This is very important question.
Thanks for simple explanation of this question and for make this vidio leacture..
You're welcome 😊
THANK YOU MAM ITS BECAUSE OF YOUR THIS VIDEO I WAS ABLE TO UNDERSTAND DISTRIBUTION OF LOADS FOR WELD ( THAT MOMENT CALCULATION SPECIALLY)... EARLIER I WAS DOING IT ALL WRONG....THANKYOU ONCE AGAIN MAM
I'm glad you liked it....Stay tuned :)
It was really helpfull lecture. Thank you.
Most welcome!
Ma'am very nice explained... Thanks for you.. I love it your way of presentation is so good ma'am..we can easily understand... 💞💞
Thank you 😊
Q. Two plates of 12 mm thickness are jointogether. Design a suitable filled welled to transmit a tensile fore of 275 KN (Shop weld)
your lectures are amazing, please provide a pdf of the session, as it will be really helpful.
I'll try to create a forum to share PDFs
Thank you mam for this lecture very helpful
You're welcome 😊
Kya baat h yaar adbhut treeke se samjhaya h
Thank you 😊
Mam while calculating Smin we have minimum thickness 8mm(thikness of bar) but u took 12mm as minimum thickness which is the thickness of gusset plate
While selecting the minimum size of the weld we consider the thicker plate. Hence, the gusset plate thickness of 12 mm has been considered.
Amazing class 🙂
Thank you 😊
Thanks for the problem. I have a question for you. Shouldn't it have been "the design strength of the WELD" rather than "the design strength of the JOINT". Because the design strength of the joint would be the minimum of the design strength of the weld and the yield strength of the plate. What would you say?
Yes, it’s right that the design strength of the entire joint will include the failure mechanism of the plate as well. However, at this level the question demands the design strength of the weld only.
In the field the design strength will be calculated by considering the failure mechanisms of both the connection and the plate.
Very useful lectures. Appreciate if you could explain column beam weld connection (I Sections) involving vertical loads. Looking forward for your help. Thanks
Noted
Where can we get this steel table
In àny bookshop selling civil engineering books and study material.
In this case how will we provide end returns as the length of parallel welds is unequal ?
Great mam. Its ur bad luck that u r not in ur college ❤❤❤❤❤
Thanks a lot
Mam is it necessary to provide the weld in such a way that in the unequal length ...What will happen if you have provide the full length of weld in top and bottom ...But in practically i have seen all the welds in uniform length at top and bottom irrespective of the steel section ... Please clarify my doubt mam
You can revisit the moment calculations to determine the necessity of the length of the weld.
The distribution of weld length depends on the section being used as the location of the centre of gravity of the section will influence the load distribution
Practically equal welds may be provided because of a few reasons
1. Inadequate length provided
2. Weld has not been technically designed and is provided by the welder
3. The weld length provided on the upper portion is longer than that actually required there. Eg. 300mm is required at the upper edge of the angle and 500mm at the lower edge (near root), instead 500mm is provided on both the edges. - this will increase the cost slightly but increases workability
@@civilengg.withakriti2556 ...Mam can you please tell me which text books you have referred for this steel design
Please refer the first slide and description box of the video.
Steel structure design by SK Duggal has been referred for the video
madam, please make a session on the design of X-Bracings, both for HXB and VXB.
Mam can u do videos on eccentric loading also plz
How can we know it is rolled section it is confusing because in some examples maximum size of weld calculated as s max = Thickness - 1.5
The sections used directly from the steel table are rolled steel sections.. The ones made up by using plates are built up sections.
Sometimes we join rolled sections as well to make built up sections
Very nice man.but only doubt is that in question fe410 steel grade is given and u taken fy 250.so how to decide aur calculate this please explain
Check IS 800, for Fe415, fy value is 250
Mam y kafi jyada typical ta bt I understand 🙂 mam exam m in sbi big question ko solve kaisa kranga in 2.5 hours.....🥺
Practice is the key...
@@civilengg.withakriti2556 ok ma'am
Mam i love you so much
Thanks🙏🏽
Mam ❤️ appna angle ko truss member q bola ...🤔
Angle ko truss banane k liye use kiya jata hai... Isliye isko truss member bola jata hai
@@civilengg.withakriti2556 thank you mam🙏
Nice video pehechana mujhe???
Thank You :)
Apse zyada complicated koi nahi samjhata 😅
I hope you find a tutor you are able to understand 😊
