- In this video, we will be discussing the critical role that holding down bolts play in construction & how to properly calculate their tension capacity & pull out resistance. Whether you're building a new structure or renovating an existing one, it's essential to ensure that these bolts are strong enough to withstand the expected forces & keep your building secure.
Our tutorial will guide you through the steps to calculate the tension capacity of the bolts, taking into account factors such as size, grade, & expected tension force. We will also show you how to determine the pull-out resistance of the concrete, considering factors such as overall bolt length, clear projection above the nut, & thickness of various materials.
It's important to compare the tension force to both the tension capacity & pull out resistance to ensure the bolts are sufficient for the job. If these values are not sufficient, we will explain what steps you can take to adjust them.
By the end of this video, you will have a thorough understanding of the importance of holding down bolts & how to properly calculate their capacity and resistance. This knowledge will give you the confidence to ensure that your structures are secure and stable. Thank you for watching!

Amazing tutorial as usual, hope to watch check of tear out too , thanks in advance
Thanks a lot for the videos, they are simple and straight forward.
Are you by any chance going to do structural analysis involving Matrices and Finite Element End, and indepth of Reinforced concrete design?
Thank you for your positive feedback on the videos. We are glad that you found them to be simple & straightforward.
As for your question about future videos on structural analysis involving matrices & finite element method, & in-depth reinforced concrete design, we are always looking to expand our content & provide valuable information to our viewers. We will consider creating videos on those topics in the future, & will keep our viewers informed about new content. Thank you for your suggestion.
@@StructuralEngineerCalcs Alright thanks a lot, we will be waiting.
@@StructuralEngineerCalcs Also if time allows, would you also add some few questions at the end of the lecture for us to answer then provide us with the worked solutions of questions. I just want to expand the knowledge in the topics so that I am able to be your content and the one I am studying.
Where did you find the formula for pull out resistance? How about checking for concrete cone pullout?
Thank you for your comment! The formula for pull-out resistance can be found in various structural engineering references, such as the British Constructional Steelwork Association's HD Bolts document. As for checking for concrete cone pull out, that is not something we covered in this tutorial. However, you can use similar methods to calculate the pull out resistance of concrete cones as we used for holding down bolts. The main difference would be in the effective surface area & the shape of the cone. I hope that helps! If you have any other questions, don't hesitate to ask.
@@StructuralEngineerCalcs interresting. I’ve been looking for a formula for embedment depth in the eurocodes for a long time. Will have to check it out.
If the bolt is m20 how come the nut is 16 mm dia 😢
