Very useful! worth noting the 0.6 shear factor can be different, in Eurocodes it can be 0.5 also!

An excellent video tutorial !!
Thank you so much !!

[rajaazhakesh]

Great work sir . Great respect to you sir

[maliknasrullahkhankhan]

excellent tutorials sir calculations made easy

Thanks for the video. How do you account for bending stress on the bolt if the connecting plates have more spacing between them than this simple case?

[jesuseduardoaldanamarquez]

Great video and so helpful, I wonder if the partial safety factor can vary its value in the formula?

[joecortizo]

Thanks for it!
Any particular standard we can refer to?

[henriqueernande]

Thanks for the explanation, In the case of the middle plate will thicker than the plates of the extremity?

It's well explained and all the information is correct but omits some important information about group capacity. As it's poor practice to have single bolt connections in multi bolt connections for simply supported beams, beam flexure causes rotation of bolt holes which increases the load on the bolts. Although I don't believe this is directly covered by EN 1993-1 other literature does cover this such as The Steel Designer Manual 25.4.2 and SN017 where bolt shear capacity (or additional force applied) is reduced based based on bolt group geometry. It my be helpful to add this or create a separate video if you have not already. I ran some FE models and the effect is real, think it was something like 27% of vertical shear for a typical beam which tied in with SN017

Do you obtain total capacity by multiplying the shown result by number of bolts? Doesn't mater of their configuration? (bolts beside each other or one above the other)

Hi mate. Thanks for this very informative video. If I may ask, what code that refers your bolt min. distance and edge distance? Thanks

By the way. Im one of your subrcirber now and Im keep on following your channel. Thanks mate

[MrSadfhg]

would like to know the reference of ur calculating method.

[fatimaasif]

When you calculated the bearing capacity for the example in single shear, where did you get 410 for the UTS for S275? Is that the UTS for S275 for all plates of a thickness 10mm? If so are you able to link the website where I can find those figures from? Thanks

[sairaj]

Great video! Could you tell me the source of the Bearing capacity equations? A citation would be great!

[ambroseliu]

Where is the tensile area actually referring to? If I have a longer thread engagement, would it change the tensile area?

[bonjournito]

How about shear, axial and bending combined?

[elisemusters]

Hi! i was wondering if we have connection with multiple bolts of for example a resistance of 70 kN each (280 kN resistance in total). The force applied is 200 kN, is this then sufficient? Im asking this in relation to failure of one of the bolts for example. Should another safety factor be taken into account or should we for example design as if the full 200 kN is exerted to 1 bolt at an instant? I would love to hear from you what the best way is.

👏👏👏

Anyway of seeing what calcs you have planned ahead?

I work for a leading consultancy in the UK.. and what you are doing, is taking the IstructE papers.... And doing a video tutorial version.

I cannot stress how much these have been missing.

Every engineering firm I've been at, there's always been (along with the code of conduct) a nessessity to share knowledge. However, to get that from the main engineering bodies, I have to have 3 memberships which is over £500 pa. On top of that, you need to pay a few hundred quid to do the day courses.

It solely restricts the individuals to either pay and they may not be able to afford it.

You remind me ALOT of the KHAN Academy. Nobody should be restricted access to this type of content. You really are a credit to the engineer field.

How many are there of you?

[printlife]

is the calculation based on any standard or reference? like ISO, or DIN, JIS?

[farahalzahari]

May I know what is the value of 0.6 stands for?
