DEAR @Anonymous 

You have to select the ULS combinations (type 4to6), because Robot give you the opportunity to run the design of single load cases.

Unfortunately in ARSA 2022 there is a bug that delete the combinations label each time that you run the calculation, so you have to select them many times.

Hope I help you, cheers

Hello, My question is when i select combination 4 and close, the ULS is still empty, it cannot by select to add,and just be added by manual input. what should I do?

[StefanoPasquini6790]

Well @Anonymous ,

easy to solve, you have two way to test:

1_ digit manually the combination in the uls field (digit 4), or

2_check the nature of your combination, doing this:

1. Open the table "combinations";
2. go to the label "edit"
3. click the RMB and select column and add "Type of combination", this way you can check and change the nature of your combination, if it's not set to ULS change it.

One of this workaround it will work, if not share your model so that I can check it directly.

Cheers

Hi @Anonymous ,

I've just checked your model, it's alla ok, but I reported a Robot bug in your topic, that I noticed that happens for Manual combinations (in your case) such as automatic combination (I've done in your model).

The workaroud, waiting for an hotfix, is to type manually the combination list in the dialog field, in your case you have to digit "4to6" and Robot will run correctly the design code checks.

I don't know exaxctly which is the problem, but I told you the solution.

Cheers

Dear Dev team and @okapawal , this topic have to be investigated. I reported the same problem in wood design.
