You don't see many structrual engineers taking time out of there busy life to teach others especially for free! This channel has helped me grow significantly! You’re a constant reminder that people can be good keep it up secalcs! :)
Another great video. If only you'd been around when i studied my degree 30 years ago. You explain everything so clearly and its immediately understandable. Excellent. I'm hooked!
It would be great to see some more advanced calculations ; for example an IStructE exam question example and maybe some advise on structure. Appreciate the videos, it’s always helpful to have simple calc tutorials even for more experienced engineers!
Great video, but I have a question. Are those 2.5% mentioned somewhere in the some code, because how should I argument my point of view that it is enough, maybe 3% or 5 % need to be taken? You mentioned that steel beems have a tendency, I assume that it is due to the shape which they are produced and placed in the structure. If it would be a solid block but still in steel, then it should not have such problems. Additionally, I assume timber I-joists also can have such problem due to the form, but it can be neglected as they are covered with some sheet and fastened to it which creates quite a rigid system.
According to BS 5950, for one or two restraints, the members must be able to withstand a total force of 2.5 percent of the maximum compressive force in the beam, divided amongst the restraints in proportion to their spacing; for three or more restraints, each restraint should be able to withstand 1% of the maximum compressive force or the 2.5% force distributed in proportion to the restraint spacing. Eurocode 3 (BS EN 1993-1-1), Clause 6.3.2 explains that in order for a steel beam element to be classed as ‘restrained’, its compression flange must have sufficient restraint to prevent lateral torsional buckling. Beams with certain types of cross sections such as closed hollow sections with a height/depth ratio of less than or equal to 2, are not susceptible to lateral torsional buckling.

Thank you very much...I can not thank you enough. I still await your pile cap design.
Coming soon!
Hi, thank you so much for your videos. Would you happen to have any references for the 2.5% requirement?
Yet another great video... Many thanks

@@StructuralEngineerCalcs Thanks a lot for such a detailed explanation
Very nice video ❤
