct Answer Explanation
ACI 318 specifies the minimum longitudinal reinforcement ratio for columns as \(\rho_{min} = 0.01\) (1%) and the maximum as \(\rho_{max} = 0.08\) (8%) of the gross cross-sectional area \(A_g\).
