Markus Baumgärtel Design RFEM RSTAB

If I look at the results of the GZG deformation checks in the RSTAB working window add-on modules, much more value is given for both local and global Z-direction deformation than in the additional modules.

Answer

In the control of the deformation value, the z. If, for example, STAHL EC3 outputs the deformation analysis, the nodal deformations must be subtracted from the overall deformation shown in RSTAB (see Fig. 01): The deformation value in the center of the bar represents the total deformation of the component (deformation of the nodes plus deformation of the component).

If the deformation is referenced to the "undeformed system" in the detail settings of the additional module for the usability proof (see Figure 02), then the maximum deformation including the nodal deformations (deformation value displayed in RSTAB / RFEM) is used.
