at 9:30 why did you used the ultimate strength of plate instead of the ultimate strength of bolt even though you were calculating the bearing strength of "bolt".
In calculating bearing stress we r actually taking the projected area of the bolt on the plate, so we need to take the ultimate tense stress of plate not the bolt
In some books the formula of strength of solid plate is (0.9×Ag×fu/safety factor) for bolted connection can you please clear this doubts why difference in formula
Tdn is calculated per pitch length ,(not the whole length you took) 2.Vdsb and Vdpb will be multiplied by 3only instead of 6 as we consider one side of the joint.
you must calculate for 6 only not 3 bolts . each plate is involved in all 6 bolts ,If you were to find no of bolts required on the basis of Bolt value and total load . you would get 6 only.

Nice sir
Which software have you used for teaching ?
you have explained in the best possible way one can understand bro..keep doing and do a video on design of bolted connections pls

It is better to mention formula refered from Code Book with table Number
Why do were calculate the force based on pitch in some case and in others we calculate as a whole?
amazing lecture on this topic .thanks a lot sir for such lectures
You are welcome , Anup. Hope you have checked our website where we offer a lot more : learn.apseduverse.com
Respected sir i would like to ask one doubt (shear capacity of bolt of one bolt x 6) in butt joint what is the reason (17:40)

What is shear plane at skunk?
Apsed is doing great job. I would like to have complete lecture for ese/gate . Any suggestion.
Akash Abhishek Hello Aakash, complete lectures are available from our website. Have a look at it : learn.apseduverse.com
@@APSEDUVERSE thanq
i think u missing 0.9 in strength of solid plate
There is no need for .9 , see clause-6.2 of IS-456 . Here strength is due to yielding of gross section
Whenever section failure is yielding I.e limit state of serviceability no need to multiply by 0.9
@Vishal Gahane dono ka value sam hota hai
@Vishal Gahane but edge distance is denoted by 'e' and end distance is denoted by e' ☺ a/c to is456

Will not we consider block shear failure of plate here?? Plz answer sir
Sir, i think you forget to post part-2 of this Lecture 10. i think solution of second example is incomplete.
Thanks for noticing..I forgot to add it in playlist. Now it is there. You can see the following link also:

in formula that is fu only.. check IS800;2007 - class 10.3.4
thank you bhai..

Pradeep kumar I too have the same doubt
In some books the formula of strength of solid plate is (0.9×Ag×fu/safety factor) for bolted connection can you please clear this doubts why difference in formula
Sir i think in strength of plate only one bolt should consider instead of 3 as critical one should be consider
Tdn is calculated per pitch length ,(not the whole length you took)
2.Vdsb and Vdpb will be multiplied by 3only instead of 6 as we consider one side of the joint.
you must calculate for 6 only not 3 bolts . each plate is involved in all 6 bolts ,If you were to find no of bolts required on the basis of Bolt value and total load . you would get 6 only.
@APSED please provide the lecture of strength of plate in block shear

During the calculation of strength of bolt why the lesser value is taken between the shear strength and bear strength.....
is it ec3?
why did you add As also ?? In the book, they only take An
please clear the writings on your presentation, i can't read them clearly, thanks in advance

Explanation is nice, but hand writing is not easy to read. Please improve hand writing.
Digital pen makes it a bit like that. Nevertheless we are trying to improve.
