Thanks alot helghast for sharing that video. Very interesting!

Here is also something of interest. Renders of the Burj Dubai from the SOM website that I hope haven't been posted before. Enjoy

There are no steel bars that thick. 1.5m is the diameter of the piles themself. Considering the building's height, slandernes and weight, 50 meters isn't that special either. They might have found some bedrock down there.

Seven architectural wonders chosen

Burj dubai is the N0.1 architectural wonder
NEW YORK (AP) - From the tall tower in Dubai to the new addition at the Royal Ontario Museum in Toronto, noteworthy architecture is springing up around the globe. Conde Nast Traveler's April issue picks seven designs as the "new seven wonders of the architecture world." They are:


* Burj Dubai, the world's tallest building, which is under construction in the Middle East and is already more than 1,700 feet (518 metres) tall. The final height is a secret but its developer, Emaar Properties, has previously said it will stop somewhere above 2,275 feet (693 metres) and will exceed 160 floors.

I agree. There's nothing particularly impressive about the individual piles for this job....just a lot of them! Does anyone know if the footing system is designed for net tension or whether minimum dead loads offset uplift due to lateral wind loads?

I maybe wrong but I would suggest they are there for structural reasons - to prevent vortex shedding and limit resonance under wind loading. This in turn reduces lateral movements and limits fatigue damage to the steel.

We put similar things on a really tall chimney on an industrial job I worked on. This was on an ugly industrial site, so definitely not for appearance in that case!

But maybe I'm overanalysing this case and it's just for looks. But the height of the spire is significant, even though it looks small compared with the rest of the building. I assume the structural engineers would have done some serious vibration analysis for the spire, especially in relation to wind vortex behaviour.

You're correct. It was discussed many pages (or threads!) ago. They were added to the pinnacle design to reduce wind resistance.

Apparently there'll be 40 extra stories of BURJ DUBAI left. ???

According to www.burjdubaiskyscraper.com.

This means more floors than all the steel floors left of the tower. Maybe its wrong.

I purposely avoided the Burj Dubai thread for about two months so I could be amazed with the progress...

seeing the pics above I have only two words -

holy shit.

Merged photo

I've been following this thread (among few others) for over a year and have learnt a lot! At the moment I can't have any special contirubution, but hopefully in the future that will change. In the meantime I'll probably do some minor photo adjustments etc. Keep up the good work!

Skymyhusband posted some images taken by Kirre, here is a merged one which shows quite nicely the whole structure with some mech cladding on.



Full size (1,000x3,200 pixels)

The 516 meters tall Pentominium in Dubai Marina, designed by AEDAS has more then 200 piles going deeper then 60 meters and they are designed to counter the uplift due to lateral wind loads.

I am not a professional but based on what we have heard during the years, I believe in the case of BD the tower's design itself, combined with the sheer weight of the raft foundation, would take care of that.
