tubular tower with thin wall
tubular tower with thin wall
(OP)
I'am trying to model a long cylinder (a tubular tower with thin wall -- d/t>120) subject to a uniform distributed load in all the length. Given the importance of the imperfections in the analysis, its possible to take them in account?
Those values aren't purely empirical?

For example - are loads truly uniform? Is the material uniform? Are the boundary conditions important?
Until you hav shown that you understand these things I'd say your model is a pretty picture.

The European codes don’t contain any relevant information for this specific case and lots of investigation has been made about it. Look the article:

Some more studies in real towers will be sent to me to compare with numerical models. There is lots of work undone.

There have been several attempts to examine imperfection geometry effects on critical buckling loads. Look at the references at my web site http://www.volcano.net/~d.citerley. You will find computer programs that will help you in the evaluation and papers on the subject (WRC Bull 313). If you need any of the references, I can forward you a PDF file of a given paper.

Iam interested in the reading of WRC Bulletin 313.
