When you start RF-PUNCH, the materials and surface thicknesses defined in RFEM are already preset. If still necessary, you can select the nodes that you want to design manually or graphically.
Furthermore, it is possible to take into account openings existing around the relevant area with risk for punching shear. Those openings are either already known from the RFEM model or can be specified additionally in RF-PUNCH so that the model's stiffness won't be affected. Moreover, it is possible to define those openings subsequently in the graphic by using rectangular or circular openings.
As parameters of the longitudinal reinforcement, the number and direction of layers as well as the concrete cover are defined by surface, separately for the plate's top and bottom sides. A further input table allows you to define all additional details for the punching shear points, such as the settings for the perimeter to be considered, the available longitudinal reinforcement and the punching shear reinforcement.
To provide a clear overview, RF-PUNCH always displays the plate with the corresponding punching shear point. Furthermore, it is possible to start the design program developed by HALFEN-DEHA, a German producer of shear rails, in the final input table. In this way, all information set in RFEM can be transferred quickly and easily for further use.
