Question

Maximum longitudinal reinforcement in columns shall not exceed ___

• A. 6% of effective sectional area
• B. 4% of gross sectional area
• C. 6% of gross sectional area
• D. 4% of effective area

Hint:

When designing columns, always refer to design codes to ensure reinforcement limits are not exceeded for safety.

Answer 1

The Correct Option is C

The maximum longitudinal reinforcement in a column is limited to prevent over-reinforcement, which could lead to brittle failure. According to design codes, the maximum allowable reinforcement is 6% of the gross sectional area, which includes both the concrete and reinforcement areas. Hence, the correct answer is 6% of gross sectional area.
