RCC Structures Design - Engineering

Q1:

The length of lap in tension reinforcement should not be less than the bar diameter x (actual tension / four times the permissible average bond stress) if it is more than

A 18 bar diameters

B 24 bar diameters

C 30 bar diameters

D 36 bar diameters

ANS:C - 30 bar diameters

The length of lap in tension reinforcement should not be less than the product of the bar diameter and the ratio of actual tension to four times the permissible average bond stress if it is more than 30 bar diameters. So, the correct option is: 30 bar diameters.
