Two combined flat trusses maximum load experiment in a real conditions by VIRI TECHNOLOGIJA

It will increase it when you add a plat on both side

i will love to have it in africa

Nice load test up to failure. The maximum usable load would usually be determined by the maximum allowable deflection. If we select a maximum of L/360 (for a roof truss with ceiling or a floor truss) that would be 6000 mm / 360 = 16.6 mm.

To stay below that deflection a load of about 1500 kg or about 250 kg/m would be a reasonable limit. This is also less than half of the load at failure, which provides a safety factor of approximately 2.

I wonder what the calculated load limit of these trusses is?

Great video 👍
This is the type of information I am looking for.

Great, BRABVO, The cost of the building with 4 story without column inside flooring : span 20 m x 60 m long x 2 m height of each story , roofon type : crossover

good test, cool music ;)

what title this music?😁

(3225/6)/2=268

A lot of people know lbs rather than kg. Also, unbelievable crappy background music

How long is this Sir?

Still couldn't support your mother.

Is there any counter check on theoritical calculation on deflection..if it is match on actual deflection

Wow kudos to the team taking the effort to make this video

*It is a fake video, the inclined parts are reinforced by
inside, except in the inclined parts that are in the center.
Those cans don't hold that much weight.🤣🤣🤣🤣🤣🤣*

On concern that I have regards fire resistance. It needs some protection

You're lucky that didn't buckle outwards! Those paving slabs into shin would have been very painful

What gauge is the steel?

Very helpful test !!! Thank you so much !!!

MADE IN "USSR"ALWAYS BEEN THE BEST.

Well I'm building a 24 inch tall 35 ft long truss out of 2 1/2 x2 1/2 x 1/4 inch angle iron top and bottom. And using 2x2x1/4 angle iron for x bracing. I'm sure by watching your
video it will be strong enough. Thanks for your video.
May use the bottom for a trolley

the load on the far right and far left are not supported by the truss but the vertical support from the ground. So the test is a little skewed as to total load supported.

А 12 метров перекрыть сможет? Какая толщина фермы будет при этом? Без опор разумеется.

Я помню.

Muito frinds ok

540 / 2 since you had two trusses?

No load the weight just in the middle. Bet under half the weight it would fail

А в каких конструкциях вы предлагаете это применять?

Значит эти две фермы можно заменить швеллером 24П по ГОСТ 8240-89 из стали Ст3, и прогиб будет меньше. А если посередине поставить распорку, (поперёк пролета) то можно и 7,5 т. (1250 кг/м) накидать. Кстати, по прогибу эти фермы не прошли уже на 450 кг/м. Сколько стоит две таких фермы? - надеюсь дешевле 144 кг. швеллера.

Should have done a demensionally equal wooden truss comparison.

The weight on the ends means nothing. Defection happens in the middle .stack the blocks only in the middle , that will give you the deflection .

Seeing where and how it failed I have to wonder if a build up of metal in that area to create an egg like round corner in all the point areas may help increase the strength and by how much?

Good test

3225кг/2/6/3=90кг/м2 с учётом расстояния между балками

Говно от снега мокрого и мороз с чередованием это шовно не выдержит

Собственно наглядная демонстрация отвратительной стойкости ЛСТК к прогрессирующему обрушению. Держит нагрузку до тех пор, пока не нарушена геометрическая целостность профилей, при малейшем её изменении рушится мгновенно, как карточный домик и не обязательно давать огромную нагрузку. У конструкций из сортового проката в этом плане всё гораздо лучше.

Please, now all the experts can explain why it’s wrong. 😳

Live load would accelerate that.

this is not a good test weight applyed even if pulling an engine would be on center only

Детские забавы. Поставьте весь груз в центральную часть балки и узнаете сколько она выдержит нагрузки.

Okay now do that again and at 3,000 kg take all the weight off and see how much deflection comes back.

Я это ♥️ называется видио проверка в натуральном и живом исполнении

Although this is an impressive experiment, it shouldn't be a substitute for a real structural engineer's analysis.

СПАСИБО ЗА ТЭСТ.

Good video. Would it be better to use screws or rivets for attaching the 45 degree braces to the main beams?

This design of member can be adjusted . Like lay link in rebar insitu beam .

More close member both 1/4 span .
1/4 both top make dauble layer
Then 2/4 bottom layer make it double layer .

This is basic design for Maxima load of beam .

After we doing new design like this . It can carry load more then 10 ton . 😁😁😁✌️

Cool experiment

very good mild steel greetings from Indonesia👍👍👍

realistic demo. thank you.

shit! i thought this was a bar joist test!

Thanks , very good job
