RFEM supports you and save you a lot of work. The materials and surface thicknesses defined in RFEM are already preset in the Concrete Design add-on. Thus, you can directly define the nodes to be designed.
Any openings in the area with risk of punching shear are automatically taken into account in the RFEM model. The add-on recognizes the position of the nodes of punching shear and automatically determines whether it is a node of punching shear in the center of the slab, on the edge of the slab, or in a slab corner. Again, you save your time.
You can individually select the method for determining the load increment factor β.
Is the design completed? Then sit back. Because the punching checks are presented for you clearly and with all result details. This allows you to precisely follow each result. The program shows you the provided and allowable shear stresses for the shear resistance of the slab in detail.
RFEM has even more to offer in this add-on. In the next result window, it lists the required longitudinal or punching reinforcement of each analyzed node. You can also find an explanatory graphic there. RFEM shows you the design results clearly displayed with values in the work window. You can integrate all result tables and graphics into the global printout report of RFEM. Thus, you can be sure of a clear documentation.

Are you afraid that your project will end in the digital tower of Babel? The Building Model add-on for RFEM supports you in your work on a construction project with several stories. It allows you to define a building by means of stories at specified elevations. You can adjust the stories in many ways afterwards and also select the story slab stiffness. Information about the stories and the entire model (center of gravity, center of rigidity) is displayed for you in tables and graphics.
After opening the module, the materials and surface thicknesses defined in RFEM are preset. The nodes to be designed are automatically recognized but can also be modified by the user.
It is possible to consider openings in the area with risk of punching shear. The openings can be transferred from RFEM or specified only in RF‑PUNCH Pro so they do not effect the stiffnesses of the RFEM model.
The parameters of the longitudinal reinforcement are the number and direction of the layers and the concrete cover, specified separately for the top and bottom of the slab on a surface-by-surface basis. The next input window allows you to define all additional details for nodes of punching shear. The module recognizes the position of the punching node and automatically sets, whether the node is located in the center of the slab, on the slab edge or in the slab corner.
In addition, it is possible to set punching load, load increment factor β, and the existing longitudinal reinforcement. Optionally, the minimum moments can be activated for determining the required longitudinal reinforcement and enlarged column head.
To facilitate orientation, a slab is always displayed with the corresponding node of punching shear. You can also open the design program by HALFEN, a German producer of shear rails. All RFEM data can be imported to this program for further easy and effective processing.
