Hello guys. I'm an earthquake engineer. This is a little different from a real earthquake simulation because earthquake moves the buildings in 3 directions but this table only moves in 1 direction. Also earthquakes have many different frequencies happening randomly not increasing gradually. The third difference is seismic isolators must have a returning mechanism that means after the building is moved, it tries to bring it back to its original location. The four marbles used couldn't bring the building back to center and it caused the shake table hitting the foundation. Anyways it was really fun to watch. Thank you 😊
I once had an idea about a wind mill that didn't use the wind Pressure vibrations when I realized that. A buildings foot print hydraulic centered in xyz as for the vibrations they are absorbed by a cushion that turns vibrations to elastic When we say earth quake we say rapid Omnidirectional displacement distance traveled energy over time. Which means you move the way the quake moves you instantly
Since the rpms of the motor are constantly rising, there couldn't be a harmonic motion for more than a split second. The only reason the tower is stable is because it's standing on marbles, which let the tower roll free in the oversized shaking base. Clever solution surely. But no harmonic motion is taking place here.

We did something like this at my school where they were statically tested with weights. Probably a little cheaper to run, though you still have to buy the wood.
To be fair, your school probably had the budget. Your teacher just said “not my job”. You might not have the budget to buy a pre-made one, but a motor is like $5 and the woodworking class has the materials to make one. It’s not rocket science, between your science teacher and shop teacher they’d have known how to make one for $5 and some change.

That movement that finally dropped it down was probably a magnitude 9+ earthquake comparable, since it took way too much movement. That means they built that building pretty good.
At the point near the end they were say 15 seconds before it dropped. You Xanax here then say ttat. It could have gotten as close. As close as 18. How devastating that would be anywhere, especially in a big city
Science is cool. Props to wherever this school is at, and good job to the teacher. These students are totally invested and interested to the max. It’s good seeing that this type of classroom setting is still alive and well
What a good program. We had a class similar to this in middle school. Our shop class. We built rockets and shot them off, turned wood on a lathe, played MS flight simulator, there was like 6 stations to get through 1 semester. One of my favorite times in school other than band.
Yeah.... I'm fairly sure the base has room to move around in, so the tower is just staying in the middle because of the friction keeping it centered. I say this because it makes sporadic movements and loud snaps when the tower does hit the plate Edit: seeing the marbles makes me think this was the plan all along, and everybody probably had the same opportunity to use a similar solution. So while the test is a little flawed, it is the same for everybody However, there are definitely no harmonics going on. This would happen at a certain rpm of the shaker motor and only be stable at that setting. Since the vibration speed is constantly rising, there can't be a stable state for more than a split second. And the tower is clearly stable throughout a large range of the rpms.
@@TomCat13461 Nope. Mechanical resonance is where the different movements line up due to the frequency and amplify these movements. Usually leading to failure. The phenomenon in this experiment would be called harmonic frequency. Where the movements cancel each other out. But that's also not exactly what is happening. The tower is loose in the base and rolling on marbles. There is barely any force transfered to the tower because it can freely roll. Technically the friction of the marbles have a achieved a stable state which can be described as harmonic, since they are moving themselves left and right at the same rate as the vibrating platform. Causing the tower to remain in place. Until at one point, the tower is moving in 1 direction fast enough to collide with the return stroke of the shaking base. Causing a large shock which breaks the tower.
You mean when the structure lost contact with the mechanism..? Cuz it wasn’t being touched by either side and was instead perfectly sliding without contact.
I remember being on the couch for my one and only earthquake, happened when I was a kid. The couch just slid from the middle suddenly to slam into one wall, then the other, then back to the first. Honestly remember it being kinda fun cause I was too young to really know the danger
And in the 10,000 aftershocks it can roll from other directions or just shake. After a while anything under a 5 doesn't really register but anything above you get amazingly good at predicting it's strength. Then you think you're over it and you're sitting on a sofa and someone walks behind it... cue freakout from the vibrations.
@@CJ-im2uu that's why idk why these engineeres thought that earthquake moves side to side. Looks like most of them didn't experience the real deal earthquake
Yup, was eating a meal with a neighbor and my mom on Easter Sunday a few years back. Felt like I was on a damn boat, but we were sitting at the table, in a house, on a concrete slab. In certain areas and at high magnitudes, the ground actually "liquefies" and behaves like a fluid, with soil and vegetation rippling up and down like choppy waves on the ocean. Earthquakes are no joke, it's a massive amount of energy and stress being released.
@@SCP-79.There have been many times I have felt the same as a U.S. citizen. It’s definitely dicey right now with everything going on, but invading Afghanistan for non-existent “weapons of mass destruction” and the drawn out war in Iraq was even worse.

@@uggsxx9155 To be fair, both of you are right and wrong. If you're in a building during ever-increasing seismic activity and all of the sudden the building simply *stops* moving, then chances are 50/05 between the building collapsing and probably killing you regardless of where you stand, or gently start moving again and slowly stop as the earthquake fades away...

@AL-xx2dw resonant frequency is where the movement of the table is going through the structure, bouncing off the top and coming back. The frequencies overlap and either build on top of eachother or subtract from eachother in what is called either constructive or destructive superposition. As the frequency or speed of the table increases the system goes from constructive to destructive and back. When the system is in constructive superposition the force of the waves traveling through it it doubled so the structure falls. This is the reason soldiers can't march over bridges or they will fall
I was taking bout the frequency of the object that matched the frequency of the earthquake which is why the structure seemed to stop moving at one point.
@@oscarhughes5532 bro wtf, you explained resonance frequency when the "what" comment was referring to the fact that why tf else would they be doing this experiment if thats NOT what they were learning in class
I worked for a company that makes earthquake proof houses in Japan. These students got the concept of what I learned from the blueprints. Great job teacher! 👍🏻
Wait so it's true? My hubby went to Japan and he sent me some pics of the bridges how they where on like swivels or something? How or what are those? He asked and they just said earthquake but how are they more resistant if you don't mind explaining
The marbles under the structure mimicked a "base isolation" seismic system. The structure is isolated from a lot of the ground motion. Super effective and typically used for critical structures like hospitals or high rise buildings. Cool model!
@@tristintaylor7999 Not in this case. Since the machine only shakes in one direction, you theoretically only need bracing parallel to the shaking to resist those forces (which it has on both walls for the full height of the structure) If you look closely, the structure failed at the base connection of the rightmost column. The braced frame along the height of the structure remained intact as it toppled over. So it did it’s job.
For everyone wondering why it stopped moving, it's called antiresonance. Soon after, it started shaking hard and broke, this is called a resonance. The values of antiresonances and resonances can be calculated before building the building and you have to consider them when designing the skyscrapers etc.
I did this same thing in my architecture and engineering class in high school. With buildings and bridges. Some of the best memories I have of high school.
I mean it seems like a fun project tbh. Like I know I would've absolutely LOVED this kind of lesson. Not only does it teach but also provides entertainment at the same time. Which makes kids focus more on the lesson as they're genuinely interested in it
Best design Ive seen. The building actually got more stable as the shaking continues until it reached the breaking point and it happened on the foundation not because it was top heavy. Very impressive
It was just a clever use of marbles, the foundation was placed on top of them, so that it would roll back and forth and remain stable instead of shaking.
@@kekw35 Ironically, Loki and Thor are not brothers. However, Thor did have 3 brothers, but their names are Baldr, Vidarr and Vali. Vidarr is destined to avenge his father and kill Fenrir, who in turn has 2 brothers and 1 sister (Sleipnir, Jörmungandr and Hel, though Loki was actually the mother of Sleipnir so not sure if that counts). Vidarr will also survive Ragnarök
My college roommates were Architecture students. They said some students were so overworked and tired that when their models failed tests they would weep.
@@willhenry3011 Nah they aren’t just ball bearings lmao. They are giant balls made of steel or concrete. They weighs anywhere from 300 to 800 tons which just a lil bigger than most ball bearings. And they are usually suspended in the building using springs and pistons. It’s not like the marbles shown in the video, like the original comment said they are counterweights. They are in the top of skyscrapers and sway in the opposite direction of forces to negate them and prevent resonance, reduce motion sickness, and counter storm winds.
I have studied that shock absorbers in form of giant rubber cylinders can be used in foundation of small house to make it earthquake resistant to greater degree.
I love when teachers do things like this with their students. My daughter's teachers all do fun, engaging things with the students and her grades have really improved because she's interested.
That's like when my science class did crash test cars, and I built mine with a rear-facing back seat. From passengers did mediocre, rear passengers had the best score in the class.
You guys must have went to some schools with funding, I went to a predominantly black school and we rarely ever did physical experiments, it was always on some bullshit website with simulations, even then we never did this one. They never taught us anything of meaning
I remember taking STEM classes in high school a couple years back. It never stopped amazing me seeing the ideas that come into the minds of people who want to be there. School should be more about finding the stuff that actually interests you. I knew so many kids that would have loved to take the classes I did. School needs to become less of a place where everybody goes to learn the same things, and more of a place to ignite and harbor that creative spark all kids have growing up but gets taught out of them come late elementary school.
yes, I watch old japanese TV show (about old home renovation) and many of their house built with that diagonal struts in the walls. That struts the main core how the building stabilize during earthquake. the simple one is using a huge diagonal beam from a corner to corner, but if the house located on more prone to had earthquake, then the other corner will add simillar mini beam on the untouch corner, and they put is rubber cushioning in the corner, act like shock absorber & help maintain pendulum effect to stabilize the whole building. taller building (taller than 3 floors) they will put a real rubber shock absorber & some cushoning under each pillar, allow the building wobble steadily along with earthquake frequency. the key for enginering (i think) to this problem is to understand how not only neutralize the wobble, but also how allow the building move along to mitigate the earthquake vibration. Japan Tohoku Eartquake (that cause Nuclear Powerplant exploded) is considered scary, as the land not only move side to side, but also ups & down in all directions, which very damaging, especially if the building not cushion properly.
@@JustinWayneDawgThis is common braced framing? Hes just saying its built well and lists his credibility as someone who regulary contructs these structures at full scale.

The series and positions of near failure that structure survived is a fascinating lesson. Bravo
The laws of inertia, physics, kinetic and potential energy sources.
That movement that finally dropped it down was probably a magnitude 9+ earthquake comparable, since it took way too much movement. That means they built that building pretty good.
Yup, we can't escape God smite... That's already good for people to escape from building while it collapse
At the point near the end they were say 15 seconds before it dropped. You Xanax here then say ttat. It could have gotten as close. As close as 18. How devastating that would be anywhere, especially in a big city

You kids did a great job! This really had them engaged!
What a good program. We had a class similar to this in middle school. Our shop class. We built rockets and shot them off, turned wood on a lathe, played MS flight simulator, there was like 6 stations to get through 1 semester. One of my favorite times in school other than band.
Luv how engaged the students are, wish school was more fun like this. Imagine how many more amazing minds and discoveries we'd have.
Funding matters
The moment it went still is the exact moment the vibrations synchronized with the structure’s framework
Yeah.... I'm fairly sure the base has room to move around in, so the tower is just staying in the middle because of the friction keeping it centered.
I say this because it makes sporadic movements and loud snaps when the tower does hit the plate
Edit: seeing the marbles makes me think this was the plan all along, and everybody probably had the same opportunity to use a similar solution. So while the test is a little flawed, it is the same for everybody
However, there are definitely no harmonics going on. This would happen at a certain rpm of the shaker motor and only be stable at that setting. Since the vibration speed is constantly rising, there can't be a stable state for more than a split second. And the tower is clearly stable throughout a large range of the rpms.
Resonant frequency.
@@TomCat13461 Nope. Mechanical resonance is where the different movements line up due to the frequency and amplify these movements. Usually leading to failure. The phenomenon in this experiment would be called harmonic frequency. Where the movements cancel each other out.
But that's also not exactly what is happening. The tower is loose in the base and rolling on marbles. There is barely any force transfered to the tower because it can freely roll.
Technically the friction of the marbles have a achieved a stable state which can be described as harmonic, since they are moving themselves left and right at the same rate as the vibrating platform. Causing the tower to remain in place.
Until at one point, the tower is moving in 1 direction fast enough to collide with the return stroke of the shaking base. Causing a large shock which breaks the tower.
@@TomCat13461looks like somebody watched to much MatPat
You mean when the structure lost contact with the mechanism..? Cuz it wasn’t being touched by either side and was instead perfectly sliding without contact.
If you've been in a 7+ earthquake, you'd feel that the land does move up and down like a seesaw
I remember being on the couch for my one and only earthquake, happened when I was a kid. The couch just slid from the middle suddenly to slam into one wall, then the other, then back to the first. Honestly remember it being kinda fun cause I was too young to really know the danger
And in the 10,000 aftershocks it can roll from other directions or just shake. After a while anything under a 5 doesn't really register but anything above you get amazingly good at predicting it's strength. Then you think you're over it and you're sitting on a sofa and someone walks behind it... cue freakout from the vibrations.
I was in the Loma Prieta. There were times when it felt up and down and side to side.
@@CJ-im2uu that's why idk why these engineeres thought that earthquake moves side to side. Looks like most of them didn't experience the real deal earthquake
Yup, was eating a meal with a neighbor and my mom on Easter Sunday a few years back. Felt like I was on a damn boat, but we were sitting at the table, in a house, on a concrete slab.
In certain areas and at high magnitudes, the ground actually "liquefies" and behaves like a fluid, with soil and vegetation rippling up and down like choppy waves on the ocean. Earthquakes are no joke, it's a massive amount of energy and stress being released.
That random "No freaking Shot!" - "What?!" combo from the off when it hits harmonic motions needs meme status.
This was one of my favorite classes in school. They called it problem-solving and you would get up in little groups and do stuff like this.
i wish they incorporated more active learning lessons like these in school, they were the best lessons and the ones you actually remembered

To go out and get hit with possibly collapsing buildings and falling debris?
@@uggsxx9155 To be fair, both of you are right and wrong. If you're in a building during ever-increasing seismic activity and all of the sudden the building simply *stops* moving, then chances are 50/05 between the building collapsing and probably killing you regardless of where you stand, or gently start moving again and slowly stop as the earthquake fades away...

These kids got a lesson in frequency and their teacher didn't even know.
......what
@AL-xx2dw resonant frequency is where the movement of the table is going through the structure, bouncing off the top and coming back. The frequencies overlap and either build on top of eachother or subtract from eachother in what is called either constructive or destructive superposition. As the frequency or speed of the table increases the system goes from constructive to destructive and back. When the system is in constructive superposition the force of the waves traveling through it it doubled so the structure falls. This is the reason soldiers can't march over bridges or they will fall
I was taking bout the frequency of the object that matched the frequency of the earthquake which is why the structure seemed to stop moving at one point.
@ninobrown9202 yeah but you said the teacher didn't even know it... that's apart of lesson they're being taught... by the teacher.
@@oscarhughes5532 bro wtf, you explained resonance frequency when the "what" comment was referring to the fact that why tf else would they be doing this experiment if thats NOT what they were learning in class

I brought in super glue to my class and everyone thought I fr killed it
I worked for a company that makes earthquake proof houses in Japan. These students got the concept of what I learned from the blueprints. Great job teacher! 👍🏻
Wait so it's true? My hubby went to Japan and he sent me some pics of the bridges how they where on like swivels or something? How or what are those? He asked and they just said earthquake but how are they more resistant if you don't mind explaining
So... Marbles as footings? Got it.
Am I correct in thinking that in Japan, when they build skyscrapers. They put huge springs in the foundations??
You put ball bearings under the buildings?
You guys put balls in your buildings in japans foundation?
My teachers would’ve flipped if someone in class said frickin lol
The marbles under the structure mimicked a "base isolation" seismic system. The structure is isolated from a lot of the ground motion. Super effective and typically used for critical structures like hospitals or high rise buildings. Cool model!
Would it have benefited more from having the cross frame on all four sides instead of just two?
@@tristintaylor7999 Not in this case. Since the machine only shakes in one direction, you theoretically only need bracing parallel to the shaking to resist those forces (which it has on both walls for the full height of the structure)
If you look closely, the structure failed at the base connection of the rightmost column. The braced frame along the height of the structure remained intact as it toppled over. So it did it’s job.
In California this is basically required for svery building by law
In the case of a real structure, what would be used in place of the marbles?

@@deltaxiii7803 wtf is this comment
@@PK-ts8iz its me being sarcastic
For everyone wondering why it stopped moving, it's called antiresonance. Soon after, it started shaking hard and broke, this is called a resonance. The values of antiresonances and resonances can be calculated before building the building and you have to consider them when designing the skyscrapers etc.
no its becasue its sitting on marbles ie taking out 90%of any movement. when it speeds up its just engaging the marbles to take out near 100%

This is why tall buildings in earthquake zones have mechanical counter weights, preventing the resonant frequency from tearing itself apart.
@@willhenry3011 Nah they aren’t just ball bearings lmao. They are giant balls made of steel or concrete. They weighs anywhere from 300 to 800 tons which just a lil bigger than most ball bearings. And they are usually suspended in the building using springs and pistons. It’s not like the marbles shown in the video, like the original comment said they are counterweights. They are in the top of skyscrapers and sway in the opposite direction of forces to negate them and prevent resonance, reduce motion sickness, and counter storm winds.

You guys must have went to some schools with funding, I went to a predominantly black school and we rarely ever did physical experiments, it was always on some bullshit website with simulations, even then we never did this one. They never taught us anything of meaning
When the seismic oscillations hit the building’s natural resonance, it’s gravity time. … And way down we go.
I remember taking STEM classes in high school a couple years back. It never stopped amazing me seeing the ideas that come into the minds of people who want to be there. School should be more about finding the stuff that actually interests you. I knew so many kids that would have loved to take the classes I did. School needs to become less of a place where everybody goes to learn the same things, and more of a place to ignite and harbor that creative spark all kids have growing up but gets taught out of them come late elementary school.
Houses in Japan are built much like that model where the foundation is made to glide back and forth and the frame wobbles along.
Got to with how it is in Japan
every modern sky scraper
Old news bro
yes, I watch old japanese TV show (about old home renovation) and many of their house built with that diagonal struts in the walls. That struts the main core how the building stabilize during earthquake. the simple one is using a huge diagonal beam from a corner to corner, but if the house located on more prone to had earthquake, then the other corner will add simillar mini beam on the untouch corner, and they put is rubber cushioning in the corner, act like shock absorber & help maintain pendulum effect to stabilize the whole building.
taller building (taller than 3 floors) they will put a real rubber shock absorber & some cushoning under each pillar, allow the building wobble steadily along with earthquake frequency. the key for enginering (i think) to this problem is to understand how not only neutralize the wobble, but also how allow the building move along to mitigate the earthquake vibration. Japan Tohoku Eartquake (that cause Nuclear Powerplant exploded) is considered scary, as the land not only move side to side, but also ups & down in all directions, which very damaging, especially if the building not cushion properly.
