*_Great video... comprehensive yet understandable to average non-engineer..._* One thing all these different bridge types have in common is they must resist gravity. The larger and heavier the bridge, the sturdier it has to be. And, all of them look easy to build on paper. Site prep can be extensive. Some civil projects require constructing roads to the building site. Many areas in Japan and Chine have rugged terrain. Cut and fill, retaining structures, drainage, etc all have to be done before the bridge can even be started. *_We have 'Floating Bridges' across Lake Washington in Seattle. Who says thousands of tons of Concrete can't float?_*
I think the arc adds to the structural integrity of a suspension bridge by giving it better stability and weight distribution in respect to its suspension ropes and their location. Non suspension bridges don't benefit from being built with said arc because it's integrity comes almost entirely from beneath it. If im not mistaken on these bridges you'll find that although they have flat/level roads they usually feature support structures that use an arc design on the supporting framework of the bridge. I'm sure there's probably various reasons though. They sure are fascinating structures aren't they.
There are some really really smart people in this world
im more fascinated with the people who are brave enough to build all of this shit lol
which city is the first in the video
Nice one, I wish I can also do this and also know how to build bridge and house
Start by drawing and making models, hobbies grow
Bridge Engineers are very intelligent
Wow 😦

Very broad overview.
Nice one
Why ar non suspension bridges flat while suspension bridges are arced in the center ?

Can one learn to be a qualified engineer online
Sorry but this video is largely generic stuff not about deep water techniques at all. Very disappointing.
