Bridge construction - Incremental Launching - 3D Animation

[@darkspeed62]

Does anyone know why at 5:55 the bridge span sits on tiny little stilts rather than sitting flush on the bridge support? Like, why such a small area of contact? If you're going to do that, why not just have smaller pillars holding the span in place?

[@jibeneyto91]

Well that's the function of the blue steel platform in the front right? Once this platform reachs every column, the concrete structure being launched behind it is forced to go in a straight line. Also they won't launch the bridge if there are strong winds or gusts

[@pakdestalin9685]

Its 2 am and my homework hasn't been done yet. Is this worth it? Yes ofc

[@louisvanheerden2332]

Precision! I always wanted to know how were the columns stabilised in the water?

[@TheDarkFalcon]

Is there anything actually keeping the bridge going straight except the platform is straight and its being pushed in a straightline? I would expect some sort of rail system or similar device to maintain its orientation. As it looks to be going over a viaduct there could be strong winds that could push it slighly off center, even if slightly off balence it could start torquing the construction end quite badly.

[@nicktasteless360]

exactly my thoughts too

[@donnabeddows]

Brilliant, my class of 6-7 year olds have been learning about Bridges and have had a lot of questions that I've been unable to answer, so this will answer some of them

[@alaanaimat6592]

which programm did you use for animation and modeling ?

[@attractive_status_5M]

Without engineering nothing is possible ❤️

[@user-ky6vw5up9m]

Incremental launching has been around for many decades all over the world. What is new is the scale of the bridges being built and computerised control of the jacking.

[@jclark2752]

The music loop got old Long before the video ended... But, I was left contemplating just how powerful those seemingly tiny hydraulic arms must be to move All that Bridge along by themselves! Hard to imagine it going so smoothly! Still, nice work!

[@eng.pedrohenriquesantos9427]

it's really a amazing software, but not always be the way to building it ! I do would like know name this software please ?

[@williamwhitman9073]

The major issue would be the increasingly larger horizontal jacking forces to move the added sections. Using a launching joist from the just finished previous section is a well-know method. This method is not, and would only work in animation.

[@tanmay_joshi_9]

superb explanatory video..... I got it very clearly, but I want to ask, how they push that constructed part of the bridge if there is a turned bridge or curved path of bridge?

[@wvolf]

If curved, only with constant radius, for obvious reasons

[@iancrone2906]

I appreciate the educational values your video has brought to me, the 'incremental launching method', as you call it, is quite interesting... Good luck with whatever you're up to these days.

[@CanalPlusCenter]

where the expansion joints?

[@funnysht5093]

kfir there invisible

[@Л.С.Мото]

kfir in between the "sections"

[@SsiolisP]

+kfir There are two expansion joints, one at each end of the completed bridge. They are not illustrated in this video but I speak with personal experience for I have worked on a bridge by incremental launching method. I've added Google map screenshots of the expansion joints on the actual bridge I worked on. prntscr.com/jx4plk prntscr.com/jx4qxz prntscr.com/jx4t9q prntscr.com/jx4u9j

[@elavson96]

Not much of a concern to be elaborated here,those are accessories that can be installed in site without affecting the entire sequence.It is more on the chronology of major activities as the work is on progress that is emphasized to give a glimpse of the basic concept of a methodology out of the conventional.Guardrails,utility ducts and transmission lines,all attachments that can be done out of the new level is omitted so as not to complicate the message it wishes to convey.

[@mailvraju]

has this method used. how continuity ensured as one need to weight till the concrete gains adequate strength at least 72 hrs for each casting. it is unclear how individual castings of concrete elements can continually moving with out any connections and supports while moving.

[@shaikhaneef2240]

Please provide names to the parts which ur providing to prepare bridge for better understanding

[@sealandbuilder1637]

This is fantastic method of Bridge Construction Industry. I been done this in 6 years in VSL International...

[@neurofiedyamato8763]

Can someone explain to me how they overcome the friction of sliding a heavy concrete bridge section?

[@vsr6t]

Teflon

[@kingofkicks0124]

Very good video of how a beam bridge is constructed very detailed and clear I want to be a civil engineer when I grow up

[@dushniystroi7295]

А не проще ли направляющие подшипники на опору поставить для продвижения полотна? Wouldn't it be easier if the bearing guides on the support to supply for the promotion of the canvas?

[@AerisReyha]

Nice video... It's very educational... Nowadays, many of flyover road and bridge construction use precasted concrete... It's faster than do it from scratch like this video...

[@jammerthegreat]

So many comments saying how this is a bad idea and won't work?? This is a well used and successful method in industry, takes a quick google if you don't believe me.

[@johnnyllooddte3415]

call me when you can launch a bridge without pillars in the water ,,,,, then i ll be impressed 1

[@jammerthegreat]

johnny llooddte call me when you find launching bridge that can cantilever over such a span? it's a cheap method compared to cable stayed, tied arch etc. that is if the river can support piers (no large ship traffic, etc). It's very effective :)

[@npk2012]

Excellent work. I hope some how it could be linked with the mathematical model info as it has allmost all information needed for final design: nose, box girder, central prestress, temporary & permanent bearings, jacks, piers (forgot temporary piers), abutments, casting yard ...

[@ffrreeddyy123456]

Woah! I never knew how computers worked before this! Thank you.

[@reangeldos]

BUEN VIDEO...ALGUIEN SABE EN QUE PROGRAMA FUE REALIZADO???'

[@bradenanderson6989]

So cool how the falsework slides out and is ready to be reused

[@hebz45]

Amazing work, and very educational, wish i came across this when i gave my bridge construction techniques presentation!

[@jorelmendoza8842]

I feel like this is what I would watch when I was a kid searching for random stuff like these on YT

[@monacityhomes5286]

nice animated video..........through this video i got whole concept of bridge construction .

[@cicciobrigante]

how long does it takes to make the animation? it's possible to do something similar for a rotational cable stayed bridge in few days?

[@alzenbalto7668]

What machine can push that heavy tonnes of concrete loads?

[@VladArtRo]

@wvolf which of them 2 did you use to let us see every stage of the building?

[@tinytonymaloney7832]

It's a brilliant bridge construction concept although I don't think I have ever seen it in reality, I would like to have seen the pier construction also. More interesting I thought was the graphics. Wish I could do that. BTW, what was the music track, sounds like Moby but I'm only taking a guess. 👍👍

[@danielferreiradesouza796]

good job! whats is the name of the software that you used to make this animation? thx

[@chaitaniya911]

what software have you used to make the video?

[@Rfc1394]

I am also curious as to what program was used to create this animation

[@suennyoliveira2060]

Hello, can anyone tell me what program was used to make the video of this model showing step by step? Thanks in advance if anyone can provide me with this information.

[@nawazyube]

great. have any bridges been constructed in this procedure? I am new to bridges, just taking the course. was curious to know if it is actually being done now or it is a new procedure?

[@9888565407]

hi are you still alive ?

[@gabrielfb1]

Incredible! With software did you used to produce this animated construction?

[@kiminig]

I don't think It is some new methods but i wonder what happen when there are curves in the bridge alignment?

[@kmed1994]

the best bridge building video i'v ever seen ♥ thanks a lot

[@evyze1]

Great job!

[@rc08x85]

Wow Great engineering machine and work😊 I didn't know that

[@didierngufu7971]

thank you for this tutorial. which software did you use to make this bridge construction process?

[@jankipatel-mi6mc]

hey guys

[@aibanez9181]

Is one of the best method for length over 600 meters, i worked on one of 1.4 km launching from both side.

[@juancarlossantoyo8000]

Y la fase de aplicación del presfuerzo?, ya que supongo que para "jugar" con los momentos flexionantes tuvo que utilizarse pre y potenzado

[@sitsiritsitmusika1468]

please enlighten me.. the first post that is submerge in water. did the continuos movement of concrete above it did not affect the strength integrity of the foundation ?

[@bigredc222]

Looks very cool, has this technique ever been used to build a real bridge?

[@wvolf]

Yes

[@scottgrafton68]

But what about the columns? How did they get there?

[@williamwhitman9073]

That's a separate issue, that is easily solved using piles or caissons.

[@eliosalomon6233]

God

[@Architect_from_future]

Классная понятливая анимация!

[@theliger1980]

Nice video Thank you very much. Specially sound effect which you have added. Again ... Thank you Is there animation for curved bridge?

[@wvolf]

It is possible in curved bridges yes. But with constant radius, for obvious reasons

[@victorutomi2125]

please could you explain the procedure for construction of coffer dam again.thanks

[@need4gears]

Uau muito bom! Quanto você cobrou por essa animação? Se não quiser dizer por aqui teria como me responder por mensagem inbox? Obrigado.

[@xXFroggyGamerXx]

O_O oh my god this guy is a PRO at doing animations!

[@johneastmond9092]

Great animation! Was there any lateral load calculation done on the towers/piers? That load could be prohibitive.

[@aadiadam]

Most probably, on basis of the safe design specification is how these members were casted.

[@dbigottt]

Very well video, what software did you use to made it? Qué programa se usa para hacer la animación?

[@danielroman7277]

Que programa de diseño 3d utilizan???

[@kabitalohala709]

what software they use to make such animations

[@luiscastillo9133]

how do you build those pillers in the river though

[@siphiwe6486]

Thanks for the video and clear construction sequence

[@georgescidmore5968]

Damn that was cool!

[@saepulpermanahidayat6329]

permission to share on my KZbin account because this will be useful, especially when the Jakarta-Bandung high-speed rail project is currently under construction

[@RuffaOzaeta]

Awesome!, what software did you use here?

[@unknownperson12396]

i watched this when i was younger and I'm able to see it again

[@KoalaMCVideos]

Interesting, never knew a bridge was made like that.

[@mastergaurauv]

every piece you add to bridge will require more power to push it on the ramp not very efficient

[@Aces77777]

Amazing video thank you who ever made it

[@apurin4939]

Fantastic......, Helpful for knowing about bridges

[@Kolastical]

Overall, this is one of the coolest animation jobs. However, I have the following concerns. Base cast expected at 2:12, b4 wall shutters come on, having the base to rest on. This is in addition 2 the bracing needed by the same wall shutters, which only came probably too late at 2:20. This design could be adopted to have a monolithic wall-base job, but the difficulty may come in at maintaining d desired base thickness, as d pressure exerted by d higher wall casts tends to raise the base level.

[@dakhabhai342]

Awesome 👌👌👍👍

[@gokulsivakumar4930]

incrementing should be done from both sides right... waiting with fingers crossed for the alignment to be accurate

[@Buckshot844]

Can this construction method be used for steel bridge construction? What about for bridges that are sloped and/or radius

[@Thefackerrooftop]

Good video! I like the music track a lot ^^

[@jpdmk]

Just amazing. Great engineering example.

[@pxanthos]

Excellent work!

[@MrB4lLiStIc]

Very nice!

[@brettclark4508]

Very cool it's meet to see every step.

[@187781jason]

Great!! Consistant quality, great job :)

[@TheCordoeiro]

I love so much this video! Thanks!

[@seyiajilore4043]

This is helpful. Is it possible to deploy this system for curved profile or alignment?

[@nicktasteless360]

i don't think so, but prefabricated segments manufactured in accordance to design specifications could be shipped and lifted up to the columns. Which i think is more efficient as you can assemble multiple segments at once rather than. Casting on site.

[@redshadow38]

amazing stuff! I have to prepare a presentation of the incremental launching and this video has helped me to understand it better! Thanks :)

[@Rainiexli]

This is amazing!

[@aragonkacena9185]

what program does this animation ?

awesome, great job. congrats and thank you.

[@ugochukwuogili7050]

Very nice video, i like it

[@cristianzarate3053]

Esto no causa gran tensión en medio?

[@protoborg]

the metal framework at the leading end seems like it would not be strong enough to support its own weight like that. It's a nice idea but seems a bit impractical. I could be wrong, though.

[@thisusernamehasntbeentaken5297]

+protoborg search up millau viaduct. Tallest bridge in the world was made by using this technique (source: another youtube video, with architects and engineers explaining it). it is much stronger than you think.

[@protoborg]

StrazzaDazza I'll take your word for it.

[@thisusernamehasntbeentaken5297]

protoborg I study engineering and we studied this technique for about 2 months. It does the job.

[@SsiolisP]

+protoborg I personally have worked on a bridge using this technique. Didn't understand it till I saw it in practice. The technique is called "Εκ Προωθήσεως" in Greek which means "to push forward". Just like this video illustrates, each new increment is pushed forward. On the bridge I worked on, each increment was 22 meters long, 18 meters wide and 4,5 meters tall. I don't recall the total cubic meter volume of concrete used for each increment. Interestingly, the 400m bridge was also going uphill at 4 degrees and it also curved to the left, meaning that this technique is not confined to straight, flat bridges. What amazed me the most was the hydraulic mechanism which literally pushes the entire weight of all the increments... pushing at 450bar the mechanism is smaller than what one would expect. It usually took us an entire day (07:00am to 23:00pm) to push forward each new increment.

[@Ahmad-Str]

+protoborg especially since it was supported only on one end, meaning that much moment was generated at its end

[@myrisiu]

excellent in clarity and beautiful rendering. very interesting watch.

[@HanyauntukAllah1]

excellent. I allow me to use this in my class for my students.

[@nachobusiness5295]

All looks good, but one thing... Where do we get the dark magic in order to make all of this stuff appear out of nowhere?

[@spartankongcountry6799]

That's a civil engineering secret 😂

[@jdmjoseduarte]

What’s with the ghetto “music”??

[@kingk5077]

Wow...Lovely back ground music

[@anandjakasania]

expansion joints in the concrete. ? ....

This has been simplified come on man

[@guntorojati]

total awesomeness, thanks a bunch

[@MySpace662]

Natural expansion joints will form through time.

[@619WWEFAN]

Can someone Plz explain why there is that gap under the bridge? Why don't they just fill it?

[@Christian-dx2by]

619WWEFAN I believe its because of wait it would way too much to work if hey filled it in

[@619WWEFAN]

Christian martell it cannot take that long, can it? Could there be some safety reason?

[@InspektorDogge]
