RE: Wind tower design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I doubt that you will find any sort of code or design guide on this topic.  I would suggest that a wind tunnel study be conducted especially if this is for operational wind load characteristics.  If this is for extreme wind effects, I would think that the dominate issue will be the vortex shedding on the mast.

Subject: Wind tower design

Has anybody done any wind tower design work ?  I am doing some preliminary work on a concrete tower design, and I am thinking about the dynamic behaviour
and the effect of the passage of the blade when it passes in front of the tower.  Does anyone have any information or ideas on this ?

The Germans and the Japanese have actually built some concrete towers already.  Apparently steel towers are at about their height limit now, and the way to greater efficiency and bigger turbines leads to higher towers, which will probably be in concrete.
