Does anyone knows how to do pushdown analysis using SAP2000?

My analysis is to investigate the progressive collapse in a steel moment frame using sap2000
The procedure is to remove for example the corner column and apply the load combination that is provided by the GSA2003 guidelines with amplification factor 2(D.L+0.25L.L) and i have to get as a result the pushdown curve with load factor against displacement.
I have to increase the load gradually and push with load control the joint of the column that i had remove!
The analysis is nonlinear static analysis,and i had problem when i defined the analysis. I can't get the results
