I create weekly videos on:
- Helping civil and structural engineering students and graduates secure the best career opportunities in the structural engineering industry.
- Helping young structural engineers advance in their careers.
- Hints, tips, advice and my insights as a practicing structural engineer.
I'm a structural project manager in California with an undergraduate degree from Cal Poly Pomona and a master's degree from UC San Diego. My career so far has allowed me to design and manage various types of building structures, ranging from residential wood apartment buildings, commercial steel buildings, and concrete parking structures and towers.

My parents are both Taiwanese and we have went to taipei 101, MAYBE floor 88.something was beautiful! Didn't get to see the top floor but a world record 2015 fastest elevator made me yawn!
Hmm, I might check some buildings in my neighborhood that look like that.
The Grand Canyon isn’t the product of erosion. It was a product of this.
bro they made us disregard this film in my year 9 geography class
But what if it goes up and down ?
1700
They use the galvanized square steel💀💀💀💀💀
WTF Cares....? We have much bigger issues here in the US.....
you should watch hollywood more. they get it right.
Smartest dumb thing I’ve ever seen
It was my favorite movie but not anymore
Of course all surgeons would continue surgery during an earthquake, so this is very important.
Look at the Haiti earthquake and the splits caused there.
Sir, which structural analysis software is often used for you?
Ehm, the disastrous Hatay earthquake in Turkey in February 2023? Just as they show in the movies - ground split apart 1,5-2 meters (and even more!) wide open along the East Anatolian fault. Japanese high-magnitude earthquakes with ground buckled/asphalt split 1 meter wide? Unsubscribing. This scientist is a sham.
Couldn’t the plate theoretically seesaw over another plate and cause a split like that
Nah... the movie wasn't real?
The 2019 Ridgecrest earthquakes in CA actually did create small cracks like what was seen in the movie though.
Woah a movie wasn’t real?
Yeah it’s good they did research on this and created this. I hope they can do research on the impact of salt water in the air on buildings in Florida and the impact it has on both concrete and steel. Or is there a way to paint the steel or could they do a similar process they do to the frame of cars like the bath they go into.
What if you were to be on the ground away from buildings would it be safer than being inside a building?
Where you pay extra to be on the 2+ floor
When that thing comes down it’s gonna cause death and destruction for sure. And it’s up near the top? Genius. 😅
Very cool, cannot it survive a Chinese missile though, that's the real question
you know, i'm still not sure i want to be in a skyscraper during in an earthquake...... 😅
i love being structural engeer
Tell that to chinese builders who make skyscraper with polystyrene
Tofu buildings!!!!
I'd like to add that too much concrete reinforcement will cause a brittle failure mode. The key is to find just the right amount of rebar so it fails before the concrete, thus a ductile failure...
Great video! I should add if your building is not earthquake resistant, for example unreinforcrd masonry buildings, your best bet is to get out of the buidling if possible.
I just want to say thanks for the video! I love your content! 😁
They should produce electricity out of it
I think they got the idea from ancient pagodas that had a very heavy log hanging inside them
Wouldn't have guessed the answer alone, were I asked this question... 💀 (irony btw)
Let's hope it doesn't start resonating.
👷👍🙏
Damn, I wonder how did they got it up there
You ever drive home with a bowling ball in a Walmart sack? In the back of an SUV? eventually if you accelerate too fast the back door of the SUV allows the bowling ball to exit the vehicle.
Great video. A quick comment on Item #2 though. Strike-Slip earthquakes can create those types of valleys. Basically, it's caused by the fact that the fault is not a perfectly straight line. So, even though the overall movement is shear, deviations of the "straight line fault" cause some areas to act in tension separate. Those tension zone separations can create big valleys, although perhaps not as depicted by the San Andreas movie. This phenomenon is an all too familiar problem for tunnel engineers working in seismic areas where a buried valley in a fault zone can cause lots of issues when you thought the ground was supposed to be rock. Cheers.
Great to hear the prefix "licensed" to your name.
i'm a structural engineer in italy. we are in "Seismic zone" (nothing relation to japan or california, but we have a lot of old buikdings, heritage and cultural monument, small house and town). We have tons of small, rigid mansory building. we are "always" in the plateau spectrum. when i have to work with tall building (one in italy and a few around the world) wind and vibration is the "dominant load". tall building have long period, brb, massdamper, shock transmitter and so on. Liquify is a big problem also in our little italy. for the buildings but also for road and hills and montains hill. the most of italy is "not in plane" but we have towns, road, pipeline, poewrline and so son, in a clay slope. a lot of buildings have not pile foundation (except for venetian land, where i come from and where i live now, but for the majority building have superficial "fondation beam" or discrete superficial plinth/point support) 6:26 thanks. "earthquake safe buldings"...if you not have isolator or damper, means your life is safe, but the building gets damaged to dissipate energy. it is very complex to make customers and administrations understand it. if you do not want to install isolators or dampers, you must consider even severe damage to the structure.
That shit falls and starts to roll shit it’s gonna be ping pong game that you play on that flat machine
How tf did this ball got up there
when i first learned about hinges being created in the design of ductility in structures for earthquakes, my first reaction was "Wait, Am I reading this right?"
To be honest who tf looks at the floor and says “this is not perfect” oh wait I forgot some people have OCD and everything has to be perfect even if it’s the smallest visible crack, all I care about is if it works and functions as a floor
And if it falls?
Great job lord mat!
Great video! How do historical buildings and landmarks get retrofitted to meet modern earthquake safety standards without compromising their cultural significance?
We do everything we can to hide the retrofit work on the inside. And how we do depends on the building material. Like for San Francisco where they have those Victorian Houses with a garage underneath and for brick buildings and homes there are steel frames placed on the inside of the building. For concrete buildings we wrap the concrete in a special material to strengthen them and then paint over them. For special government and other institutional buildings like San Francisco City Hall and similar government buildings we tunnel under the foundations and put in dampening systems.
@@erichansen2860 To add to that - the Kearney Hall (civil engineering building) at Oregon State was originally an unreinforced masonry building. It was retrofit with a steel frame inside.
Very awesome
Imagine structural engineers without a computer? Moment distribution, three-moment equations, design of special connections, etc.
