Answer should be B as shear force is minimum at the center. Any drawing also suggests that if you google it.

Answer is B decrease towards the centre. Shear force is maximum at the end and also provide ductility. Which give resistance against earthquake.

Louis said: (Jul 25, 2017)  
The Answer is D. Because for a simply supported UDL beam shear force is zero at centre and max at ends.

Sukanta said: (Sep 15, 2017)  

If shear force is zero at the centre then why spacing of stirrups will increased at centre.

Rh said: (Sep 22, 2017)  
C/c space is increasing means there are less stirrups in the centre as compared to ends.

First, try to understand the question D is the right answer.

Skn said: (Sep 29, 2017)  

The Correct answer is D.

Suniltherockmeena said: (Jan 17, 2018)  
Correct answer should be D as stirrup are required less spaced at ends and more spaced towards center because shear force is maximum at supports and zero at center so where no shear force acting, practically no shear stirrup required.

Kamlesh said: (Jan 21, 2018)  
Answer is D as shear force is max near support so stirrups are closely spaced near support and spacing goes on increasing as we move towards the centre of the beam.

Kamlesh said: (Jan 21, 2018)  
Spacing increases at centre not the stirrups.

Ali Raza Khan said: (Feb 14, 2018)  
It's spacing of stirrups and not a number of stirrups. D is the correct answer. Increasing spacing means lesser number of stirrups in a unit length.

Utsav said: (Jan 27, 2019)  
Stirrups are for resisting shear & torsion thus answer is D.

Thanks a lot.

Abhinandan said: (Dec 11, 2019)  
Spacing is more at centre an less at end. Read question carefully.

Abubakar said: (Feb 23, 2020)  
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.

Hardik said: (Jul 26, 2020)  
According to me, the correct Answer is C.

Tauhid said: (Oct 13, 2020)  
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.

Yubraj Joshi said: (Oct 15, 2020)  
Spacing is Maximum at the centre. So the answer is D.

Ayan Jyoti Deuri said: (Apr 24, 2021)  
The correct answer is D, Spacing of stirrups increase in the centre, spacing increase the gap, not the placement of striuup increase.

Johny Sins said: (May 25, 2021)  

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.
