42.
In a singly reinforced beam
compression is borne entirely by concrete
steel possesses initial stresses when em-beded in concrete
plane sections transverse to the centre line of the beam before bending remain plane after bending
elastic modulii for concrete and steel have different values within the limits of deformation of the beam
none of these.
Answer: Option

No answer description is available. Let's discuss.

Only C is correct.

In option A, compression is not born entirely by concrete, there's an external load and moment which also contribute to it.

Option A is also correct as this is singly reinforced stirrups are provided in case of doubly reinforced beam along with compression reinforcement.

Option [A] is the correct answer.

As in singly reinforced beam, only the design of steel is done for tension reinforcement. Anchor reinforcement is not designed but just provides a hanger bar for shear reinforcement. And all the options are based on elastic theory.

No, A is not correct because we provide 2 bars in top also which also carries some compression and also bent bars also shares some compression force.

There is no compression steel in the singly reinforced beam. I think A also correct.

@Tinku option A is not correct. Compression steel is provided in beams to increase the ductility.

Kindly give the correct answer with an explanation.

Tinku said:   9 years ago
I think Option A is also correct.
