Q1:

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

ANS:B - to avoid rupture of steel in case a flexural failure occurs

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.
