Question

The calculation in STEEL EC3 according to General Method or after the warping torsion analysis is unsuccessful. Unfortunately, I cannot graphically control the mode shape. Why?


Answer:

To display the mode shape, the calculation must be successfully performed. If this is not possible, there are either invalid boundary conditions or no stability problem was found (convergence not reached). No critical buckling shape can be considered then.
