The main reinforcement of a RC slab consists of 10 mm bars at 10 cm spacing if it is desired to replace 10 mm bars by 12 mm bars, then the spacing of 12 mm bars should be
Answer:
A) 12 cm
B) 14 cm
C) 14.40 cm
D) 16 cm
Explanation:
Option (c) is correct The horizontal distance between parallel main reinforcement bars shall not be more than three times the effective depth of solid slab or 300 mm whichever is smaller. The total reinforcement in the slab should remain same. By replacing 10mm bars by 12 mm bars, the spacing will increase as

The total reinforcement in the slab should remain same. By replacing 10mm bars by 12 mm bars, the spacing will increase as
A) Maximum longitudinal reinforcement in an axillary loaded short column is 6% of gross sectional area
B) Columns with circular section are provided with transverse reinforcement of helical type only
C) Spacing of lateral ties cannot be more than 16 times the diameter of the tie bar
D) Longitudinal reinforcement bar need not be in contact with lateral ties
A) Decreases with decrease in stirrup spacing
B) Decreases with increase in longitudinal bars
C) Does not depend upon stirrup and longitudinal steels
D) Increases with the increase in stirrup and longitudinal steels
