As Conrad said, any commercial software can do the regular progressive collapse.  In the FEMA 439 project Degenkolb employed SAP 2000 for progressive collapse. 
LSDYNA is another program that can accommodate progressive collapse if higher degrees of sophistication are required.  There are also commercially available programs such as:

As far as I am aware there is no commercial software at present for progressive collapse, just research. Also progressive collapse is more a qualitative issue than quantitative.


Any frame analysis software with a programmable interface would be helpful for the analysis. Without the programmable interface simply copy the model, delete the members and change the loads. With a programmable interface automatically delete members and change loads using the one model, and search for the critical condition.
