ESDEP - European Steel Design Education Programme These are not my videos, I found the CD's somewhere and uploaded them for everyones use. No copyright fringe intended.
The end credits show a date of 1986 but it could easily have been from 15 years earlier as produced by the Open University. All that was missing was a chap in cavalry twill trousers and a Tattersall shirt with a narrow knitted scarf, smoking a pipe, having previously hung up his tweed jacket with leather patches on the elbows.
Thank you for the video Sir! I have an exam in two weeks and i love to see how this happens in real life to get a good understanding of it. Greetings from Germany.
These days the section if the 'stocky beam' as its called in this is square, then it is called a universal column or UC and if it's I in shape (so the old I beam nomenclature) then a universal beam or UB. In the steel business (rather than the engineering business) they are always UB or UC so everyone knows if it's a column or a beam. I transport and deliver these in lengths of up to 22m but most commonly in the range of 12-15m. One I delivered the other day was 14t for a 12m beam but it was a welded one off and would have to be made to order. By far the most common ones are rolled. For these type of beams remember this rule of thumb, If the height is greater than the width = UB (universal beam) If its a square, so the height and the width are the same = UC (universal column)
The section shape is not the only difference. The steel's material properties also have an effect, where steel may be rolled for compressional or bending purposes. Beams can be H section as well as columns, and yet function differently. You are unlikely to see a steel I beam of lengths beyond those because of material limitations. Members longer than that are usually designed as truss elements, which are much more efficient in comparison to their self weight
Very educational! Qualitative rather than quantitative. Bracing of beams - your ordinary carpenter has been doing that with timber first floors for years - i.e. herring bone strutting and bridging between floor joists - and of course the floorboards nailed to those joists restrain the top edge.
Nice old timey engineering video. The concepts are still valid. 5 minutes of dead air time (snow) at the end. We used to call the image on a TV "snow" when no signal was broadcast. I think maybe this was a video tape of a movie shot on "film".... ask your grandpa what film movies were... called the "flicks" in the really old days.
2023 - much appreciated. Flash backs to the lab - without the pressure to takes notes, understand my notes and observe all at the same time for a cluttered mind 😂
When loads are applied to top flange (compression flange) additional torsion distortions may occur . Studs are welded and cast into concrete deck . We use AISC formulas in United States ASD or LFRD . Dynamic loading and temperature expansion forces also must be considered. Nice ,Thank you.
I’m not in the engineering community, but I’ve not seen I beams “bolted” together in many years, everything’s welded together now. Having said that, engineers still have to “characterize” beams and put them through actual laboratory tests to validate the performance is as reported.
Fuck me standing there no orange jacket no hard hat glasses of ear defenders damm he should have been in a million bits 🤣 Or could it be back then common sense applied
A good video to give some visual insight in the behaviour of beams. You can calculate something but actually seeing something moving/bending under a load is very informative. However the film quality is really "seventies/eighties/VHS?" bad.
Look, a real life reason for algebra. Thought I’d never see that. I usually just overkill the beam when I use them in simple construction applications.
Does it melt when jet fuel burns on it? Can it collapse at free fall speed with zero resistance to the beams that had no heat ? Would it cause a near by building to also collapse at free fall speed ?
Apparent similar instability situation where all adverse conditions are observed plus heavy corrosion in progress on the longest structural cantilever span ever built. That is the 100 years plus, Québec bridge. Search and see Flickr/ Rouille et déformations sur le pont de Québec.
burning in open space or free not really, burnig in conditions like in the jet engine, high pressure fast moving air, pulverised fuel etc etc ....burn even thru titan alloys. some special ceramics will stand a chance. the magic of the jet engine is not let the flame touch anything in the engine.
Hi dear Thank u for this useful video I just would like if u give me the dimensions of the beams in 11:44 Please help me Coz I need this dimensions in my education project Plz Reply me soon 🥺
