Three layered reinforcement problem


Could anyone suggest a solutions for the following problem. I am designing a slab where I need to use three layered reinforcement. I was successfully able to run the “Design ULS (Area elements)” and “Design SLS (Area elements)” tasks. I also checked the presence of reinforcement in Interactive Graphics. However, when I try to run the “Non-linear Analysis SLS (Area elements)” I get the following error:

Any suggestions are appreciated

With best regards,


I now understood that it means SLS checks for three layered reinforcement is not implemented in the program. The workaround was to model the reinforcement as multi layered
