Why Dlubal Software?
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.
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
There is a known complexity of calculating footfall response on irregular floors or staircases of any type.
- Overall maximum response factors and critical nodes
- Resonant analysis (maximum response factor, RMS acceleration, critical node, critical frequency)
- Impulsive (transient) analysis (maximum response factor, peak acceleration/velocity, RMS acceleration/velocity, critical node, critical frequency)
- Vibration dose values for both resonant andimpulsive analyses
- Response factor vs walking frequency
- Mass participation vs eigenmodes
- Velocity time history
The reinforcement proposal from RF-/CONCRETE Members can be exported to Revit. The rectangular and circular cross-sections are currently supported.
The reinforcement bars can be modified retroactively in Revit.
Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported to Revit as reinforcement objects via the direct interface. For this, you can optionally select surface, rectangular, polygon, and circular reinforcement areas in RF-CONCRETE Surfaces. In addition to bar reinforcement, it is also possible to export mesh reinforcement.
The material library already includes the Canadian types of concrete and reinforcing steel available for design. However, you can always define other materials for the design according to CSA A23.3.
The units used for the reinforced concrete design according to CSA A23.3 are adjusted to the metric system by default.

After opening the module, the materials and surface thicknesses defined in RFEM are preset. The nodes to be designed are recognized automatically. However, you can modify them manually.
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.
Parameters of the longitudinal reinforcement cover the number and direction of layers as well as the concrete cover separately defined by surface for the top and the bottom side of a slab. 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. Furthermore, you can open the design program by HALFEN, the German producer of rails for shear reinforcement. All RFEM data can be imported to this program for further easy and effective processing.
RF-PUNCH Pro determines the punching load on the basis of a single load (from column / loading / nodal support) and of the smoothed and unsmoothed shear force distribution along the control perimeter. However, it is also possible to enter user‑defined specifications.
Since the module is fully integrated in RFEM, all nodes of punching shear on the reference surface are known. Therefore, you can perform the interference check of determined perimeters with the perimeters of adjacent columns.
