    I was 13 years old when this bridge fell. My parents had to go out of town for a few days and left my younger sister and I with some close friends who lived in the same neighborhood. The man of the house was a truck driver and a good man. He had a delivery that this bridge was on his route. He ask me if I wanted to ride along with him and I was excited to ride in his big truck. The lady called my mother long distance to ask permission, but due to scheduling of my parents' return home, my mom said no. The truck driver would not be back before my parents arrived home. His truck was on the bridge when it fell and he lost his life. I was still at the house when his wife got the phone call and clearly remember her face going stone cold as she dropped the phone and fainted to the floor. That was a seriously troubled time for his family, especially that close to Christmas!!!

    Walter Carpenter was my high school Biology teacher. Later, I considered him a good friend. Whenever anyone greeted him and asked how he was doing, his reply was always: "Better Than I Deserve". As a resident of St. Marys for much of my life, I will always remember the original Hi Carpenter Bridge. And the new bridge which replaced the one which was closed, was opened to traffic the same week as I reported for active duty in the US Marine Corps, 1977. Mr. Walter Carpenter was an authority on local history and a good man. He is missed by family and friends.

      @John G I've designed things with much lower safety factors than 1.5. The company I work for has never had a structural failure, ever. We know what we're doing for one thing. But what is typical is that for instance if you double the design load then it makes sense to reduce the safety factor. It's all in what is meant by safety factor and which design parameters are defined before it's applied (like load). Per standards specs., materials have minimum strength requirements so there's a "safety factor" that's built in, but that is never used to my knowledge in a typical production type design environment. What is used is the minimum / guaranteed value. For instance what was said here was that they deigned it to twice the operating design load (which I'm guessing already has a safety factor built in). What was not mentioned was that typical values for design stress is 2/3 the minimum yield stress. Brittle fracture like this is based on the ultimate tensile stress which is typically about 2x yield stress (generally, but if you design to any stress you look it up specifically). So the what was said in this clip was for the laymans' consumption, but leads to misunderstandings. Safety factors are compounded and they only talked about how the design load was determined.
      There are also stress concentration factors associated with abrupt changes in geometry (like the hole). Those are not considered safety factors, so other factors of safety are stilled applied to that.
      I analyzed a pin in an engine lift that was used on a Chrysler production and they gave me the design loads and stated that the pin needed to a 10x safety factor on top of the design parameters (which may or may not have already included several safety factors)

      @Jive Patrol Yeah I'm actually very familiar with that bridge, having driven it many times in the passenger seat in my dad's cab over Freightliner in the 80s and then myself in the driver seat for the one year I had a learners permit myself. I still have a hard time believing that a 1.5X live load factor is sufficient. And while the chances of the bridge to ever be stacked from end to end with rigs that are all at max weight are extraordinarily slim, I can't help but very clearly remember my engineering professor drilling into us the fact that bridges now were all designed to 3.0X potential live load. Memory is a fickle and notoriously unreliable bitch though, so I'll have to do some of my own digging and see what I can find. If I do find anything of interest I'll post a link here for our mutual benefit. Thanks for your input and interest, regardless.

    My parents crossed the Silver Bridge just 1 day before it collapsed. I remember them saying that the swaying of the bridge just didn’t seem right and it really scared them. My dad stated that he would never cross that bridge again. Well, he was right on that one. I wonder if the ramps are still standing on either sides. I guess I need to make a trip to find out. Great video.

    This is a really great documentary. I like the no nonsense approach and the fact it isn't dumbed down but is still presented in a way that you don't have to be a structural engineer to understand what's going on. No propaganda, no bells and whistles, no unnecessary "pop art" graphics, just the story. This is a lost art.

    I was in the 9th grade and living in Parkersburg, West Virginia when the Silver Bridge collapsed. My Social Studies teacher brother was at a traffic light waiting to drive onto the bridge when it fell. One of my brother’s friends was a scuba diver and had to help bring up the bodies. This is a very good documentary of the incident. If you are a believer in the supernatural check out The Mothman Prophecies.

    I live about 30 miles from the this bridge. I remember hearing stories from the dive teams that went down to recover bodies and such. Many were getting stuck in the muddy muck on the bottom. One particular diver described seeing a catfish big enough to swallow a grown man just swimming back and forth in front of him. He stayed he poked at it with a hooked pole he was using and it just swam off.

    It's amazing how close to being safe this bridge was. The designer was right about the strength of the materials and the design. But because of the combination of water pooling, corrosion, and work hardened members the crack was created. If any of those three things had not been, it would have been fine. This goes to show that using a higher factor of safety may be overkill for the structure overall, but it comes in handy when you get these unlucky combinations of problems that are hard to predict and greatly weaken a single spot.

    I remember driving from Columbus, Ohio to Huntington AV a week or so after the Silver Bridge fell, and finding a tow or three mile backup at the Huntington Bridge, about forty miles from the Silver Bridge. Turned out everyone was waiting until the car ahead had gotten more than halfway over before accelerating so that there were only two or three cars on the bridge at a time. we were terrified.

    what a very informative and tragic discussion about this bridge failure. It seems that we always have to learn from accidents in order to make things better. I wish it were possible that we would engineer in safety protocols for things before they are built. I'm amazed at how the investigators were able to piece together the broken bridge and find the culprits responsible for the failure. Tremendous work in doing this without very much technology.It is a testament to people who died that every bridge now is inspected on a regular basis and they are maintained.

    did anyone catch this event in a movie called, "Moth Man"...? My grandmother lived on the Ohio side, in a house located on the hill facing the bridge at the time it fell. She told me her experience of the bridge falling. She was a house wife at the time, my grand father drove a greyhound bus to Chicago, and back everyday. She told me that she didn't see it break apart, but had a birds eye view of the horrific aftermath. She said she could not hold back tears then, and when she had told me about it in 1975. She had explained to me what is said here, that the people, the area, was so proud to have such a grad size bridge. How important it made them feel to what was happening in the US back then.

    I was 17 years old when the bridge fell. I was attending the old Barboursville High School as a senior. This happening just before the Christmas season left a saddened populace. This was the first really big event that made me realize that anything could and would happen with no regard for the people involved. I grew up when this happened and felt less than safe as a person on earth. This event, the assassination of John Kennedy, and the Marshall plane crash that destroyed the Marshall football team, cheerleaders, and loyal fans certainly made me realize that no one is ever safe, and fate, or whatever you want to call the randomization of events, was ever present and leering at all of us.

    It really makes you have immense respect for the designs that do work and do last.

    The older sister of this bridge, and one of these three already built in the world, (Hercílio Luz) in Florianópolis, Santa Catarina, Brazil, which is still standing, was recently restored. Cars went back on December 30, 2019, after 28 years banned due to cracking in one of the four eyebars support. Hercilio Luz may not have collapsed because it had four supporting eyebars, unlike Silver Brigde which had only two.

    I drove my mama across that bridge one day and remarked, "Mom, some day this old bridge will fall" as we experienced a trembling and scary swinging of it from side to side as we crossed. Mama replied, "No. They built this bridge too well." I crossed that bridge hundreds of times and was terrified each time. There was a traffic light on the WV side which caused the bridge to be loaded with cars and trucks for extended periods. I remember seeing the newspaper accounts after the fall with pictures of Christmas packages floating in the water. How haunting and sad that was.

    A factor of 1.5 is never enough for a bridge, in my opinion. It is enough if the loads are calculated accurately, if the loads are never increased, and if there are no design errors or defects in materials and workmanship, and no deterioration of the structure. But the factor of safety is what protects you against all those things.

    This is what happens when you make a suspension structure too rigid. The eyebar system enforced a side to side rigidity that concentrated stresses. The failure could have just as easily come from the small bolts that held the eyebar pin endcaps on. There were multiple design flaws in such a system, and why cable bridges are generally superior.

    • WardenWolf
      WardenWolf 9 ай бұрын

      @DD929 Basically, this. Cable bridges have a lot more flexibility and elasticity in their design. This design concentrated stress on the eyebar eyelets and the endcaps for the pins. Even if the eyebars didn't crack, sooner or later they would ream out and start allowing more angular displacement than intended, and this would lead to the eventual failure of the eyebar pin endcaps. This bridge was doomed to fail due to concentrated stresses and no way to inspect or repair it once assembled. There were multiple ways this could have and _would have_ eventually failed.

      And if those eyelets cracked at the holes, they would start to crack from the inside outward where they wouldnt be visible. The only way to inspect them is by diassembling them and inspecting them. It wouldnt matter what kind of material nor layers. If they crack, you wouldnt know it until it reached the outside of the eyelet, which would be too late.
      Am I right on that?

    15:10 Alloy steel has essentially the same elastic modulus (a measure of material stiffness) regardless of whether it's mild steel or high strength steel. The Silver Bridge used less steel because the steel was stronger, however this had the side effect of more deflection under load than a similar bridge built with more massive components. Hence the increased motion of the bridge felt by motorists compared to other suspension bridges.

    Very interesting. I've worked a lot on cars and most bolts on them are high strength steel, and some aren't, And I'm always shocked to see how fast the higher steel grades rust. Apparently they molecular structure, due to increased carbon is more brittle and more sensitive to corrosion. And bicycles, yes I am from the Netherlands, I've seen parts fail due to corrosion, of which most recently a crown tube from a front suspension fork, causing a concussion and tooth damage on a colleague of mine. He always rode this mountainbike with no front fender, and the water, which is often salt here in the winter to prevent icy roads, was splattering way up this tube and that caused it to rust out from the inside out.

    That steel they used was so brittle, it is unbelievable! Makes you wonder. It looks like they did exactly the same that they did with the rivets of the Titanic in the day: they added (sort of coarsely milled) SLAG in the iron (and yes those rivets furthermore were made from a mixture of iron and steel, whilst for the bow section of the Titanic they used even weaker rivets that only contained soft iron) which was one of the decisive factors with the sinking of that ship*. That slag that was put into those rivets (and in high levels) was a result of both material shortages and cost cutting, which resulted in the wharf obtaining those rivets from less reputable foundries that likely put in to to dozens of percents of slag to save on steel and iron. And worst of all was that by times rather big chunks of slag made it into the final product without further ado, which made them utterly unreliable and prone to failing! Now when we take a look at the place of the break in the bridge part(s), we see a very comparable, rough surface. It looked much more like the surface of any randomly chosen piece of hard rock on a mountain side, it out showing a very irregular surface (with lots of 'relief') of which the structure looks sand-like. And THAT is precisely what the most brittle iron by imaginable looks like. Note, this is NOT something that looks like steel AT ALL, it is IRON, and its appearance has all the hallmarks of CAST IRON - which is KNOWN for being the most brittle form of the type of metal that can be made, will BREAK when overstressed, lacks ANY flexibility, and contains an up to ten times higher percentage of added carbon than any other form of iron or steel. It is so hard it practicality will not rust. It is not impact resistant and has a tendency to break. Among its limited number of applications are ship boulders (present on the ship to make it possible to use mooring ropes, that also are used to stop the ship moving when required, and to keep it in position in waterlocks: of course the ropes won't harm the cast iron: they don't smash into it). ANYWAY, these bridge parts look EXACTLY like that - and as I explained, that means that no-one of the specifications of those parts met those that were required. Now if course casting can be done in many ways, it does not NEED to involve a high level of added carbon (or much worse still, added slag, which will not integrate structurally in the steel at all, is incomparably more course and every price of it once in can be seen as a hollow up spot, as the slag has nor adds ANY strength to the steel). And even when (initially) cast, the steel can still be rolled after, which (in combination with a tiny little bit of carbon instead of a whole lot) will give it the tremendous strength, flexibility, structural integrity, yes reliability of STEEL, and in combination with sight reheating will relieve it of (its) internal stress - that treatment allows the molecules the material consists of to rearrange into neatly organised, regular, grid-like structures. Only when ROLLED iron will actually become steel that has such highly valuable characteristics, tremendously strong, maximally consistent (without ANY voids even when checked on nano-scale), flexible AND impact resistant, and ALSO pretty much rust proof - especially in internally ~ in other words, high quality all around. What we see was used as parts to hang this bridge deck from, that was precisely the opposite. I have just described what it looks like she what it occurs to be, and what I would be enticed to call this, resuming, is nothing short of an ABOMINATION. It must have been a local foundry that not only lacked any ACTUAL know-how and professionalism, but that on top of that was allowed to go completely unchecked, with all the rest of the folk working on the project thinking these were quality parts with specific characteristics purely on their say-so (something that rings through even to this very day, one can notice when paying attention to the - inadequate - words STILL used to describe these parts AND actual critical and independent thoughts on the matter or any ADEQUATE description thereof STILL being missing even today!) so all of that reeks of politics, hidden interests and possibly budgets that were plundered.
    *Another decisive shortcoming had to do with the actual design of the ship that were severely flawed, untested, and only based on baseless assumptions: the ship was thought to have been made 'unsinkable' be cause it contained a whole series of supposedly watertight compartments. Those compartments however were not actually shaped like separate, independent, fully enclosed, water- and pressureproof spaces big enough to allow the ship to stay afloat even in a worst case scenario when SOME of those compartments would be breached, no, they merely consisted of partitions that only reached to a certain height and were open on the top. When the ship struck an iceberg the water that gushed in simply flowed over those barriers, quickly filling compartment after compartment.
