buckling analysis

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
