I've noticed you in plenty of US threads, trying to make fun of something (like in Wilshire Grand Center a couple of months ago, if I remember correctly you were having some sort of ironic California dreaming comment). And you always seem to care more for politics (Metropolis in this case) rather than architecture. If you aren't impressed from this projects then skyscrapercity has a lot more threads from a lot more countries and cities, you should not bother checking these projects at all. That's my advice for you stick to the projects that you really like, or at least write something on topic for once. Bye bye.

I never realized how massive this building is gonna be till I saw it in person.



This is truly a massive site. Definitely reminiscent of when the WTC was under construction.

You're taking yourself a little too seriously...calm down, this is just an internet forum about tall buildings

You're right about this being an internet forum about tall buildings, certainly not the right place to discuss LA's social problems, or even worse trying to make fun of them...hmm...but what do I know I'm just taking myself a little too seriously. I'm okay with him criticizing architecture that he thinks should be better, but I've hardly seen a post of him like that, all I saw was discussing which country has a bigger economy, bigger buildings, bigger staff, it's okay we saw it, he can put his pants on.

So there is no concrete core for this building? That's pretty amazing to me, 30 HY must be the tallest building going up without one.

Not that amazing. That thing of concrete cores is something relatively new. Sears Tower doesn't have one, the Twin Towers didn't had one either, and the ESB certainly doesn't have one.

A concrete core has become the standard for skyscrapers, because it is efficient and simple, but it is not like it's mandatory. In the case of this building, erected above an active railyard, it wasn't possible to build a concrete core, it would've landed directly on the tracks. They have to use a complex system of leaning columns, trusses and diagonal bracing instead, in order to avoid the tracks.

I seem to recall that the Twin Towers did have cores, and that they were some of the first to do so.

They indeed had cores but they were not concrete. The cores at the twins were framed in structural steel.

I raised similar questions and got great responses, this one from NYStruct (post 4764):

"It's not only the twin towers or the ESB, there are many buildings in NYC which are made of structural steel framing relying on a "steel core" composed of braced frames. I made a post listing some of them previously.

There is no building code requirements to design a building to withstand the impact of a plane. Considering the low probability of occurrence, that would be insanely detrimental from the economic standpoint and the money is better spent ensuring better security in airports and planes.

Regarding bomb threats, there are blast protection design requirements and analysis for the structural members and connections. The members in the core and brace frames are "oversized" in the sense that it would take a lot of heat and time before the capacity would be significantly reduced + they are also "protected" with fireproofing or intumescent painting and there will also likely be a sprinkler system.

Lastly there are several cores with braced frames for this particular building (as opposed as just one main core in concrete buildings) to provide redundancy - so if one core/stairwell is disabled, another one would be available."

The tower portion is now gaining height. Such a long way too go still. This is going to be a skyline changer for NY. The start for a massive addition to the midtown density.

Great to see these kind of developments are still possible in NY.
