Error in buckling analysis

Hello everybody!

 

In all versions of Robot there is the same error in buckling analysis. When we want to solve an eigenvalue problem to obtain load buckling factors the structure have to be manually divided into small elements. Otherwise we could get a huge error, although the program tells the user that an error is very small as we can see in Fig. 1 and 2.

Hi @rholubowski

 

This error almost in all other softwares also  and many codes require when you do p-delta analysis to divide the members.
