Load combinations for nonlinear load cases

I am analyzing a system under static loading, considering geometric nonlinearity. I’ve written the attached code. Is it okay, or is there a more efficient way to handle this?

This approach becomes tedious when dealing with multiple load cases.

This is ok.

And yes, when you have multiple loadcases/combination nonlinear analysis is going to be very laborious.
One way to deal with it is to perform linear analysis first and find the worst cases to deal with.
