How to input the partial factors for ULS and SLS

Load cases as self–weight or ceiling are added in the characteristic values. If we input the load cases from the joints, we apply the partial factor of 1 due to the design value extracted from the IDEA StatiCa Connection. Nevertheless in SLS, the situation is not so simple due to the fact that design values cannot be separated from the point of view of permanent and variable loads and divided by appropriate partial factors. The reason is the non-linear analysis in IDEA StatiCa Connection, so we cannot use the superposition of the loads. Regarding this effect, we have chosen a partial factor of 0.75, which comes out from the equation 1/1.35.
