Dear Friends, after performing spectral EQ analysis and combine gravity with EQ as per below post file the Posview is showing deferent UCs and it's not considering the 1.7 modifier.

Need your urgent feedback please.
Hello Ahmad
You are checking the load condition 3 and this load isn't included in the cad AMOD, you need to add load 3 to the AMOD card only in this way this will have factor 1.7
If the load condition is the result of the combination of load 1 and 2, the factor of 1.7 will be applied only in load case 3
Hello Ahmed,
If you see the post input, I am only selecting load case 1 and 2 and they are independent load cases from gravity and seismic there are no selection for other load cases.
Any Idea?
Cheers,
Ahmad
I understand what you want to do and I think that is related to this wiki Please review the Geoff's answer

only to get more knowledge about your model, what you are trying to do is combine two CSF (common solution file), one with the result of spectral EQ and the other one with gravitational forces? Have I understood well?
Hello Ricardo,
Yes, its CSF for seismic combined with gravity. below is the dynpac input.

Hello Ahmad Sanad
After running the Spectral earthquake combination analysis, you need to run a post-processing analysis,
And in this step, you need to create a preprocessing file in which you request the creation of a postvue, This is where you can add the AMOD for elements
This will require that you provide the next files
- Model
- Common solution file
- Post-processing file
