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.

While I am unaware of any deaths, I did see a paramedic team try to take someone out on a stretcher. People did their best to get out of the way, but it was dismally slow. Bridge operators and the city of S.F. can't risk another 'open house' on the span. Maybe they'd close it for a televised parade - like the Thanksgiving Macy's parade down Fifth avenue. The center would be cordoned off to pedestrians, but a long stretch of the roadway beyond either side of the bridge is also closed to traffic. This enable all attendees yo view the parade.

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.

It's mainly to avoid 'slump' when the load is very heavy. It becomes level when maximum load is on it.......except when 300K people were on in. Slump of 6 meters is huge, but it didn't apparently crack! (I would LOVE to know the concrete mix and steel usage that held w/o cracks). Along with this bridge, the Empire State Building is on the list of top 7 (ASCE) civil engineering wonders of the world. The ESP was built, and open for business in just 14-1/2 months, during the depression, followed by W2....leaving the owners with no profit until early 1950's.

@@jeremysmith9694 The designer is smart. I know there's no wind tunnel that time to simulate the wind effect. Maybe I am wrong. The steel truss structure below the road prevents swaying when there’s a high wind. The wind easily passes through and less drag. Remember the Tacoma Narrow Bridge collapse due to high winds? When they rebuilt the bridge, it was almost the same as the Golden Gate Bridge truss (under the road) and less swaying during high wind. Sometime in 2021 when I was in San Francisco VA Hospital, I could hear a high pitch sound coming from the Golden Gate Bridge area. There was a high wind that day. When I passed the Golden Gate that same day, I could hear the bridge was screaming. I am positive the neighborhood is not happy. I heard when they fixed the railing sometime in 2020, they can hear the high pitch sound during high winds. I am not sure if they already fixed it.

They started painting it 86 years ago and have never finished because by the time the last part is painted the first part needs paint again. Imagine being a professional painter and spending your entire career painting only one structure.

Additional facts: At the time of the Golden Gate Bridge's construction, no steelworks on the West Coast could produce components large enough to construct the towers, so they were shipped via the recently finished Panama Canal from the East Coast (New York specifically I belive) The Red color originally was to be a temporary coat to protect the bridge while a final color could be chosen (the navy suggested yellow/black stripes for visibility reasons) but it was stuck with as the locals were fond of it The Bridge was constructed with an unprecedented (for the time) emphasis on worker safety, to the point as far as I'm aware there was only one fatal accident during construction.

They give Strauss far too much credit here (a common mistake)! Strauss did come up with the concept of bridging the golden gate, and was its chief promoter, a herculean task in itself! However, he primarily designed cantilever bridges and did not have the engineering experience to create the suspension bridge that was built. Charles A. Ellis was the primary engineer.

Or they could make it with lighter materials and have the same design, but towers closer to the shore to save money. It costs a lot to maintain this bridge so they might replace it some day.

A well engineered vlog that I have seen on civil engineering. Thank You for sharing it.

This might seem crazy but I actually cried appreciating the genius of human engineering. A lot really do go underappreciated! Your videos make me appreciate life a lot more.

What an amazing video describing this engineering marvel. Thanks for the incredible 3D work you did, it brought it to life.

Golden Gate was interesting but what about The Howrah Bridge of Kolkata? It was also a really incredible project.

Chenab bridge too looks fascinating.

Got the opportunity to see and cross the Golden Gate Bridge when I was in San Francisco some years back. It's was truly a sight to behold

Thank you for the animation, it helped visualize things rather than just saying words and plain picture

No doubt it is an engineering marvel. This makes me proud to be a Civil engineer student. This motivates me to study harder. While studying I just imagine that this 5 page numerical defines the lives of thousands of people who are going to use it.

Wow. I didn't know the bridge was such an impressive engineering feat. It deserves its place among the Wonders of the (modern) World. And they did all of this without computers.

Wonderful, well calculated basics on this Golden gate bridge. Great info for civil engineers and a great experience for the passengers on this bridge. Alexander, lndia.

This is the amazing video i have seen in a long time. And also hats off to the engineer behind the golden gate bridge "The Joseph Strauss"

The foundation part is really intriguing. Its unbelievable what humans can achieve.

Watching this video and gaining such information makes me even more happier being a civil engineer.😊

Another interesting engineering tidbit involves the bridge's south anchorage. Upon site inspection, Strauss realized that the Civil War-era Fort Point stood on where he had planned to build the south anchorage for the suspension cables. Wanting to preserve the fort's architecture, he redesigned the south anchorage, incorporating an arch structure so that the bridge could pass over the fort, thereby preserving it. The redesign also moved the suspension anchorages further to the south. (Note: it's also been hinted that preserving the fort saved the Golden Gate Bridge district a ton of money. The bridge was being built on US Army property -- the Presidio to the south and Fort Baker to the north. As part of the agreement with the Army to build the bridge, the bridge district was required to compensate the Army for any property they had to demolish during construction. Needless to say, demolishing old Fort Point would have been quite costly for the project.)

Absolutely superb.

I was always waiting for a civil Engineering video since I am a Civil Engineering student. Thankyou lesics for this. Joseph Baermann Strauss was a great Engineer. Respect to him 🙏.

No - Strauss was not the actual engineer of this bridge. He has credit bestowed upon him that he does not deserve. Had it not been for the work of Charles Ellis, the bridge would have been nothing but a twinkle in Strauss's eye. Ellis did all the stress calculations, and made many engineering decisions that Strauss got credit for. Ellis was a distinguished mathematician and structural engineer; Professor of Engineering at the University of Illinois. Ellis Hall, on the Engineering campus, was named for him. There would be no bridge without his work.

It was Charles Ellis who did this. Strauss is a glory hogger.

Man, this is really impressive how they thought of all these problems to fix to build such a bridge

this is becoming my favorite channel on yt. thank you guys so much for the work that you do! these videos are incredible and honestly so well-made that it's kinda shocking. please keep making these!

Man, you are brilliant. One of the best KZread channels. Not just my grandson (who loves everything engineering) enjoyed the video, but I also learned a LOT of interesting things.

it wasn't just Joseph Strauss, there was a talented team of engineers and architects involved in this, give credit where it's due.

This bridge is incredible 😮… thx for the video.

A master piece of engineering and architectural design

Another great childrens education vid from Lesics! My 4 yr old loves these!

Amazing engineering. Thank you for your clever & clear video 🎉

You also forgot to mention that the bridge deck isn't just straight horizontal as many think. The deck actually arches upward some to the middle of the bridge. One is because the Earth's not flat. So over long distances especially with water that to has an arch to it so if the bridge was built straight across the middle part would actually hang lower to the water. Also alot of times when you see bridges even short ones you will notice it has a slight arch to it. This is bc a bridge with an arch it much stronger then one that's just straight across bc it's arched it presses it self together due to gravity which causes a downward pressure that keeps it in place. Straight bridges doesn't have that and that downward force is still there and without the curve to help balance the downward force it can continue to keep pressuring downward (sagging)until the other supports fail.

Your first reason is just rubbish. The length of the bridge isnt long enough to consider the earth curvature in the design. The second reason is solid from engineering point of view.

I believe the paint is Red Oxide. A special rust resistant paint. The paint is very effective normally but in a harsh sea-air environment, it needs to be re-applied regularly. I believe the bridge has full time painters, the painting never ends.

Arch upwards transfers load to compressive force which concrete can bear. Not tensile force. That is why bridge fesvk is arched upward.

@@tubester4567 you are right. I saw on a documentary once that the painters(I think like four guys) take a whole year to paint, then at the end of the year, they start all over again. Haha

How brave the people are when building the concrete base is crazy. When sailing small boats around the base, swells can get to where it’s like sailing up a hill.

Man this video is kinda sparking the engineering/math loving side of my brain that I let kinda die over recent years. Super super cool stuff. And it’s absolutely incredible that this even happened. Like imagine the SIZE of the team that there needs to be working on this. All with the same goal in mind, all working in tandem to create something bigger than themselves. Absolutely incredible

Great video and amazing they pulled this off given the technology available

9:20 You can learn this section at home by hanging heavy pictures or mirrors with picture wire. The weight of the load is always the same but the tension in the cable depends on how it is oriented. Vertical would be supporting the weight fully. But with added angle, only a portion of the tension is holding the vertical load weight.
