Distribution of Principal Internal Force v_max, b in Floor Slab
In RF-PUNCH Pro, you can perform the punching shear design on wall corners and wall ends. The basis for the design is the punching load, which is automatically determined from the RFEM internal forces in the connected surface. Since the surface internal forces from the RFEM calculation may be subject to the influence of singularity locations, this can also have a negative influence on the determined punching load at the wall corner or end. This article describes possible optimization options that you can use to minimize this unfavorable influence.
Punching Shear Design Without Enlarged Column Head
In RF-PUNCH Pro, enlarged column heads can be arranged at point-supported punching shear points, thus increasing the shear force resistance of a reinforced concrete floor. In the following article, we will show the punching shear design with the optional application of an enlarged column head.
Input Table 1.5 Nodes of Punching Shear
RF-PUNCH Pro performs punching shear design on concentrated load application locations (column connection, nodal support, and nodal load) as well as on wall ends and wall corners.
Example of Model
With RF-PUNCH Pro, the punching shear design can be performed according to 6.4, EN 1992‑1‑1. In the following example, the design according to DIN EN 1992‑1‑1 will be presented first with automatic design of the inner and outer perimeters and then on the basis of the inner perimeters defined by the user on a simple example.

Product Features
Material model Anisotropic | Damage, nonlinear behavior, concrete and reinforced concrete

The "Nonlinear Material Behavior" add-on includes the Anistropic | Damage material model for concrete structural components. This material model allows you to consider concrete damage for members, surfaces, and solids.

You can define an individual stress-strain diagram via a table, use the parametric input to generate the stress-strain diagram, or use the predefined parameters from the standards. Furthermore, it is possible to consider the tension stiffening effect.

For the reinforcement, both nonlinear material models "Isotropic | Plastic (Members)" and "Isotropic | Nonlinear Elastic (Members)" are available.

It is possible to consider the long-term effects due to creep and shrinkage using the "Static Analysis | Creep & Shrinkage (Linear)" analysis type that has been recently released. Creep is taken into account by stretching the stress-strain diagram of the concrete using the factor (1+phi), and shrinkage is taken into account as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.

Feature 002918 | Determination of Required Longitudinal Reinforcement for Direct Crack Analysis

In the Concrete Design add-on, you can determine the required longitudinal reinforcement for the direct crack width analysis (w k).

Feature 002920 | Automatic Function of Longitudinal Reinforcement for Members

For the design of reinforced concrete members, there is the option to automatically determine the number or diameter of rebars.

Feature 002876 | Reinforcement Results in Tables by Design Situation

For concrete design, you can display the reinforcement results in tables separately by design situation.

Frequently Asked Questions (FAQ)
I installed Halfen HDB 13.60 on my PC. The version does not seem to be compatible with RF‑PUNCH Pro anymore. The interface does not work. I am using version 5.26.02 of RFEM.
What defines the dimensions "Length of Reinforcement" and "Width of Reinforcement" of the longitudinal reinforcement in RF‑PUNCH Pro? Is the anchorage length included?
Where in RF‑PUNCH Pro is the direction of the individual reinforcement layers displayed?
When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
How can I graphically display the determined load increasing factors ß from the RF‑PUNCH Pro calculation?
I would like to perform punching shear design on a column with downstand beams as a wall corner or wall end. However, the module applies an internal column. Is it possible to adjust it?
