railway RRB JE (CBT I + CBT II) Mock Test 2024 Reinforced Concrete Structures Bond, Anchorage and Development Length
In the steel reinforcement calculation for RCC, the additional length for two 45° bent – ups in reinforcing bars is:
1
0.42 times the length of distance between the centre of the upper and lower arms of the bent up bars
2
0.84 times the total depth of beam or slab minus bottom and top cover
3
Sin 45° times the length of distance between the centre of the upper and lower arms of the bent up bars
4
(1 – sin45°) times the total depth of beam or slab minus bottom and top cover
