Rupture is a failure in which a material fails abruptly as we know steel possesses a certain ductility and undergoes some deflection and gives a warning before failure so abrupt failure is not possible in RCC structure.

So, the answer D will be correct.

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.

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.

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

Answer : to provide enough ductility to the beam.

Option D is correct.

To provide enough ductility so that beam can't fail in compression (to avoid sudden failure).

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

Asaithambi said:   9 years ago
Sometimes minimum steels are provided beam first ductility and second time of rupture and flexure failure.

Karthik said:   9 years ago
I think option B is correct because steel is mainly provided to give flexural strength to the concrete.

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

The correct answer is to provide enough ductility to the beam.
