Ratio of Maximum and Minimum Percentage of Longitudinal Reinforcement in a Column
Maximum and minimum percentages of longitudinal reinforcement that can be provided in a column depend on several factors such as the size of the column, the load it carries, and the type of reinforcement used. The ratio of the maximum and minimum percentage of longitudinal reinforcement in a column is given by:
Ratio = Maximum Percentage / Minimum Percentage
For a rectangular column, the maximum percentage of longitudinal reinforcement is limited by the spacing of reinforcing bars, which should not exceed three times the diameter of the bars. The minimum percentage of longitudinal reinforcement is limited by the requirement of providing adequate strength to the column.
The ACI code specifies the following limits on the maximum and minimum percentages of longitudinal reinforcement in a column:
- Maximum Percentage: The maximum percentage of longitudinal reinforcement in a column should not exceed 6% of the gross cross-sectional area.
- Minimum Percentage: The minimum percentage of longitudinal reinforcement in a column should not be less than 0.8% of the gross cross-sectional area.
Therefore, the ratio of the maximum and minimum percentages of longitudinal reinforcement in a column is:
Ratio = Maximum Percentage / Minimum Percentage = 6% / 0.8% = 7.5
Hence, the correct answer is option B (7.5).
