You can go to Turkey (Kahramanmaras) to see which type of buildings are collapsed. After 7.8 then 7.4 then 6.8 earthquakes (and yes in a row) more then 1 million buildings are either damaged or collapsed. It's perfect way to examine the effects of earthquake and it's damage over types of building.

100% of failed buildings were concrete structures... Steel is better

Credible news sources carried stories re: corrupt building companies and city officials. Turkey has access to the same seismic building codes, through ICC, as we do. Just have to be followed. Of course, no building can stand up to some earthquakes. The point is to make them safer during and after.

@@skaford While I don't know how many buildings made of what collapsed, there are masonry buildings that have collapsed so you saying 100 percent were concrete isn't true. Steel is good in earthquakes sure but so are properly designed concrete buildings. There are many of them surviving fine. It is easy to mess up concrete buildings response to quakes with when inspections are poor. That contributes to many more collapses. Best materials for construction depends on the region and the loads that buildings are required to resist. Some points could be made in favor of steel or conrtete. Both can work.

Great video, very informative. Love the small scale demonstrations alongside the large scale footage. Greetings from a civil P.E. (but not structural). Small nitpick: 6:20 "in an earthquake-prone state, such as California or Seattle"

I wonder about wooden structures - it's not usually assumed to be earthquake prone, but locally here in Indonesia, a lot of them are prone to earthquakes. The usual strategy is just to brace them, but are there other stuff that does the same thing?

Bless the structural engineers who prevent the mass death of earthquakes, and the construction guys who build them to spec.

Also, I want to hear that what type of building. If older than 1990s commercial building, then also needs improvement for basic accessibility need ( so, open to employees, clients, etc) too. For residential building and hotel facilities, it could be no to some basic public accommodation like hallway and public restroom for "normal" residential buildings to 100 % accessibility building like senior citizens living apartments( private accessible bathrooms, not 28" 32" all doorways, and some private kitchen for independent living units only). Private owned residential like single family house it up to the owner what they need improvement in their own home like with or without physical disability, including Deafspaces, blind, autism friendly places, etc. Also, it can be in few to all hotels and "normally" family living units building.

Mat I am considering moving to the Philippines. If I build a house, it would likely be a cinderblock house like your third example. In new construction, how does one build a one or two story cinder block Masonry building on a slab and mitigate earthquakes? Not under building code obviously and in the Pacific ring of fire. Would a stucco or house wrap or 4x8 Styrofoam sheets glued to it help?

@gpdewitt 6 ай бұрын

International Code (ICC) includes seismic codes that cover this. Mostly has to do with steel reinforcement. The strongest structure I know of against both earthquake and wind is in Florida, built of steel and gunnite sprayed over an inflated bladder. Think upside down pool shaped like a dome. I imagine, but am not sure, that wind mitigation would apply in some or all of the Philippines due to typhoons. This is at least in part tying the roof rafters down against uplift with approved fasteners made for the purpose.

Couldn't exactly answer for the Philipines but in the neighboring states usually (if properly supervised) build a house using concrete reinforced column and concrete reinforced tie beam from ground floor to up. This makes the box very rigid, and earthquake while my crack the masonry walls, will not topple down the structure. Just have to re-plaster the walls or the cracked window panes afterwards tips: please make sure to have experienced certified architect or engineer (not just "a contractor company") to oversee the drawing proccess and the implementation of said drawing because builder often just "do it the way they usually do it" without any thought, which is to be expected considering most aren't educated or certified in building code.

Mat, which software do you prefer for analysis and design of structure, as well as for drafting and detailing?

Depends on the type of structure !

Ok. But what about a very complicated building which looks solid and is all these staircasing levels almost like a pyramid type thing? Like sort of i mean. Theres these penthouse like levels that narrow the building as it gets higher.

I like how he says "California and the modern world, implying California isn't in the modem world"

@doomguy9049 2 ай бұрын

That's true in many ways, though I think CA building codes probably hold up pretty well against those of other modern, earthquake prone states around the world.
