RC Slab design - Error message following reinforcement calculations

[Richard_Kiernan]

Hello,

I wonder if anyone can help me.

I am getting an error message following reinforcement calculations for a flat slab design stating:

"Required types are not ascribed to SLS combinations. Calculations may be incorrect"

When i run the verification the error message then states the same.

I'm not sure how to rectify this problem. I'm fairly familiar with the ins and outs of Robot but cannot find a solution.

Under Job preferences I have selected BS8110 for code combinations.

As regards the combinations I have set them up manually.

I created case 3 ULS:  1.4Gk + 1.6Qk and case 4 SLS: 1.0Gk + 1.0Qk

I've attached a screen shot of the calsculation set up with the error message.

Thanks

Richard

Is combination 4 defined as SLS combination ?

Is your code really BS8110 , not in job pref but in Plate and Shell Reinforcement Type label assigned to panel?

Usually this warning is diplayed while SLS:QPR (quasi permanent) combination is not used for SLS check in EN based codes.

Apparently not!

I can't see how to change the code for the existing plate/shell reinforcement code parameters however, if i create a new one then it gives me the BS8110 heading. It must be because I changes the job preferences after I had created the model and assigned the plate/shell reinforcement parameter.

Thanks for your help.
