The Surfside Florida condo collapse made me recall watching some of the construction in Chiang Mai and China. It always shocked me how a dozen or more stories are supported by those spindly first floor columns that usually are within a parking area. The weight of the slab floors on each level add up to some huge numbers, and those columns have to support massive loads. I can't image they are earthquake-proof and would expect some of those buildings to collapse in an earthquake, especially with columns not being a constant concrete pour.
At any rate, this guy has some detailed information on the Surfside collapse some might find interesting. Even in this case, the number of columns is surprisingly small.
