I have designed a reinforced concrete column as a solid and would like to perform a punching shear design for the connection of the column to the ceiling. Is it possible with RF-PUNCH Pro?


For the punching shear design on a column, RF-PUNCH Pro requires a node at which the axial force of the column can be tapped for the design.

If you have displayed the column as a solid (for example, with a rectangular cross-section) and directly connect this solid to the floor, you cannot use this situation for the design in RF-PUNCH Pro. The member internal force is missing because only one solid is used.

However, you can provide the end of the solid with a short coupling member (for example, a rigid member). Then, the rigid member can be connected to the floor at an end node, and the axial force in the coupling member can be used for the punching shear design.

Please note that the dimensions of the coupling member or rigid member need not be defined in the RFEM model. Therefore, the RF-PUNCH Pro applies standard dimensions for the column cross-section.
