Bolted Connection Design - Eccentric Loading | Design of Steel Structures

APSEd Website: learn.apsed.in/
Enrol today in our site learn.apsed.in/ and get access to our study package comprising of video lectures, study material, practice questions and test series with doubt support for Civil Engineering competitive exams of GATE, ESE etc starting from Rs.1599!
APSEd is an educational platform by IIT Bombay graduates. For queries, you can contact us by mail at [e-mail] or alternatively contact us at [phone]
In this video I have talked about the design of bolted connections for eccentric loading when the bolts and load is in the same plane as well as when the bolts and load are not in the same plane.
Hello everyone, hope you liked the video. This is an educational platform set up IIT Bombay Graduates with an aim to prepare you for competitive exams like GATE, ESE, etc., and to widen your knowledge in Civil Engineering.

Mast bhaii.... Accha haii

Thanks a lot sir, because of your lectures I cleared all my doubts.and keep on.

Thank you sir😊💕this helped a lot

[@harleyjune1233]

in case 2 - Out-of-Plane Eccentric Shear Load - why do we assume h/7? (AISC uses h/6 as 1st stab) if the vertical leg is (for example - h=12" . with 3 bolts equal space/distance h/7 - = 1.7 . this puts compression below last bolt -meaning all 3 bolts in tension....thank you in advance - maybe illustrate iterative procedure to locate NA with moment of inertia tension and compression bolts?

[@vitolongo4511]

isn't it just a different code where the. factor of safety is less? h/6>h/7? once you incorporate a factor of safety it inherently loses accuracy. The safety becomes more probabilistic. Does this make sense?

[@kumareshbiswas5798]

thks sir....sir steel ke bad som start kijiye it will more helpfull for me...

[@APSEDUVERSE]

I have asked my friends from structural engineering specialization to take SOM, Structure and RCC. They will start in sometime.

[@mukeshkryadav5053]

Thank u so much sir, this topic useful for me

[@pawanjoshi8035]

why are we taking resultant about the above extrem bolt? if you take combination of force about lower extreme bolt it will b greater as cosine for these forces is greater? why not take this bolt as critical

[@ajithm1256]

sir, In number of bolt calculation you are consider exernal moment only but direct shear due to p not consider ,why sir?

[@kumareshbiswas5798]

OK sir ...thkq so much..

[@تعليماللغهالانجليزية-ل4ش]

why the force proportional to the radial distance

[@shivamsharanlall672]

So after one year have you got the answer? As I am also searching for the same thing.

[@chandreshvaryadav1583]

Bez that is tortional shaer force , and from T/j =t/r,(t >tau ). Torsional foce came into action due to moment.

[@shivamsharanlall672]

@@chandreshvaryadav1583 I thought a lot about it. As per my thinking if you take 2 situations. First when there are 5 bolts in the connection at radius "r1" and then a second situation when 5 bolts are there at radius "r2". r1 < r2, then what do you think F1 > F2 or not? The bolts are equally spaced.

[@shivamsharanlall672]

Since P*e = Summation( F1*r1) = Summation (F2*r2) Also F1/F2= r2/r1 > 1 So F1 >F2

[@shivamsharanlall672]

When you combine the two bolting condition together such that 5 bolts at r1 and 5 bolts at r2 then then more twisting force is absorbed by bolts at r2 than at r1.

[@praveenkumartce5248]

Thanks a lot sir.. u have given such great crisp of this topic... Am real fan of your teaching sir

[@shailendrarathore8247]

Why tesion above the N.A and compression below the N.A?

[@najmanaurinvadakkethodi7242]

load is acting downwards,eccentrically to connection(here bolts) causes bending action to the gusset plate. so the portion above na hve tension and below na have compression

[@civilenggmcq7926]

resultant f^2 should be fi^2+f2^2-2f1f2cos@

[@APSEDUVERSE]

Plus will come..Check the solution here: apsedtraining.blogspot.in/

[@civilenggmcq7926]

www.quora.com/Two-forces-each-numerically-equal-to-10-dynes-are-acting-What-is-their-resultant HERE ANGLE @ is outside of side not between them

[@swarajjayswal1036]

Sir is right... actually its all about how you conceive it...the resultant will be the diagonal of parallelogram formed by the two forces.. so simply you can shift that "theta" outside by considering parallel side of F2 force....both will give same result! secondly if you see the cos@ will only be negative when @ is higher than 90 degree. Hope you got it!!

[@civilenggmcq7926]

thanks for reply but i forget everything now . i wanna see it at revision time

[@swarajjayswal1036]

Didn't you make short notes of your own? this may create a mess in the last month.

[@omto.m]

channel doesn't Grow because they never replies to any comments

[@akramshaikh467]

Writing achaase nikalo bhai

[@subrahmanyamb8581]

Thx a lot..git heloed for my bolt calculation...in second case how do we calculate the stress in the plate where bolts r connected..is it same tensile forces calculated by area if plate??
