Punching Shear Design of Foundations and Slabs with Nodal and Line Supports

The RF-PUNCH Pro add‑on module performs the design of punching shear resistance for singularly or linearly supported surfaces. The module automatically determines the governing punching load from the specified load. Also, it is possible to apply a concentrated punching load to a slab manually.

With RF‑PUNCH Pro, you can quickly and efficiently perform punching shear design according to the following standard:

    • Optional consideration of minimum moments according to EN 1992‑1‑1 when determining longitudinal reinforcement
    • Design or analysis of longitudinal reinforcement
    • Complete integration of results in the RFEM printout report
  2. Definition of punching shear parameter

    Input

    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.

  3. Results of punching shear design

    Design

    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.

  4. Graphical result of required punching shear reinforcement

    Results

    After the calculation, the module displays clearly arranged tables including all result details to ensure traceability at any time. 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, there is a clarifying note displayed.

    The next result window lists the required longitudinal or punching shear reinforcement of each analyzed node. An explanatory graphic is also available. All 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 a coherent documentation.
