lf inclination of main rafter to horizontal is not given then use the formula:
tanx=height of truss÷half of span of truss
If not we can assume as 30degree
Tan x OR Tan inverse x??
Tan inverse of height of truss by half span
Thank you sir ❤
better explain by showing code book and steel tables
Sir ur voice is mich low not audible and video is very useful to me
Sorry for inconvenience. I will keep it in mind.
Nice but sound low
Thanks for your suggestion.
I will correct it from next time.
@@Civillearningonline yeah.. Sure..
But i got this problem..
Really.. Thank you..
@@supriyaskitchen44 kya yaar bohot kam sound hai meko inta bhi smajh nhi aya video kyu banate h ye log
Nice video.
But purlin is continuous beam therefore bending movement formula is different
The design of purlin is totally as per the is code we are not using any formula by our self.
Where in code shape factor for Zpy/Zey is given here only shape factor is given for Zpz/Zez
how to take Zyy from the page 139 please explain i am unable to understand
Perhaps my video on Design of channel section purlin is going to help you. Check out the link in description or visit playlist.
Zyy has to be taken from steel tables and it has to be multiplied with shape factor 1.125 to 1.14
Sir I want know in the deflection due to load formula how the I value 1540×10^4 came
It's taken from steel table. ISHB 150.
It's the value of moment of inertia. You will find it in steel table.
I value is Ixx from steel table
Sir, what is refrence book for this calculation??
S k diggal
You mean limit state design of steel structure ( s.kduggal) 2nd eddition
@@suryakantsahu578 yes
How you got Zyy at 8:30 and what is R1
In channel purlin video of yours there also I got same problem
To learn steel structure, one needs to have a steel table and a code book. The value of Zyy is given in the table. It's standard for each type of section. Please refer to steel table.
If you are from India buy R. Agor's steel table. It's available on Flipkart or Amazon also.

Sir, how can we find or calculate shape factor from the code?
Hello dear,
First of all thanks for your comment.
And how to find shape factor is here in my another video on the design of channel section purlin.
ruclips.net/video/ivejYMH-7I8/видео.html
I had added this video so that there would be no any concepts left. As there are mainly two type of purlin asked in exam i.e. I section and channel section. And method to find shape factor is in the design of channel section purlin.
In the design of channel section purlin you can find the proper use of shape factor from the IS code and the value of shape factor is already given in the code in page 137 and 138 of IS 800.
Let me know if you got my points by replying or liking this reply.
I am always tere to help you guys.
Lots of love.
And Have a nice day.
@@Civillearningonline yes, thank you so much sir ❤..
Sir good morning I plan to construct industrial shed with 5ton capacity eot crane.shed size is 60 x130 feet width and height 25 feet clear height . please give me suggestion for column flange and Web thickness , rafter flange and Web thickness and also purlin size. Thank you sir.
Thanks for your comment.
And the thing is I am still studying that topic.
I will let you know soon.
i thing ur Load claculation unit is wrong (130*1.5*1) N/m . How is unit N/m... plz explained this..
Hello dear,
In the following question we are given the weight of corrugated sheeting as 130N/m2.
I have done (130*1.5*1)N/m because here 1.5 is the factor of safety.And 1 is for per meter length.
So (1/m2 * m =1/m).Hope u understood.
Thanks for your comment.
Step 5 confused sir
Is ac sheet elastic cladding?
Yes, it's can be used as an affordable external cladding for the building.
No what I meant is if the question mentioned AC sheet instead of galvanized ,then what would the permissible deflection be??
Thanks for replying and please reply this too💛
You should check the code on galvanized sheet this is going to be very helpful to you. Here is the link to download the code.
www.iitk.ac.in › test › IS-codesPDF
IS 277 (2003): Galvanized Steel Sheets (Plain and Corrugated)
Sir... Actually u r explanation is superb but, sub titles may hide the solution and important data which we require
You can turn it off. By clicking on the CC button after playing the video.
deflection due to load why wind load not considered???
Deflection due to wind load is considered in the video please watch carefully.
@@Civillearningonline load taken 1.79 kN/m not included 4.05KN/m
Let me check
h1+2r1 se to d alg aa rha hai book me alg aa rha hai?
d=h-2(tf+r1) ye sahi hai
Bohot sara formula mila ye bind karne k liye.
Hlo sir shape factor kaha sa lena h
Check into comment section I have mentioned.
Sir kon sa code book h
Combined he. Sk duggal and bhabikatti.
EI ka value kaha milega
Given rehta he question me.
Bhai live load nhi diya to kya assume kre
Hmm
@@Civillearningonline hmm kya sir kya assume karein? And ye mill bend frame industrial frame ko hi bolte hai kya sir
I have supply 😂😂🤩🤩
Ur comment is of such that I can't even react on it.But i can tell u one thing that "Back is a backbone of engineers". So best of luck to u.
Not audible
Sir while calculating toatl laod parallel to sheeting why you did not add factor wind laod any reason ... you add it in toal laod noraml to sheeting but you did not add it in parallel why
When I was in my college I solved it the same way. I went through 3 books which had length process and time consuming from exam point of view. So, I tried this. You can go for it.
@@Civillearningonline thankyou sooo much sir❤️
Where is code ?😅
You can download it.
Speak up please. You cant teach if you cant talk.
I am extremely sorry for your inconvenience. It is the video when I had just started my channel and at that time i had no idea about the sound. But there are other videos in which sound is good.
And you will find one video on design of channel section purlin too. Those two type of design are mainly important.
@@Civillearningonline sir please reply.. How did you find the shape factor to determine Zpy?
Please reply
hindi me pado udar 1 1lakh leke hindi pada rahe he
Ok

Hello dear,
Inorder to calculate Zpz one need to use formula provide in this video which is as per the code.And then we need to assume b and d in such a way that d is twice of b.And the range of d should be between 110 to 150.And automatically if u take 120 or 150 as d the the value of b becomes 60 and 75 respectively.
And after calculating required Zpz we select a section as per the question whether we r asked I section or channel section.
Keep in mind that the section we select must have Zpz greater than our calculated Zpz of step 3.
I hope u have understood.
Or u can check me video on design of channel section to have deep understanding about purlin design.
Thanks for your sweet comment.
I got it sir
