Lateral Torsional Buckling
I am doing a buckling analysis with a plate model. The problem I have is that in the modes that I get as buckling shapes I cannot find the ones corresponding with the Eigen values vibration modes. Most of the shapes that I get are local modes of failure.
I have defined the load as masses and I have have defined the buckling analysis input following the steps in the tutorial but I am not sure if I am doing something wrong.
I am defining a dummy member in the web of the beam to apply the parapet beam load with an eccentricity, I think this can create a problem maybe in the model. How could I represent this situation in the model?
