The Impressive Engineering of the Roman Arch

Patreon: patreon.com/ConcerningReality
FB: ConcerningReality/
The arch bridge and arched structures allowed the Romans to construct buildings with a far greater ratio of wall openings to height than had ever been possible before. The evidence of such architecture is found in not only the Roman Coliseum but also the labyrinth of arched catacombs that lie beneath historic Rome. Focusing in on the arch bridge, it was a technology never seen before, one that allowed boats to pass under walkways and roads and one that enabled the Roman’s famous series of raised aqueducts.
Why was the arched bridge so crucial to the roman empire, and what structural properties of the arch have that enabled roman architecture to survive relatively in-tact even to modern times?

Thank you for making this video using this in my grade 7 presentation on arch’s. My whole class is going to see this

Мне 73 и меня всю жизнь восхищают и завораживают каменные арки ! А сравнительно недавно я был шокирован информацией о том, что некоторые арочные мосты , маяки , стены сложены из камня без использования раствора . И стоят до сих пор ! А кто такие этруски ? В русском языке, без перевода , этруски - это русские ! Из Сибири с уважением,Владимир Мой город-Нижневартовск-Nizhnevartovsk!

You should mention La sagrada familia. Where the architecht used a model of the church, flipped it upside down and used strings to find out how the arches would be built for the perfect compression.

[@chain3519]

Most Roman arches you see are actually solid cast concrete with a brick facade.

for the same reason , people say greeks invented the phalanx ... the history have been heavily rewritten in the 1800's ... now welcome to euro centrism .

[@wokevirushandsanitzer5300]

The Romans spread it everywhere. Almost every place they controlled at some point displays their architectural techniques. Even places like Britain. It’s the same with everything, we often don’t name things after the original creator of that thing. The light bulb isn’t called the “Edison’s light creator” it’s just called a light bulb.

I want to build a stone arch up the mountain. The blouders are free as they roll onto the roads from the mountain sides. I can use tree poles for the tripod crane along with a logging grapple and a chain block for lifting.

Stone Arch is one of those things that we should build things like inferstucter out of...not cheaper fast produced desolving materials. Cost more in the long run...liked like 4.5 trillion currently today to fix everything

[@TheNonplayer]

I totaly agree on that standpoint.... todays infrastructure, the backbone to all we do is been done cheap, weak and often quite sloppy... I just got to know that a bridge in the usa would last on average 43 years or so... that's insane (in my eyes). with a little more effort, some more money they would last centuries.....................................................

[@dangerdan2592]

@@TheNonplayer It is insane to me too. We should be building bridges that last hundreds of years at least. They would probably charge more but it would be worth it. But hey, then that same company can't come back in 43 years and build the next bridge with a short life span lol. I say this as someone who knows very little about building bridges or architecture in general.

[@TheNonplayer]

@@dangerdan2592 hmm.. isn't the real goal of us inventing machines and such to make our lives easyer and make us do less work? in stead we try to invent work, just to have a job and pay our bills.... this is essentially what's wrong with the modern world, we are still focussed on "making a living" instead of doing just what we need to do and advance a bit here and there; work less and have free time to spend with others around us and dedicate our time to educate ourselves more, do some spirituall things.. make some art or travel around the world all the time so that at the end of our lives we can look back on a full and well lived life. and making quallity stuff in stead of all those piles of throw-away junk helps a lot in that regard and in other area's aswell (like polution and mental health)

[@hereb4theend]

@@howmuchbeforechamp Well just look at Roman or Greek style architectures. The scale, precision and intricacies of their sculptures, cathedrals and towers can't be replicated at all. Not by modern tools and not by people that only had horses and buggies to get around. The people that built these magnificent cities are long gone and we merely inherited it. It's no surprise then that all we can do is REsearch, disCOVER and be "Founders".

Why don't we use ash in concrete today?

[@jeremydjabouti8960]

We use carbon fibers in a lot of it

[@TinyBearTim]

Because we are idiots that think steel rods are good ideas

[@iCanHazTwentyLetters]

We do use various forms of ash, such as fly ash from coal power plants. And the statements about roman concrete being superior to todays concrete is misleading. The video author has misunderstood / overestimated the durability of roman cement. Modern cement is less durable mostly because of the steel rebar that rusts and/or fatigues and/or cracking occurs because of different thermal expansion between the constituents of this composite material.

[@daviedood2503]

Volcanic ash is expensive as hell to get and Transport to make Roman cement.

It's not the roman who invented arch, they invented concrete as a material to build arch which enable them to build arches bigger in scale and complexity.

The Romans invented the Self-Supporting Arch, period. They also invented hydraulic cement and a type of cement for dry structural applications. Everyone else was using localized recipes for mortars, which lack the compressive strength of cement. The Greeks did not have the self-supporting arch, and relied on rectangular wall openings with a plinth across the top of two columns or posts. Same with the Egyptians, who didn't even have free standing statues. The Greeks were the first to do that, bu they never got any further on the arch. That's why no ancient Greek building was more than two or three stories tall, whereas the Romans built five and seven story buildings they called condominiums. The only exception to Greek building height was the temples, which were supported by columns, having plinths across the tops. It was Roman building principles that were the basis for the great cathedrals and all bridges, as well as the beautiful architecture of the Islamic Golden Age. The self-supporting arch was the basis for all architecture up until pre-stressed concrete and welded and riverted iron works was invented, which made modern sky scapers possible. The Romans were the world's greatest architectural engineers until the 1950's, and put the Egyptians to shame. The pyramids are simple by comparison to Roman engineering - just very big.
