STAAD.Pro | Command to Reduce Element Stiffness For Secondary Order Analysis

Hi, I need to perform a secondary order analysis in STAAD.Pro.

Question: Is there a command in STAAD.Pro to reduce the stiffness of the element by multiplying a factor to the gross element stiffness when modeling for the 2nd order analysis?

I look forward to your reply.

Please advise.

Thanks,

Denisson
