Improve buckling analysis for seel beams

[iegia]

Improve flexural, torsional, flexural-torsional, lateral-torsional buckling analysis in steel beams, adding Warping torsional degree of freedom for steel beams.

There are some software  (STABLAB, SOFISTIK) use a beam finite element directly developed for the analysis of thin-walled spatial steel members. This element is based on Vlasov theory and has 7 degree of freedom at each node (3 displacements, 3 rotations and 1 warping freedom).  You don't need to built a model based in shell elements to realize the buckling analysis of the steel profiles.

Totally agree. The software also Winsteel this type of calculation with 7 degrees of freedom. It is thus possible to know the exact length of buckling and lateral buckling elements. If this were included in the Robot, it would undoubtedly the best program for calculating the market.

This functionality is today standard. All softwares, including SCIA Engineer, RFEM (Dlubal), Sofistik, etc. have implemented analysis via 7 degrees of freedom. It is absolutely needs for assesment of lateral-torsional buckling of beams with for example U shape (Channel) sections, because for example analysis according to EN 1993-1-1 code is made only for bi-symmetric sections. Unfortunately, development of Robot always sleeping ...

Many structure calculation software already have implemented the calculation considering 7 Dof, we hope that Robot implements this function in future versions

The next year my desire will be 10 years old!

How time goes by and still no one answers...

Hi IEgia, yes 10 years! Robot seems to be doing almost no development on the computational side, the question is whether it makes sense to pay Autodesk for this software...
