Golden Gate Bridge | The CRAZY Engineering behind it

The design and construction of the Golden gate bridge led to revolution in Civil engineering. Let's understand all the magical engineering behind the Golden gate bridge.

Hello everyone, your support is crucial to us.

I appreciate that they went above and beyond to create a 3D version of the engineer, just so we can see him proudly cross his arms..

Very realistic animation. Especially the part where one worker ran the cable while 2 others just stared at the water. 😂

[JohnSmith-nwls]

Designing and rendering a 15 minute animation like this is also quite a feat of engineering, especially one with as much detail as this one. Thank you so much for all the hard work and time putting this together

I appreciate how the sharks just calmly watch the divers working to place the bombs, like "Leave em alone, they're doing complicated work here.."

[okdarius]

I'm not even that into civil engineering but this was REALLY fascinating to watch and learn about.

[samarthbarshi]

They made all this in a time when there was no CAD and other simulation softwares. It's truly remarkable.

Anyone else here after Baltimore's Key Bridge accident and collapse?👀 Great video, by the way. Very insightful!

Shout-out to the construction workers for risking their lives to make this project a reality

14:33 I attended the bridge's 50th anniversary in 1987. When the bridge operators approved the temporary closure to vehicles, they estimated 50, 000 would attend. The actual number was estimated at peak, close to 800, 000 had come, far more than could even fit on the bridge. You can find photos that show masses of people stretching back on to land, unable to reach the span. I attempted to cross the bridge - end to end. It was so crowded that after two hours, I only made it from the toll booths to mid span. The sag was visible. Could you imagine if the cables snapped, killing several hundred thousand? Even though the bridge held up fine, the bridge operators said they will NOT repeat such an event.

Whoah, Lesics would make anyone fall in love with physics. Brilliant production, perfectly explained. Free content can't get better than this.

Always fun to see computer animation of the bridge construction. Reminding us that the actual design and work was done in the 30’s

[hrithikgeorge]

Each procedure is so interesting that I'd love to watch entire videos explaining each step further. It's a marvellous structure!

[HotdogJuice]

I'm very interested in the work of those divers. I just can't wrap my mind around doing construction in those underwater conditions. Amazing!

Joseph Strauss was officially the Chief Engineer, based primarily on his long history of building drawbridges throughout the country. But for the GGB, Strauss had absolutely no involvement with its design. The suspension design was proposed by Leon Moisseiff, a Latvian immigrant who had been involved on other large suspension bridges in New York, and it was he who had the idea of an elegant suspension bridge. The real brains behind turning the concept into a well-designed structure, however, belongs entirely to Charles Ellis, a meticulous structural engineer who personally made all the static and dynamic load calculations, including solving some equations with 37 variables…all done without the benefit of computers. Strauss became so irritated with the attention Mr. Ellis was getting from the press and other engineers that Strauss canned him. It wasn’t until the 75th anniversary of the bridge’s completion in 2013 that a plaque was installed on the bridge to honor Charles Ellis as the true designer.

Great video presentation. They forgot to include the bridge road to be slightly arched, like an old arch bridge design. It may lessen the tension of the cables and reduce damage when the road deck steel expands. When the finger expansion has no more room for expansion, the steel road deck will push horizontally and may damage the two towers. When the road deck is slightly arched, it will just push up to lessen compression. The designers are very smart. It's a combination of an arch bridge and a suspension bridge.

I'm so honored to see this engineering introduce in this video. Thank you.

[Vizal]

It's astonishing how everyday things that surround you and that you normally don't think much about have such ingenious stories behind them!

[patraic]

Fun fact. The Golden Gate Bridge undergoes constant maintenance. There is a crew that works from one end of the bridge to the other. They repair and replace rusted out pieces and repaint as they go. This is a never ending loop. When they reach the end the crew goes back to the other side and begins the process all over again.

So many engineering challenges solved with master level solutions, and on top of that a great animation to explain it all. Excellence!
