The punching load can be determined from a single load (from column/loading/nodal support) and the smoothed or unsmoothed shear force distribution along the control perimeter, or it can be defined by the user.
Since the module is fully integrated in RFEM, all nodes of punching shear on the reference surface are known. Therefore, you can check for collision of the determined perimeters with those of the neighboring columns.
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.

After the design, the punching checks are presented clearly and with all result details, so that traceability is guaranteed at all times. The provided and allowable shear stresses for the shear resistance design of a slab as well as various perimeters and reinforcement ratios are represented in detail. If necessary, a clarifying note is displayed.
The next result window lists the required longitudinal or punching reinforcement of each analyzed node. An explanatory graphic is also available. The design results can be clearly displayed with values in the work window. Furthermore, you can add all result tables and graphics into the global printout report of RFEM, which guarantees coherent documentation.
Main Program
The new generation of 3D FEA software is used for the structural analysis of members, surfaces, and solids.
Add-On
The Concrete Design add-on allows for various design checks according to international standards. You can design members, surfaces, and columns, as well as perform punching and deformation analyses.
Add-On
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Add-On
In RFEM, the Geotechnical Analysis add-on uses properties from soil samples to determine the soil body to be analyzed. The accurate determination of soil conditions significantly affects the quality of the structural analysis of buildings.
Add-On
The Modal Analysis add-on allows for the calculation of eigenvalues, natural frequencies, and natural periods for member, surface, and solid models.
Add-On
The Response Spectrum Analysis add-on performs seismic analysis using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from them. The add-on includes an extensive library of accelerograms from seismic zones that can be used to generate the response spectra.
Add-On
Using the Pushover Analysis add-on, you can analyze the seismic actions on a particular building, and thus assess whether the building can withstand an earthquake.
Add-On
The Building Model add-on for RFEM allows you to define and manipulate a building using stories. The stories can be adjusted in many ways afterwards. The information about stories and the entire model (center of gravity) is displayed in tables and graphics.
Add-On
The Masonry Design add-on for RFEM allows you to design masonry using the finite element method. It was developed as part of the research project titled DDMaS – Digitizing the Design of Masonry Structures. The material model represents the nonlinear behavior of the brick-mortar combination in the form of macro-modeling.
