Sometimes I obtain negative critical load factors in RF-STABILITY. How do I go about this?

Question

Accepted Answer

For negative eigenvalues, no stability failure occurs due to the tensile forces in the model. It is not possible to make a statement about the expected buckling and buckling behavior. If negative critical load factors are shown, the number of stability figures to be determined should be increased. If the number is too small, it is not possible to hide the negative eigenvalues to display only the positive, realistic results. Alternatively, you can use the ICG eigenvalue solver method to exclude negative critical load factors.
