Where can the deformation coefficient k def (EN 1995-1-1) or the creep coefficient φ (SIA 265) for the long-term deformations in automatic load combinator be changed.


Since the fractions of creep are taken into account for the detection in the limit state of serviceability directly on the side of the load combinator, the utilization class and thus the deformation coefficient must also be defined in RFEM or RSTAB independently of the design module. This already takes place in the basic information (see Figure 1), but can also be called directly from the combination rules (see Figure 2).
