Hi everyone,
I'm trying to analyze a model with a response spectrum in x & z direction, and then combine them in a Load with 100% of one direction and 30% of the other, I try with Repeat load and the software indicates the following:
**ERROR- CASE BEING FACTORED IS DYNAMIC. CASE= 11
And then I change the repeat load to a load combination and the error was solved, this means that STAAD can't solve a dynamic case with a non-linear analysis?
Can you provide me with a further explanation?
