- The design of gantry girder is explained in this video step by step with full procedure.
But before watching this part, please watch the 1st part of gantry girder for better understanding.
You can watch 1st part from this link;
• Design of Gantry Girde...
Sir h1 is the centroidal distance. But considered it as difference between CG of I section and NA depth. I.e. h=364.21-300 = 64.21mm. Can u please clarify it sir
Sir ek dout hai....
Jb do trolley place kiye the,to
R.... C ke bich ka distance kya tha... Clear nai hua...
How do you get value 64.21 in step 5? You said you get it by subtracting 235.79 from CG of I-section but it is not 300 you got it as 364.21. The ans should be 128.42 right??
Step 1 me jo impact allowance hai, vo EOT and hand operated cranes ko different hota hai na.. agar hum ko kounsi operated crane ki specify nahi kiya thn which type of crane should we imagine?
Jo ek sem mein nhi samjha, voh apne ek lecture mein samjhaya..
Good one Sir.. Aap PCCOE mein ajaiye dhapekar ko boycott karke..
Sir, why are you using ISMB600 and ISMC300? Because there are many designation like ISWB 550.Please sir clear my doubt this point..
Sir aapne plastic section module. Nikala h tb tw ku consider kra h wha 117.44 ki jagh (300-190.16+13 .6) chaie na plzz sir reply
Hello sir. I am facing problem in finding bending moment in a question. I request you to help me with this.
Design a simply supported gantry girder to carry an electric overhead travelling crane for following data
Crane capacity 320 kN
Weight of crane and crab 300 kN
Weight of crane 200 kN
Max approach of crane hook 1.20 m
Distance b/w c/c of wheels 3.20 m
Distance b/w c/c of gantries 16 m
Span of gantriy girder 4 m
Weight of rails 300 N/m
Height of rails 75 mm
Yield stress of steel 280 MPa
Hello sir, while calculating the surge load per wheel why did you take 4 wheels.. it should be 2 right?!
Two wheels on both sides of Girder.
Boss Zp ki value kidhar se li? Steel book mein tok Zx and Zy dia hua hai
Hi Sir , In My Example all values are same but the span of gantry girder is 5m . Than for calculation B.M. in step (2) . Distance calculated as per concept is greater than 0.65L than what should i do ??
Please help sir
in step 2
you wrote self wt. of rail section = 0.300 kn/m. (please clarify why you did this)
In Breaking force
you took static wheel load = 160.40 but i think it should be taken 200.50 as we use factored load
please reply me soon
please reply me soon

i needed very much
please try to understand!!
From the calculations of Iyy, lzz i don't understand anything ☹️☹️☹️
In step-4 the value of Zp req.=3820cm3 and for ISMB Zp=3510.63cm3. so how can we take the section of lesser Zp than the req. One??? Plzz explain
At 21:14 tumne kaha tha ki jo section hum assume karengai uska Zp zada hona chaiye Zp required se.
Lekin jo tumne section liya hai ISMB 600 uska Zp tou kam hai Zp req. se.
Tou iske baare mai thoda Clear karoge?
This is very much helpful for me
If we are constrained to make section out of plates what will be the changes ?
Bhai best way se smjhate ho and best hai apka channel
Bt yeh ads bhut gusaa aata hai...
Itna acha flow chll rha hota hai
Mushkil topics hai smjh aana shurru hota hai ke ads aa jati hai...
Bhai please 30 min ke video me
5,6 ads sara flow kharb ho jata hai...!!
37:00 me 9th check me 2.43d by tw kaha se liya sir .
Book me use kiya h but source nhi mil rha.
Or KL by r use kar skte h kya.
Brother how did you select section as the value of zp you have chosen is quite different
Sir aapne section (ISMC 300 & ISMB 600) kaise select kra BOZ plastic modulus se value kafi different h nearby bhi bhi h??
great Videos.But could you elaborate on what corrections should be applied if any of the final checks do not follow?
Sir jo deflection check lagaya he usme W ki value konsi lenge...
Thank you sir. Your explanation is very good and helpful. But as gantry girder is a laterally unsupported beam, so the formula for moment capacity shouldn't be the one you have used. There's one another formula for calculation of moment capacity in IS 800. Isn't it?
Look, there are two conditions given in IS:800, 1st is on page 53 (that we have used) says that, if design s.f. is less than 0.6xVd, then Md shall be used according cl.8.2.1.2.
Now the condition which you are talking about is on page 69 & 70, which says that if there is high value of s.f. which exceeds 0.6xVd, then only we should have to considered Md as per cl.9.2.2.
Ok
@@Technicalcivil sir pls tell how 243.39 came pls tell me sir tomorrow is my exam of dss2😟
From step 6 , input the values and complete the design, and with respect to this design, detailed drawing has to be revised.
You are a great sir
But sir i hve one question
Isme jo step 3 me
Longitudinal braking force hai usme wheel load 160.40 kaha se aaya
Ye wheel load humne step 1 me calculate kar rakha hai.
Ohkk sir👍👍

Please explain me how did u get 7.6? @33:54. I would be expecting your reply since I have exams in the coming days
@@Redmi-gi9nl isn't it the thickness of the web in channel section
Please can you tell me more about assuming of self weight of gantry girder
How to design column and column base for gantry??????
I need drawings for this design , I have no internal marks ,I have to get 49 so please tell me about drawings it's very important ,which drawing should I draw on drawing board?I don't have any drawings example so plz help me
Sir can u plz tell me about drawings ,how to draw drawings plan and elevation ?
Hii sir, how u take wheels on girder, consideration of wheels, I'm unable to understand
Which book you are referring sir ?
Or ha sir difelection check agar satisfy nahi hota he to kya karna he...
In the question the self weight of rail section is given as 300kN but in step 2 you have taken 0.3kN/m how is it possible.
plz reply
Sir how can I design plate gantry girder & what's web and flange sizes?
Can u plz clarify about the value "117.44" in plastic section modulus above equal area axis?
The like is to remind you of how anxiously you studied this subject once.
Konsi book se kraya h bhai jldi batao...
SIR in step 6 plastic section modulus
below the equal area axis and above the equal area axis calulation not understanding
can u send me formula for this
In question the weight of rail section already given 300 KN then in solution it's equal to 0.3 KN/m and then summation equal to 1.9...????How??
Thats because the self weight of gantry has been assumed as 1.6 which was added with the weight of rail.
1.6+0.3=1.9KN/m.
Hope it helped.
Plz.. tell me how u divided 1.75-1.75 in 2nd step for mxm bm. Plz reply as soon as possible i m waiting.!
b=3.5(given) and by dividing 3.5/2 you will get 1.75
required Zpz = 3.82 × 10^6 mm^3
Yeh value kaha se aya bhi ?
How did you selected ISMB 600 and ISMC 300 ??
in 1st step ,maximum wheel load calclulate krne k bad use factored load me convert krna h n..? 240*1.5
Ya even I have same question...
Wheel load 250 ko 1.5 se multiply karney ka tha...
if ishb 400 @82.2 kg section and ismc 300 section dp ??
Didn't understand the 2 step diagram can som1 tell me plz.....
Can you pls explain me how to select a section according to zp
Hey brother why didn't u consider the cover plate in ur drawing?
Plz make 2nd example of gantry girder as soon as possible
in calculating wheel load for impact you increased actual value by 25% while in calculating surge load for impact you calculated 10% of actual value and not increasing it by 10%.....can you explain why ?
AS PER IS 875
Sir step 5 in calculation of Izz the value of (Ig) kaha se aayi ?
No doubt thank you sirrrrr wonderfull teaching
Is it necessary to take channel section..If I section satisfy the condition
No, its not necessary.
Sir, how can u mark the N. A. Z-Z
please Explain it sir
tq sir its usefull for my examination
Sir jo book aap use kar rahe hai uska nam kya hai?
Bhai ye ISMB 600 AND ISMC 300 is code me kaha pe diya hai .....????
Plzz tell me..
Is 800 page 138
bro 7th step AV ke keya hai uski value keya ha
8th step(fbd) ke keya value hai
9th step (tw and fcd) ke value keya hai
10th step (VA) ke keya value hai
apne bahut acha samjaeya but ye 7th, 8th, 9th, 10th step me je doubt hai please jeh samja de ap thanks
Please explain me how did u get 7.6? @33:54
Bro, ur solution is different from nptel lecture solution.
Which one to consider.
Plz tell
Brother, can u make 1video regarding the check
Bhut confusion ho rhi h
In all the checks
I m havinng problem in choosing value.

Kindly send me the solution of check
My exams are coming plz plz
Love you bro I learn much from you
Sir didn't understand any thing , static wheel load kha se le rhe ho ,kya kr rhe ho,kuch smj nhi aaya😢😢
in second step max BM (-2.85*2.875*2.875/2) how?
plz explain me
Its udl..
Calculate like udl ..
sir i didnt understand the 2 step diagram can someone tell me
Design load on each wheel
Increase wt by 25% i.e. 0.25 for impact
(IS 875,Part 2,cl 6.1 P. 15)
But you taken
1.25*160.40 ( load on each wheel)
How?? Explain once.
Very fine detailing
Sir hum Zy kyuu find out kare in step 5
Crane Girder span question me nahi di ho toh kese design karte he?
Thanku sir for uploading video of this topic
How to select the section of gantry girder?
if ismb 600 is selected then checks will not satisfy...so pls change the section with iswb 600 ...
Kya esi values se chart ke upar diagram dhalke dhikavoo plssss
Sir, how to assume self wt. Of gantry girder =1.6KN/m
You can assume it under some reasionable values. Like you can also assume it as 2kN/m or 2.5 or 3...but assuming it too much large or too much small is not advisible.
@@Technicalcivil ok sir thank you 😘😘
Bhai jo apne 1.5 k sath multiply kiya hai factor laod nikalne k liye vo apne 1.5 hi kyu liya
That 1.5 is given in IS code
Sir, how to design stiffener?
Please make a video.
In 10 step qw = there na in that VA means which value
160.40 static wheel load kaha se aaya?
Step no.6 check for moment capacity me 'Mu' kahase use hoga??
Max bm calculated In step 2 which is 681.85 kN
Max BM calculated In step 2 which is 681.85 kN

Good Explanation
U didn't explain about getting the neutral axis depth...
big big big big big THANK YOU sir.
great explanation .
Thank you for your teaching sir
Thank you bro it's really helpful
why have u not done checking
A big thanks from my 💓
sir base wheel ka keshe find karna he
Please make a video on portal frames of fixed N hinged base support
Sir step 10 me .7s ,s kya h
how u determine the distance between a and b
Its given in question as wheel base.
will you explain step no-5 in detail its little confusing please
Tell me whats your confusion, we will try to resolve it.
Ig+ah2 me h ki value kese leni hai?
Sir.. iska part 3 banaiye sir step no 6 to 11 kaise value put karna Hain samajh me nahi aa raha..
Can you explain how to calculate Mdy in fst check.
Thank you
And this video is very helpful in understanding the Gantry girder and it's design clearly.
y bar kase find out Karen channel or I section connection main???
Bhai bta de yaar
y bar = (a1y1+a2y2) / (a1+a2)
Further i have discussed in videos gantry girder part 1&2. Please watch it completly without any skip. And if again you have trouble, then you are free to comment me. Ok. Have a gud luck
please make video on truss girder bridge
Jo aapdne design of welded connectt and support bracket connection need not be design kidhu hoy to ketla step karvana
Then you have to solve upto 9th step.
can you upload railway bridge design like stinger , cross beams
35:00 previously the value was 243.39 and now you have taken 117.44 ... How?
Phr sy chk karo....plz
Pls tell me how 243.39 came out
@@CR-zq6cu
See from @22:39, You'll understand
@@senkuishigami5163 i got it👍
@@CR-zq6cu
also the values 117.43 and 89. are wrong..His calculation went wrong
BTW do you have notes for Plate Girder?
Sir iski PDF milegi k ? 🙏🙏🙏🙏
8:50 , Bhai 25% boleto 0.25 hy then why did u multiply with 1.25 ??
Reply diyo bhai ...
Agar aap 160.40 + (160.40x0.25) karonge aur 1.25 x 160.40 karonge to answer same hi ayenga.
Because dono cheeze same hai bus method thode alag hai.
Bhai uska kuch formula hy kya ?
No
Fir 160.40 two times kyu daala ?
