Is 459-1978 recommends to provide certain minimum steel in a RCC beam

[A]. to ensure compression failure
[B]. to avoid rupture of steel in case a flexural failure occurs
[C]. to hold the stirrup steel in position
[D]. to provide enough ductility to the beam

Answer: Option B

Concrete is weak in tension, so that concrete is reinforced to resist tension force acting on it.

Also to avoid sudden failure because the difference between steel and concrete tension strength. When over load -over stress the cracks appears will be warning.

I think it is to provide enough ductility to the beam. The language of option B is not suitable for answer.

Deepthi said: (Dec 16, 2014)  
Ductility might be suitable option as per is 13920.

Paras Nayyar said: (May 23, 2016)  
According to me option D is the correct answer.

Karthik said: (Sep 12, 2016)  
I think option B is correct because steel is mainly provided to give flexural strength to the concrete.

Rahul said: (Nov 18, 2016)  
Yes, D is the answer.

IS 456-2000 Recommends providing certain minimum steel in a RCC beam.

Answer : to provide enough ductility to the beam.

Asaithambi said: (Feb 9, 2017)  
Sometimes minimum steels are provided beam first ductility and second time of rupture and flexure failure.

Shashi said: (Sep 25, 2017)  
I think the answer is D.

Roy said: (Jan 22, 2018)  
Can you please tell me the clause no Aaron?

Ronak Gupta said: (Feb 5, 2018)  
Yes, the answer is D.

Niru said: (Dec 26, 2018)  
Yes, the answer is D. I agree.

Hethu said: (Jan 17, 2019)  
Rupture of steel is desirable because it gives prior warning before sudden failure so option B can not be answer. Option D is correct answer.

Shankar said: (Jan 25, 2019)  
Minimum tension steel reinforcement prevent sudden failure.

Niladri Roy said: (Feb 29, 2020)  
The correct answer is to provide enough ductility to the beam.
