Design Concept for Leaning Towers in China
Design Concept for Leaning Towers in China
(OP)
China is constructing the tilt towers. The towers lean 60° in two directions.
Can someone explain me what basic structural design concepts used to tilt the building at 60 degrees?
I would appreciate your response at your earliest convenience.
Thanks.

Construction continues at "full tilt" on Beijing's new 755-ft-tall China Central Television headquarters, as contractors push for completion in time for the 2008 Olympic Games. The building, designed by The Netherlands' Office for Metropolitan Architecture, Rotterdam, features towers that lean 60° in two directions. "We've got a building that permanently wants to fall over," says Rory McGowan, project director for London-based Arup Group, which is handling the structural and equipment design on the $600-million project (ENR 05/19/03 p. 32).

RE: Design Concept for Leaning Towers in China
Essentially you could consider the analogy of a cantilever projecting from a wall when you look at these buildings. The foundations would be a very key part of the job, but the engineering for such a building would not be overly challenging, however the construction would be prohibitively expensive unless you had very reliable bedrock which you were able to anchor into. Bear in mind that anchoring into bedrock does not mean developing tension in the rock, but rather grouting solid into a drilled hole with a high-tension steel cable or rod which would thereafter develop a failure cone of sufficient mass to retain the building's overturning moment.
Neat design: Thanks for the post!

Joking aside, the sloped walls might be less efficient for floor spaces...

Looking at the pictures the lean appears to be less than 30°.

This will be a very expensive building.
