Ðroportioning of a steel column cross-section

When setting some construction materials, it displays a message about the incompatibility of stiffness (I used a round tube) withconstruction materials. As a result it is impossible to proportion asection. How to proportion a round pipe cross-section for a column in LIRA?

Hello, SZett!
Which version of the program do you work with? Attach the task file for clarity.

Sincerely, Alexey Tishchenko

SZett, you have to create a material compatible with the rolled pipes.
For this you need:
1) Set the pipe stiffness ("Pipe 325 x 6") as a a current or mark the elements with the given rigidity in the scheme, see the picture;
2) "Add" a new material;
3) Sel ect the required one fr om the list of steels;
4) Destine the created material to the elements of the columns.

Sincerely, Alexey Tishchenko
