Question:
How can I set the deformation coefficient k-def in the program?
Answer:
You can set the deformation coefficient k-def under the General Data of the model. There, you can specify the deformation coefficient manually or select it on the basis of the service class.
The program considers the deformation coefficient k-def in the load combinations for serviceability (similar to DIN EN 1995‑1‑1, 2.2.3).
