buckling of steel column
buckling of steel column
I want to model a steel structure, whose columns are capable of buckling. I know that I have to introduce an imperfection inside my element as well as refined mesh. I just want to know which of the three models which are introduced inside the software for steel is suitable for modelling the buckling.

Re: buckling of steel column
In principle, any model should be fine since the buckling will be mainly driven by geometrical nonlinearity, rather than material one.
However, if one uses an adequately calibrated 'stl_mn' model, it will obviously be easier to simulate buckling. The same happens for the 'stl_mp' model with a negative value for the 'a3' parameter, which is perhaps the model that we would reccommend.
