AnswerThe proof of steel stress in the GZG is only guided with the characteristic combination according to the specifications of the EC2. If no combination of the type "characteristic" is selected, the verification is not carried out. There are three ways to counter this:1. Add an additional combination of type "characteristic" to select the combinations to be designed.Second Change the combination type of an already selected combination so that it is considered a characteristic combination.Third Modify default of the standard and activate the proof in the detail settings also for other combination types (frequently or quasi-constantly).

Generally, the module assumes that there is a rigid coupling between the layers.
More information about the calculation with the RF‑LAMINATE add-on module can be found in the respective manual. This also explains special features of various material models (isotropic, orthotropic, and hybrid).
At this point, it is recommended to create load combinations:
First, create a new "Prestress" load case, see Figure 1.
Only within this load case should the corresponding prestress be entered as a member load. The action category "prestress" is considered as permanently acting just like the self-weight. Thus, the load case prestress is included in all generated load combinations when activating the automatic load combinatorics, see Figure 2.
AnswerFor this, you have to model the entire structure (panes, spaces between panes, and supports) directly in RFEM.The design of the panes can then be carried out by means of the "global calculation type" in RF‑GLASS.The only difficulty here is that the loading from climatic loads cannot be applied automatically, but must be defined manually.As an aid to modeling, you can use a temporary model.
AnswerGenerally, the unit of the spring stiffness is given in kN/m. Also, the line supports always refer to one meter of length.This results in the unit kN/(m*m) and summarized kN/m².
AnswerThe property of the material masonry depends on a large number of input parameters. It would be very extensive to list all possible combinations. To create a material, click the "Create new masonry material ..." button. Once created, the material remains in the library for repeated use.
AnswerIt is currently not possible to display a concrete-concrete composite cross-section. For this, the structural state calculation must be coupled with the concrete cross-section solver. We are currently working on the possibility that this will be possible in future versions.
It appears that the versions RFEM 5.18.01 and Halfen HDB 13.21 are not compatible.In RF-PUNCH Pro, I receive the error message saying that the design program Halfen HDB can not be found. This is installed and registered with me.What can I do?
AnswerIn fact, there is a shortcoming in the interface between Halfen HDB (version 13.21) and RF-PUNCH Pro (5.18.01). We have fixed this deficiency by updating it.You can find the download link for the update via the download area of your Dlubal Account or directly by the message of our hotline support.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
