From construction start (Jan 5th 1933) to opening (May 27th 1937) it took only 1603 days or just under 4years and 6months to complete, the first electronic scientific calculator was released by HP in 1972 (HP 35) so all structural analysis for the golden gate bridge was done with mechanical calculators and slide rules. Appreciate your AutoCAD and SOLIDWORKS.

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. Also, they show the traffic flowing in the wrong direction on the bridge. Our steering wheels are on the left in San Francisco!😂 Other than that, a very interesting video!

Yes, when I reached the 6:17 mark, I thought, "The cars are driving the wrong way!" (^: Digital effects might have been created in the UK or some other country where they drive on the left. If built today with polymers, it could be a cable-stayed bridge. But the people might revolt about that. 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.

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.

Fun fact for you: Though the GGB has a longer span between main towers, the Mackinac Bridge sports a total length 3 times that of the GGB(5 miles long). I have crossed a few times. Every time there is a maintenance crew working on the bridge. What they do is they paint the bridge every year, starting on one side, ending the year on the other side.

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.

@YDGFX canned: American slang for shitcanned, fired, thrown overboard... After Mr. Ellis completed all the specifications and load calcs, Strauss told Ellis to take a vacation. Then, a few days before he was due to return, Strauss sent him a telegram and told him to not bother returning. He replaced Ellis with some flunky engineer named Clifford Paine, who was credited as an engineer on the plaque on the South tower. Struass was a despicable glory hog, in my opinion.

We have a local bridge called “Kolekole Bridge” near Hilo, Hawaii. After 70 years it needed emergency repair and now there are steel supports along the side using the same metal as guard rails. It looks really ugly but does the job. Ever since it’s repair (a few months back) I’ve been in absolute awe like a foreign tourist “Look! The golden gate bridge!”

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.

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.

@Chris V. Four comments here: #1) I simply relayed what was said following the 50th anniversary. Maybe they'll change their mind. But I doubt it. They closed the bridge at something like 4 AM in preparation. As I started walking ~2 miles to the bridge, around 5AM, I was joined by ever growing streams of people. When I got to the bridge, the crowds were already unmanageably huge on both ends. They continued to grow throughout the morning. The bridge was supposed to be closed for just a couple hours. But if I remember right, it was not cleared by noon (long after I left). The lost revenue, potential liability, the added costs for crowd control, standby medical staff, etc., are all concerns, in addition to the crowds again becoming unmanageable. And then, there's the risk of terrorists. No one could possibly install and operate metal/weapons/explosive detectors sufficient to handle crowds of that size, where the venue is a temporarily closed, major highway. #2) Where did you obtain the 4000 lb/ft specification? That seems low given 6 lanes (collectively 62 feet wide) and two 10 foot wide pedestrian walkways. #3) Your math (36M lbs, 4000 lb/ft) implies the bridge is 9000 feet long.That is a distorted value because that includes the approach ramps on both sides, which are separately supported and run to ground at each end. And some of the elevated sections are directly supported by a truss construction to ground. The area of greatest concern is the main span, which is 4200 feet (16,800,000 lb, using your figure) 4) The bridge was visibly distorted - I saw it then and also knew just by the number of people packed into a space normally occupied by a car or truck and the space to the next vehicle's bumper, that it was loaded well beyond what it had ever previously experienced. If I were a bridge operator, I'd not want to exceed the average daily loading, which by my WAG (Wild Ass Guess) would allow less than half as many people. Furthermore, I'd need to ensure that they not be allowed to concentrate at one spot, such as mid span. One saving grace of the extreme overcrowding was that at least the bridge was uniformly overloaded - every square foot was occupied by pedestrians
Chris V.
Chris V. Aylar önce
@Gregory Parrott there’s no reason they shouldn’t. With some planning, you can control the amount of people that are on the bridge at any given moment. The bridge can support 4,000 lbs per foot of length before it starts to buckle, which means the bridge can hold nearly 36 million pounds of material, or a little over 200,000 average people (by American weight standards). The fact that the bridge saw 300,000 and barely buckled is a sign of how incredibly well engineered it is. Future planners can limit the amount of people on the bridge for its 100th anniversary to 100,000 at a time, with some ambulances and police forces along the way to maintain order. It would be a travesty not to celebrate its 100 year anniversary.

Most of the steel for the GGB was produced by the Bethlehem Steel Company at their various production plants in Pennsylvania and Maryland. Most of the steel was produced at their two steel plants in Pottstown near Philadelphia and Steelton next to Harrisburg, PA. The steel was produced, loaded up on ships and sent to San Francisco via the Panama Canal. In 1969, after my tour of duty in the Vietnam War, my stateside duty as at the 6th Army Aviation Detachment at Crissy Army Airfield in the Army base called The Presidio. My wife and I lived in Sausalito on the north side of the bridge and I worked at Crissy Airfield on the south side of the bridge. So for 17 months I drove across that beautiful bridge two times per day. While I was there I learned that the steel for the bridge was made in my home state of Pennsylvania. That was a cool fact to learn back in 1970. Our Aviation unit used the Crissy Army Airfield for it's base. We flew our twin engine Beechcraft airplanes on various missions and when landing we had to fly right over the GGB exactly in the center (from ocean to bay) and loop around the Bay and land into the wind which usually came in from the ocean (west to east). Those were great times for me and my wife and our daughter who was born in San Francisco. I wish I could be young again and relive those glorious days again...

Great video. Very informative. Chief Engineer Joseph Strauss did a great job. Our physics professor told us about the sagging when the bridge was first opened to the public. It was decided not to order people to leave for fear the order might cause a deadly stampede. Instead, access was limited to the bridge and anyone who left was not allowed to return. Eventually the crowd thinned out and the bridge stopped sagging.

Engineers can still design absolutely anything safely, to withstand static and dynamic loads under the most diverse circumstances, for many decades to come. But after that design phase the project is handed over to pencilpushers that'll take out any and all safety margins to cut costs. As a result, we (engineers) hardly ever get to design buildings and structures to *really* last anymore.... Unlike the Golden Gate Bridge, which has stood for 85 years already, and was designed to last, most newer projects have to last far shorter than that as they need to be economically viable - most buildings get torn down after they economically expire within 30 years at the max. Some falter well before that time, again due to beancounters that sit behind a desk only thinking of ways to save a bit of money - regardless of risk to health or even human lives. Engineering these huge projects used to be fun. We never looked to build another pyramid to stand tall for millennia, but buildings simply should last longer, and be more flexible, sustainable and durable than they are now.

My Grandfather (1890 - 1964) wrote a book on the engineering of the bridge contemporarily with its costruction. (1935). He was an engineer for the City of San Francisco. BTW. I don’t think they used roller compacted concrete. I inherited a small piece of one strand of the cable and splice from my mother. The Golden Gate Bridge will always be the standard for beautiful infrastructure. His book is still for sale at the gift shop.

@J S That sounds redundant to my ears, but there is probably some historical context in there somewhere.

@kindlin RC is also known as RCC (Reinforced Cement Concrete), they're the same thing

@Cadet Henderson I've been trying to figure out what he means by RCC. Usually it's just RC, and that's Reinforced Concrete; as in, RC Slab or RC Wall. I knew I had heard RCC before, and you're right, it's Roller Compacted Concrete, and that's definitely not how they made the GGB.

I've stumbled onto your videos 3 times, and only today realized they were all from the same channel. The last 2 times, I was in a hurry and distracted, and as a result, didn't investigate the channel more, even though I was very impressed with the videos. This time, I didn't make the same mistake, I clicked the Subscribe button immediately! I'm looking forward to checking out more of your older content, and any new material as well. I think a lot of people can benefit from your videos, whether they watch just out of curiosity and like to learn new things or better understand something they might have some knowledge of, or they have a need to learn more about something for some project.

having visited San Francisco for the first time, I had no idea there is an even bigger double storied bridge on the other side of the city that no one cares about!

Maybe I'm biased, but I don't understand how people complain about the fact that we don't make beautiful monuments anymore. Building something like this bridge is a far more impressive and inspiring feat of the human species.

@Paradoxica The moment some resource is found in space that can be mined with a reasonable ROI, or if some other country finds a military advantage in space, then we will see all the 1st world countries compete for dominance in space. The technology for landing on the moon was really based on the creation of intercontinental rockets, and the threat Americans felt by seeing the Soviets achieving dominance in that field before them.

@Paradoxica So it means when the Golden Gate bridge was built there was no capitalism in America? What then, socialism? Modern America can't build such structures because it had to admit that it needs white men to build. BLM and feminists won't do the work.

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.

What will happen to the monument to Joseph Stmuss remains to be seen, as 70 years after the fact, formal credit has finally been given to what many already knew - that the genius behind one of the greatest engineering feats of the 20rh century was Charles Ellis, a former University of lllinois civil engineering professor. While Strauss indeed was the brains, bravado and main booster behind the construction of rhe bridge, it was Ellis who developed the landmark's graceful form and worked thousands of mathematical calculations to build it.

Generally speaking, suspended cables are better approximated by hyperbolic functions not parabolic ones

That is why i as civil engineer really fall in love with these kind of mega structures. Only those who worked on structures know how they built it. For normal people it is just bridge to connect with each other but for us it is more than that it is our emotions, our commitment and love to our country.

@mastermind5421 False, depends at what exactly you do and in wich country. I get paid about equal with most engineers, I work more hours officially to be honest, but my friends that are engineers work a lot off the clock, even when they are home. Only disadvantage in my book is that my work is almost always in dusty environment and more physical

fun fact, because of the weathering it takes, the bridge is always in the process of being painted, by the time they have finished from one end to the other, they have to go back and start over again at beginning and paint it again. figure all those years and all those coats of paint. no wonder the main cables look like one solid cable. the painting also prevents rust from developing on the cables.
