I am doing a buckling analysis in STAAD.Pro and getting the following message
"Warning THE LOADS IN CASE xx ARE IN THE OPPOSITE DIRECTION TO THE LOADS THAT WILL CAUSE BUCKLING". What does the message mean ?

This message is generated by the basic solver during a buckling analysis.  It means that no positive factor times the load will cause global Euler buckling or in other words the direction of the load is opposite to what would cause buckling in the structure. Please try reversing the load (add a load case with a repeat load factor of -1.0) and you should be able to get buckling factor for the REPEAT LOAD.

For a similar buckling mode, the advanced solver would report a negative buckling factor.
