Question:
How are the creep and shrinkage for columns considered in RF‑CONCRETE Members?
Answer:
In terms of the consideration of creep and shrinkage, the program concept is as follows: Creep and shrinkage are only considered in RF‑CONCRETE Members if there is a curvature and if the cross-section is cracked. The explanation for this can be found in the manual; see Chapter 2.4.5.2.
The concept for determining the longitudinal stiffness is designed for curved components. In the case of pure axial loading, the program is unable to determine the exact deformation in connection with the creep and shrinkage according to the current concept.
