@All.

It is so simple, at the centre of the beam bending force is maximum while as shear force is minimal that is why spacing of stirrups or shear reinforcement is increased because less spacing would increase no of stirrups which is not required and near the ends, the shear force is maximum hence spacing of stirrups is kept less to save it from shear failure or torsion. So, the right answer is D.

All are misunderstanding the Question.

"Spacing of stirrups is increased at the centre".

In other words, the Gaps or Distance between the stirrups are kept larger at the Centre.

The correct answer is D, Spacing of stirrups increase in the centre, spacing increase the gap, not the placement of striuup increase.

Spacing is Maximum at the centre. So the answer is D.

Shear force is maximum at supports so we decrease spacing near the supports. And minimum in the center of beam hence we can increase spacing of stirrups.

Also trick in the beam where Bending moment is maximum shear force is minimum.

And where bending moment is minimum shear force is maximum.

According to me, the correct Answer is C.

At the centre the spacing is more than at the edges. But practically we keep same spacing throughout. So as per question D is correct option.

Spacing is more at centre an less at end. Read question carefully.

@All.

Thanks a lot.

Stirrups are for resisting shear & torsion thus answer is D.
