I get in the module RF-CONCRETE Surfaces at the steel stress detection in Limit state of serviceability (GZG) an unacceptability and no values for the steel stresses are issued. In addition, message 239) is output. Why is that?

Answer

According to the specifications of EC2, the steel tension design in the SLS is performed only with the characteristic combination. If no combination of the "characteristic" type is selected, the design is not carried out. There are three ways to counter this:

1. Adding an additional combination of the "characteristic" type to the selection of the combinations to be designed.

2. Changing the combination type of an already selected combination so that it is regarded as a characteristic combination.

3. Modify specification of standard and activate design in detail settings for other combination types (frequent or quasi-permanent).
