There is no "atmospheric pressure and other technical parameters" problem. They will simply be too small to be used (apart for some mechanicals) and to contain an elevator shaft

Interesting that it's using the same floor slab shape that the CN Tower used in 1975.

Y-shaped floorplates are some of the most stable. Expect most future tallest towers to have them.

haha yeah i was surprised for a moment. it certainly is the easiest way to build tall it seems so, burj khalifa worked so building a taller tower seems to inherit it to build a stable extremely tall tower, but the conventional buildings are creeping up and getting closer as well though, seeing that Zhongnan Center is extremely tall and massive as well but it seems like the candidates for a worlds tallest will do well if they go with this structure, seems reasonable that developpers are also more likely to invest in something that already was built in a similar way. when qianhai was first announced to maybe feature a landmark tower of 800m, the only model we ever got of it seemed also to be a burj khalifa style building. So i think he has a point, it is just the cheapest way currently to get safely tall i guess. if something like sky city would ever get built that might change again though, only the future will tell, might be a phase with burj khalifa and kingdom tower as it was in the 70s with extremely tall boxes getting the worlds tallest titles.

Agree. 70s record holders were more than just about the height as are chinese megatalls that's why they all don't have burj like shape. That shape is perfect for impressive but still pretty much statues like burj or kt but not for practical buildings.

What's practical depends on the primarily use of the tower. BK is perfect for its primarily use of hotel and residences, while a primarily office building can be made massive.

The top third is mostly inhabitated (the entire top fourth)

Yeah, but I mean out of the top 10 tallest Burj is the only one with a y-shaped plate. Many new tall proposals have them.

I'm curious which one? i can only name kingdom tower (and Ryugyong Hotel if you count old ones too ). There is significant difference between y-shaped plate, and y-shaped core though. Of the later I can name two proposals which began construction but none of them have extremely tapering shape with huge footprint and pointy top. Also both have lots of usable space compared to burj or kt. But they only have y-shaped core with usable space between the "wings". Basically they are different in almost any way from burj desing.

But still the majority of megatals out there are square core+megacollumns designs including Zhongnan Center which being 300m short of kt offers twice as much space.
