20.

Pick up the correct statement regarding columns.

 [A]. The cross sectional area of longitudinal reinforcement, should not be less than 0.8% nor more than 4% of its gross sectional area [B]. The minimum of longitudinal bars provided in rectangular and circular columns are 4 and 6 respectively [C]. In helically reinforced column, the minimum number of longitudinal reinforcement should be six [D]. If the effective length of a column is less than three times its lateral dimension, it is generally called a pedestal [E]. All the above.
