Buildings in Earthquakes: Why do some fall and others don't? (educational)

[@Ciubowski]

This video deserves more views.

Great video! Explanation, graphics, and demo were all very clear. Shared with my family (3 generations) and everyone found it interesting. I love being able to better understand why some types of building are devastated by an earthquake while others remained standing.

Very well made video. Thanks to it, I learned that structures have a natural resonance frequency and how big of a difference it can make.

[@aashishp007]

The explanation has clarified all my doubts...Thanks a ton!!!!

[@valeriewedel2775]

Awesome video - thanks! Bringing this to my commercial construction drawing class.

On the Tacoma's Narrow bridge something called 'Vortex Shedding' added to the problem. I love this video though, so thank you for providing it.

[@ngwilliam5619]

Very clear demonstrations. Thx

[@NK-iy6if]

God bless you ! Thank you so much the video has been incredibly helpful.

[@ranjithalluri604]

Excellent

[@simantsoren1120]

I've learned a lot thanks

[@khangembamkumar7274]

It depends on rate of frequency... Great content 💯

[@haominghuang4990]

phenomenal, informative video

Who is here watching this video after the earthquakes in Turkey?

[@liboy9844]

But not much help if it boils down to luck on which building you’re in and what type of earthquake occurs.

wow amazing

[@wpegley]

Great video & thx.

[@mahendarreddy9862]

Very nice video

[@handedilhan]

Thank you

Doesn't the frequency & its amplitude change according to the size of the earthquake? Surely that ground & building structure plays a key role in general durability against collapses, but what about the shockwaves? Surely a magnitude & destruction power of say 5.5 and 7.4 earthquakes can't be the same, also depth is another factor.

[@mariannamakari9593]

They also change according to the types of soil that the wave meets on its way from the epicenter to the structure.

Super clear thnkss a lot

[@satishvenkata1214]

SUPERB SIR

[@itziamejia1360]

what would be the equation of resonance?

[@danielsmb2635]

It is the eigen value of the system; in this case the building system consisting of mass and stiffness…

[@AndrewNowacki]

Great video.

[@deepakchacko5585]

Superb

The most earthquake-resistant house in Japan is a wall-type RC house.

[@eeesss9593]

great great great one.

[@priyanshupatel2282]

GREAT

[@SunandGold]

Thank you!!!!

[@deemarrero9]

Amazing video, well explained and graphics.. very important to know this, since with all the damages Human Race it's been doing to mother earth 🌍 Earthquakes like those in Turkish it will happening more frequently in the whole word.

Thanks

who's here after the Ny Earthquake

[@georgen9755]

one wave cycle equals twenty one Hertz

I wanna be civil engineer
