The Impressive Engineering of the Roman Arch

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

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.

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 !

I have a thing for arches...these things are cool both visually and in their construction.Nowadays there's not enough of these things in society. Ancient technology, don't knock it!.

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

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

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.

Such perfection from a more advanced civilization that no longer exists.

A polite suggestion for your audio: consider a pop filter.
Or just use the pen method, put a pen to your lips while recording and it will help take the pop away from your P and T sounds, and lessen the TH as well, but I would suggest just getting a decent filter.

Cool channel btw

Why do we call it Roman arch, and it was already used in Babylon ?

[OverlordGaming]

Why don't we use ash in concrete today?

[greenpepper]

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.
