  • Answer

    You can save the manually or automatically created and adjusted combination schemes and use them in another RFEM/RSTAB file. The video shows that on a simple example.
  • Answer

    Yes, this is possible by using a combination scheme. It allows you to create user-defined templates.

    You can open the Combination Scheme using the "Tools" menu. A scheme defined there can be used as a template for your loading data. You can create a combination scheme in any model and access it from any model.

    In a combination scheme, define the load cases, load and result combinations with the relevant design parameters and basic settings. In addition to the number of LCs, COs and RCs, you can also define the factors and the type of the superposition in a combination scheme.

    When creating a new model, you can then quickly access these settings, so you only have to enter the contents of the load cases (member loads, and so on). If you have already created several schemes, you can select one of them from the pull-down list.

    Click the [New Scheme] button to create another combination scheme. In this way, you can copy the existing load cases and combinations of the present model.

    The [Generate in Tables Defined Load Cases, Load Combinations, and Result Combinations] button transfers the current combination scheme to the model.

    The combination schemes can also be exported to Excel and then imported again.

    The user-defined combination schemes are stored in the KombinSchema.dat file, which is located in the master data folder "C:\ProgramData\Dlubal\Global\General Data" by default. If you copy this file to another computer, you can also use the combination schemes there.
  • Answer

    In the case of Schöck Isokorb®, tensile forces are absorbed by stainless steel and compressive forces by micro‑fiber reinforced high-performance concrete with PE‑HD plastic coating through the insulating layer. Depending on the selected type, moments and/or shear forces can be transferred. This limited force transmission must be considered in the structural analysis.

    Technical information according to EC 2 [1] for Isokorb® includes a FEM guideline where the modeling is described.

    Basically, the modeling in RFEM can be done using line hinges or line releases between the respective surface elements. There is the following distinction:

    • Line Hinge
      The line hinge should rest on the external side (balcony side). However, it is not possible to consider any nonlinearities when using the line hinge.

    • Line Release
      It is possible to enter nonlinearities. This allows you to consider the spring ineffectiveness of Isokorb®.

    The detailed procedure for entering Schöck Isokorb® together with model files is described in the technical article in our Knowledge Base, which you can find under Links below. Furthermore, there is a webinar dealing with the modelling of a balcony slab using Isokorb®.

  • Answer

    You can select the two masks 'Steel Schedule' and 'Concrete Cubage' in the printout report.

    To do this, switch to the global selection in the printout report (menu item 'Edit'), select the FUND Pro program, and then the 'Results 1' tab. Select the 'Reinforcement Drawings' check box and click 'Details' next to it.

    In the 'Reinforcement Drawings to Display' window that appears, select the 'Parts List'.

    After confirming with [OK], the parts list and the concrete cubage are displayed together in one graphic.

  • Answer

    Yes, aligning new structural elements to existing ones is very easy and is already possible when defining them.

    Go to the "Tools" menu and select "Coordinate System". A dialog box opens where you find the button "Create New User-Defined Coordinate System".

    You can use this button to create a user-defined system of coordinates with which the work planes are aligned. If you choose the points defining the coordinate system in such a way that they are corner points of the existing surface, one plane of the new system of coordinates is already determined by that surface plane, and the other two work planes will be perpendicular to it.

First Steps

First steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

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.

Your support is by far the best

“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. ”
