I saw this first hand in our city: A modern condo built by a prestigious developer had a soft-story collapse after a moderate earthquake 50 km away from Davao City, Philippines. Thank God, nobody was killed as the rest of the structure survived. The pancaked ground floor parking deck looked quite similar to your simulation.

Lots of buildings made in third world countries like Haiti, Turkey, Malaysia and Indonesia are guilty of these unsafe buildings. This is mainly due to the fact that steel comes in short supply when it comes to architecture. Most buildings only use stone or concrete to build their homes.
Turkey, California and some other places have this design , the lack of Shear walls and retrofitting... I really like your simulations... These are great visuals for earthquake engineering courses. I mean most of the universities have boring and flat visuals for Earthquake Engineering like ew...
Where I came from, in the USA, particularly the East Coast USA, we don't have many of these structures, if any. Though, I do know of some developing countries that DO use them, but for my parent's home country, which has A LOT of soft-story structures like Turkiye's, it is not prone to earthquakes unlike Turkiye though... Turkiye, along with Malaysia, Haiti, and others out there, having those structures is like a death trap during an earthquake, especially with what happened recently... I wonder how the recovery is going after 8 months...
One of the buildings on my town are like that , but its brick instead concrete , also there was only 1 powerful quake on my town , the Lisbon 1755 quake
@@videooyundunyasi its bc they dont need it. No building in Turkey has THAT much of a gap in the soft-floor. In older building it used to be larger but those buildings did have pillars in front of it. Since the 1975 quake code. No building can have that large of a gap. And after the 1999 the gap was even made smaller. Soft-stories are still allowed but i think the max is like 1mt from the front and 1mt from the back. My apartment was also like this. I was in it in the 7.8 Earthquake. Nothing really happened. I know it is substantioally weaker than a no soft story apartment but it is what it is. As long as you use good materials with good planning, buildings that have soft-stories can be resistant to earthquakes. Having a load-barring wall with concrete and iron will help a lot!
Soft story buildings cause pancake collapse, many buiodings in turkey were designed like this to coensate for growing population but they are usually very weak against earthquakes
I live in California near the San Andreas fault and my apartment is like this. Walls are made of cinder block. I live in level 1 as well. This is the best I could do because living here is expensive. If a major earthquake happens, I’m screwed 😞
I don't live in a soft-story structure like this, thankfully... But I'd imagine there are people out there (even some of my family members), that ARE living in one. Though, some of my family members where they live are not in a earthquake region even though where they live it is filled with soft-story buildings.
not gonna lie these type of apartment building were common in my country, what worse they are affordable which make more resident stay on unsafe building
The reason why these are common in some countries is bc there’s less material on the bottom meaning there very cheap cause it’s less concrete and most house use wood so there’s a 50/50 chance those columns are wood which is more dangerous the top heavy part damaged/week from little material will fall first

Turkiye has a LOT of this building its like all the apartments in Turkiye has this design and they dont even have like the small pillars for it

Hi, could I ask the name of this software? It is so cool.
Btw, can I also add foundations, or the ground cannot be modified?
I did not know that there was so much types of structures for buildings. Great video :D
I used to see these a lot in Minnesota but thankfully not in Seattle.
I'm not sure I want to hide in my car this time...
definitely not a good place to be in...
I learned that if you don’t reinforce a structure there will be a higher probability of collapse!
Indeed...
Now simulate it with columns rising the whole height and anchor the columns below ground as it would actually be.
I'm grateful that i don't live near any earthquake zones ( at least big ones )
Very nice simulation! That is why stilts would have to be deep, more like shearwalls, I guess

MINE IS LIKE THAT
Time to move

This building is very popular in Taiwan,
they can be problematic
unfortunately far too many buildings, specifically those built between the 50s & 80s were built like this
Hey, nice videos. Can you simulate, the İstanbul earthquake because we are waiting a big earthquake .
The reason why these are common in some countries is bc there’s less material on the bottom meaning there very cheap cause it’s less concrete and most house use wood so there’s a 50/50 chance those columns are wood which is more dangerous the top heavy part damaged/week from little material will fall first
I’m going off of things based off the top of my head
Bro said “this you?”
Or just don't build in an earthquake prone area.
Sliding beams are even worse . 01:45
I live in a shitty Soviet appartment and it would collapse in a few seconds
Hi
I'm the first
thanks for watching!
