Question

Match List-I with List-II and select the correct answer using the codes given below the list:

A. Minimum percentage of tension reinforcement of RC beam

B. Minimum percentage of shear reinforcement of RC beam

C. Maximum allowable percentage of tension reinforcement of RC beam

D. Maximum allowable percentage of compression reinforcement of RC beam

List-II

1. 4

2. $\frac{85}{f_y}$

3. $\frac{40S_v}{f_{y}d}$

Codes:
A B C D

• A. 2 1 3 1
• B. 2 3 1 1
• C. 1 3 1 2
• D. 3 2 1 1

Answer 1

The correct option is B 2 3 1 1

(i) Minimum area of tension reinforcement

$\frac{0.85}{f_y}\left(bd\right)or\frac{85}{f_y}\%$.

(ii) Maximum tension or compression
reinforcement= 0.04 bD or 4% of gross area.
Minimum shear reinforcement $\frac{A_{sv}}{b{S}_v}\ge \frac{0.4}{0.87f_y}$

as per IS : 456-2000
shear reinforcement is IS : 456-1978 was

given as $\frac{A_{sv}}{b{S}_v}\ge \frac{0.4}{f_y}$

$\therefore$ The percentage reinforcement is

$\frac{A_{sv}}{bd}=\frac{40S_v}{f_{y}d}$
