Hello dude. Since first time I knew you, I realized that you have a huge talent to share your knowledge. I hope I can take a course of yours this year. God blesses you.
Hi Lukasz, nice video. I use also RFEM and for stability calculations as rule of thumb I use 8 elements per beam to capture most important buckling modes/scenarios. I think it is even recommended by RFEM developers in application manual.
Hey! As a rule of thumb, I want to have at least 5-6 elements per "wave" of buckling. But if I can "get away" with 8-10 then sure. It all depends on the model size - in beam models I don't like to wait long for outcomes :P Good point - thanks for bringing it up!
awsome video lukaz,,,i am meber of your FEA online course , being from civil engineering background i enjoy this video...please include this example in the online course too.
Hey! I'm really happy that you like the video Alex. I have plans for adding more stuff for the online course for sure :) I will put this on the list ;)
@@Enterfea hey lukaz ...please too add this video in the online course list as there are no examples related to this topic . Also i would like to know how can we extend this concept to SWAY frames ( or unbraced frames) for multistorey buildings, as the beam stiffnees would participate in it. how this can be acheived?
Hey Alex! Thanks for the suggestion. Check the premium part of the course I discussed stability there on 2 different occasion - one with a very complex model of a multistory building (with some crazy bracings :) ) As for your suggestion, in general, I try to keep my course (enterfea.com/learning-fea/) on the topic of Finite Element Analysis. I don't want to go too deep into the stability, as this is somewhat specific, and many course users won't be interested in those subjects. Still, there is plenty of stuff about stability there I think. I admit that I have a PhD in structural stability... I would love to create a course about it (many more courses in fact!), but knowing how much time it takes... this will be a long process for sure!

Thank you Tony! I'm really glad that you like my work :)
