Markus Baumgärtel Design RFEM RSTAB

It concerns the deformation proofs in the GZG with the additional modules. Looking at the results in the viewport of RSTAB or RFEM, a much larger value is output for both local and global Z-direction deformation than in the additional deformation modules.


In the issued deformation value, the z. If, for example, STAHL EC3 is used in the proof of deformation, the nodal deformations must be subtracted from the overall deformation shown in RSTAB / RFEM (see Figure 1). This value thus corresponds to the total deformation of the individual component.

If the deformation is related to the undeformed system in the detail settings of the additional module for the usability proof, the maximum deformation including the nodal deformations (indicated deformation value RSTAB / RFEM) is used (see Figure 2).
