What a nasty bug (or design flaw) in vBulletin. I just clicked the "go to first new post" icon (the chevron) and it took me to page 889 with only two posts on it. I clicked page 888 and found five more new posts that I would have missed had I trusted the "go to first new post" link. Later, all seven new posts (and a few older ones) magically became part of page 889. And now this post, and Zen's before it, are the only ones that show up on 889.

^The assertion that no modern buildings use perimeter columns is patently wrong.

+ That would be like the core takes whole building on her self..Yes, the core is the stronest part of the building but it has some limits too..You have to bolt those beams commin' out of the core to something to take the weight of everything on that floor...It's seriously impossible even to imagine something like he said...

Yeah, that's badass..I reply to the post and then I see a couple of forumers already answered to it...It starting to be annoying..

I don't think that was what Zensteeldude was saying. He was merely pointing out that the majority of high-rises today feature curtain walls, which don't act as primary structure, and therefore are not limited by the perimeter column placement. While this is nothing new, it does affect how much daylight can get in (particularly the spacing and thickness of exterior columns). In the WTC, the exterior columns were the wall, and as a result, there density and thickness only allowed for narrow slot windows, in contrast to the vast majority of buildings built today. It may still be true that other high-rises built today function the same structurally as the old WTCs did, but I seriously doubt most feature such closely spaced perimeter columns.

I'm sure that the perimeter columns of the 1WTC will play a greater role than in more conventional buildings as there is clearly quite a wide gap between them and the core columns. Modern office buildings are designed to have large column-free areas of floor space to maximise their freedom of layout.

In the case of the original WTC, both the internal core and the perimeter columns supported the vertical load of the tower (due to self-weight, furniture, people etc) whilst the perimeter columns would have taken wind loads by resisting tension on the windward face of the tower and compression on the leeward as the tower tried to bend away from the wind. The central core and the floors would act to preserve the shape of the building and so prevent the perimeter columns from buckling away from the loads applied to them. The central core would also fix one floor laterally with respect to the floors above and beneath it and so prevent the structure from swaying.

I don't know but I would guess that the triangular elevations of the 1WTC facade might also function to resist wind load.

It would be interesting to know

Sorry for asking a probably stupid question but which company is doing the facade (production + installation)? AFAIK Viracon is supplying the glass but I couldn’t find out who does the facade itself. Any ideas guys?

Oriel Chambers is in Liverpool not NYC and, even by our lower standards it is not considered a skyscraper. However along with another building by the same architect 16 Cook Street, it pioneered a structural system that is widely thought to have influenced the early Chicago skyscrapers and, hence the skyscrapers of NYC.

I mentioned this because of the discussion about the use of glass cladding in modern skyscrapers such as 1WTC, so I don't think it is that far off topic.

When I was referring to the earliest skyscrapers what I had in mind was the 10 story Home Insurance Building in Chicago (1885) or the 10 story Wainwright Building (1891) in St. Louis, which may be considered true skyscrapers because they had elevators to transport people to the higher floors.
We have lost a number of fine buildings in Liverpool but I think that Oriel Chambers is safe and that its importance in the development of building technology is now recognised. In fact, it has recently been refurbished and is considered quite a prestige address.

Yes, except for one building over 100m (that I know of) in the world that has no load on the outside of the building:
