Another amazing video SEcalcs!! Thank you for posting. Great content! :)

@steelramesh 2 года назад

Your videos are like brain tonic for structural engineers✌️

@johnklekotka1028 Месяц назад

Nice explanation. In the old AISC allowance stress design, you could just look up the tension or shear allowables for any size bolt. But this is a good refresher as to how those values are derived. 👍

so simple!!!, thanks man!

@AkshayVVP Год назад

Thanks for simplifying these calculations. Can you please advise the code or standard where you referred this formula from?

@mountainbiker9330 Год назад

Thanks for this.

awesome bro 👏

@vtbhanukiran1231 Год назад

Great explanation. You are a very good teacher. Thank you very much.

@zaldyquedilig9866 Год назад

Great and informative.. can you make a video on right spacing/distancing of bolt use as anchor point to achieve its maximum strength..thank you

@omavowaneferire4822 Год назад

good stuff.

@fconsult_id6019 2 года назад

Great! Could you share the reference code/standard of above formula?

@sndesigncentre4011 Год назад

Thank you so much sir, but i am request you to prepare tutorial on minimum embedded length of anchor bolt

@cool7966 2 года назад

Easy to understand for bolt diamter however i have question related how you determine depth of rock anchor with example?

@robertbheatcoker8638 2 года назад

Great ¡ really easy to understand and straight to the point. What about when there is a combination of tensile and shear stress on bolt due a moment on the base?, Thanks

@swiftworkshaha 2 года назад

Did you ever get the response on this, great question.

@orfeaspapaioannou2755 Год назад

In that case (general case), you have to make use of the Bolt interaction curve - Combined shear and tension Fv,Ed / Fv,Rd + (Ft,Ed / Ft,Rd) / 1.4 ≤ 1.0

@rndtechinfokannada 2 года назад

Great I really easy to understand and straight to the point it feels me very very easy. What is 0.9 value from where is coming?

@orfeaspapaioannou2755 Год назад

k2 is a coefficient that takes values k2 = 0.63 for countersunk bolts or k2 = 0.9 otherwise. (EN1993-1-8 Table 3.4)

@MrMuhammadhafizuddin Год назад

Great Calculation, could you please share the reference of the formula?

Could ypo please make a video to calculate the bolt diameter required to resist internal pressure

@nazlhilalkutlay4078 Год назад

What are your references for the formula used? Which books?

@emadalhafez6172 3 года назад

Thank u.. Very useful ..but how caleculate distant bolt in concrete base

@StructuralEngineerCalcs 3 года назад

Thanks for your comment. We will do a video to take your through the steps!

@immanuelgaseb9119 Год назад

Which books do you use ?

@bonjournito Год назад

Highly over simplified formula! What is the bolt pretension?

@er.lalitbhatt7343 3 года назад

So, while calculating the bolt sizes and it's adequacy don't we need to check the bolt against Horizontal Shear force at base level ? It may be critical considering shear force too. What's your view regarding it. Please elaborate. Thank you

@StructuralEngineerCalcs 3 года назад

Thank you for your comment.This example is merely to explain how to work out the bolt size which is mainly subjected to uplift. The shear force has not been considered in this example however the worst case dictates the design. If there is a shear force you would have to include this in your design!

@Calligraphybooster Месяц назад

Times another 0.8 roughly?

@Pgan803 5 месяцев назад

why you did not include anchorage bond length of the bolt?

@Sitche 3 года назад

Thanks for the video, may you do a simplified analysis of multispan pitched portal frames

@StructuralEngineerCalcs 3 года назад

Thanks for your comment. Added to our list. Stay tuned!

@sathiskumar2191 10 месяцев назад

Where did find tension area of the bolt? Please tell me standard or something, thanks

@konstantinoszantis2977 2 года назад

Could you share a source for the Ft formula? From what book/journal did you get it from?

@LimuelGepitulan 10 месяцев назад

Can you please continue the table up to 32 mm dia bolt with respect to tension area....

@Simon-eg4xk Год назад

Good Video, but what does this mean for bending moments and concrete? Its very simple to calculate the diameter, but thats not enough.

@StructuralEngineerCalcs Год назад

Thank you for your comment! You are correct that calculating the diameter of the holding down bolts is not enough to ensure the stability & strength of a structure. In addition to the diameter of the bolts, it is also important to consider the bending moments & concrete in the design of a structure. We just uploaded a new video that might be of interest to you. It covers the importance of holding down bolts in construction & how to calculate their tension capacity & pull-out resistance. We hope you find it helpful and informative. Thanks for watching!
