Generation of Case Components and their use in Load Combinations

[sshasni]

Dear Arthur Kosakowski and Rafal Gaweda,

First of all my heartiest gratitude for you, for providing your proficient expertise in time, unconditionally to the expeditors of RSA. Your kind solutions are helping me a lot in transitioning to the state of the art RSA.

In my structure am having three Bays having  of cranes simulated as SMS BAY CRANE, WORKSHOP BAY CRANE and ROLLING BAY CRANE in my structure, and in order to simulate the critical load cases for the columns along grid B and grid C,  I wish to sort out the critical load cases, combine them and then use them in my load combinations. I have tried to use manual load combinations generation module available in automatic load combinations module. After alloting the groups to the case components and defining the relations as shown in the attached snaps, I see no combination generated. Please confirm if there is an error in the steps i am taking or fully manual combinations is the only solution.

Also, when I generate critical case components from the defined manual combination of SMS BAY CRANE + WORSHOP BAY CRANE, it does appear in the list of loads but after running the analysis, these are no longer available.

I would request your advice for this issue.

Following is the link to the model

Thank you very much.

I made such tests:
1. all dead + wind + Q1 AND Q3 :
number of ULS combinations: 6736
number of SLS combinations: 2016

2. all dead + wind + Q1 AND Q3 AND Q4:
number of ULS combinations: 169600
number of SLS combinations: 52560

3. all dead + wind + Q1 AND Q3 AND Q4 AND Q5:
number of combinations : millions , unknown time of generation or I was impatient
