Explanation:

No answer description available for this question.

d/t<85 no stiffener.

d/t 85-200 vertical stiffener.

d/t 200-250 vertical stiffener and 1 horizontal stiffener.

Rishi R said: (Feb 23, 2016)  
d/t 250-400 vertical stiffener + 1st horizontal stiffener + 2nd horizontal stiffener.

Ramen said: (Aug 10, 2016)  
So why option d is correct?

Guru Prasad Mahapatra said: (Dec 14, 2016)  
According to me, option B is the correct answer.

Amrit Raj Negi said: (Jan 29, 2017)  
d/t < 85-200 for vertical stiffener.

I think the answer is A.

K K Baba said: (Mar 15, 2017)  
d/t< 85-200 for vertical stiffener.

So, the answer is D/85 means.

Rohit Negi said: (Aug 1, 2017)  
Anwser b is correct.

Suman Rai said: (Sep 23, 2017)  
Yes, A is the right answer.

Deepak said: (Nov 19, 2017)  
According to the question, The answer will be min. 85 and max 200 for vertical stiffness. So I think answer A is correct.

Naveen Kallan said: (Dec 1, 2017)  
D/t should be 85 to 200.

Min value is D/200.

Ritu said: (Dec 17, 2017)  
Option D is correct.

Satyavan Saini said: (Dec 20, 2017)  
Because in question giving no less than, so option A is not correct.

Pankaj Chaudhary said: (Jan 7, 2018)  
A is correct.

No stiffeners are provided if web is less than d/85.

Vertical stiffeners are provided if web is more than d/85 but less than d/200.

Vertical +1horizontal stiffeners are provided if web is more than d/200 but less than d/250 (in this case this 1 horizontal stiffener is usuall place at 2/5th of the depth of neutral axis from the compression flange).

Vertical +2 horizontal stiffeners are provided if web is more than d/250 (in this case this 2nd horizontal stiffener is usuall place at neutral axis).

Garry said: (Jan 19, 2018)  
The correct answer is option B.

Prasenjit said: (Jan 26, 2018)  
According to me, A is correct.

Simi said: (Jul 11, 2018)  
Yes, A is the right answer.

Sam said: (Sep 12, 2018)  
Option B is the right answer.

Satyamev said: (Sep 22, 2018)  
Minimum D/200 max is D/85.

If the thickness exceeds d/85 then no stiffener required because. There is enough strength to carry the load as the thickness is more.

So, the minimum d/200.

V.V.Savaliya said: (Sep 30, 2018)  
Absolutely right, Thanks @Satyamev.

Nilraj said: (Dec 9, 2018)  
Correct @Satyamev.

Mayur Padekar said: (Apr 8, 2019)  
A is the correct answer.

Anomie said: (May 27, 2019)  
Yes, right @Pankaj.

Pankaj said: (May 27, 2019)  
B is correct.

No stiffeners are provided if the web is more than d/85.

Vertical stiffeners are provided if the web is less than d/85 but more than d/200.

Vertical +1horizontal stiffeners are provided if the web is more than d/200 but less than d/250 (in this case this 1 horizontal stiffener is usual to place at 2/5th of the depth of neutral axis from the compression flange).

Vertical +2 horizontal stiffeners are provided if the web is less than d/250 (in this case this 2nd horizontal stiffener is usually placed at neutral axis).

Partha said: (Aug 18, 2019)  
The answer is fine if you consider the following case as vertical stiffened web plate.

Here min web thickness is concerned so d/250 is the correct answer.

Vertical +1horizontal stiffeners are provided if the web is more than d/200 but less than d/250 (in this case this 1 horizontal stiffener is usual to place at 2/5th of the depth of neutral axis from the compression flange).

It's 180 or section will fail in shear before bucking.

Sanku said: (Oct 11, 2020)  
The right answer should be option A.
