buckling analysis

Question

Steel plate with buckling .STD 
 hello guys , here the attachment of std file i need to take buckling analysis with the model, so that I need to include the wind load and all other loads and moment (or lumped mass at the top is enough to do the buckling ) 
 ITERATION BUCKLING FACTOR UPPER BOUND LOWER BOUND 0 1.00000000E+00 0.00000000E+00 0.00000000E+00 1 2.00000000E+00 1.01000000E+10 1.00000000E+00 2 4.00000000E+00 1.01000000E+10 2.00000000E+00 3 8.00000000E+00 1.01000000E+10 4.00000000E+00 4 1.60000000E+01 1.01000000E+10 8.00000000E+00 5 3.20000000E+01 1.01000000E+10 1.60000000E+01 6 6.40000000E+01 1.01000000E+10 3.20000000E+01 7 1.28000000E+02 1.01000000E+10 6.40000000E+01 8 9.60000000E+01 1.28000000E+02 6.40000000E+01 9 8.00000000E+01 9.60000000E+01 6.40000000E+01 10 8.80000000E+01 9.60000000E+01 8.00000000E+01 
 what can i conclude with this buckling factor , plz explain

Once you perform a buckling analysis, you will get a buckling factor for each load case. This factor is telling if the structure buckles with the applied loads in that load case or not. Buckling Factor is the amount by which the load case must be factored for the buckling shape to occur. So if the buckling factor is less than 1, this indicates that the structure will buckle for the applied loading.
