1. interpretation of buckling/necking

Hello at all, i made an analysis of a wireframe of a formula student car and created some loadcases for buckling. In HyperView there are some negative and some positive magnitudes for F (for buckling mode 4). I´m quite sure that this is the factor λ. So i thought if λ>0 (positiv) there is no buckling and if λ<0 (negativ) then there is buckling. Now i noticed, in every case where are the negative magnitudes, then a tension rod is buckling or deforming and when there is a positive magnitude then a pressure bar is buckling. I thought only rods/bars under pressure can buckle. My problem is to interpret these cases. Could it be that the buckling of a tension rod is a kind of neckling??? And when it is a kind of neckling, how to give an interpretation of the buckling? Why are tension rods are deforming in my buckling analysis? I hope you can help me. Regards, Rizzo
