You have two options in RFEM. On the one hand, you can determine the punching load from a single load (from column/loading/nodal support) and the smoothed or unsmoothed shear force distribution along the control perimeter. On the other hand, you can specify them as user-defined.
Calculate the design ratio of the punching shear resistance without punching reinforcement as a design criterion and the program will deliver you the corresponding result. In the case of exceeding the punching shear resistance without punching reinforcement, the program determines the required punching reinforcement as well as the required longitudinal reinforcement for you.
The punching load can be determined from a single load (from column/loading/nodal support) and the smoothed or unsmoothed shear force distribution along the control perimeter, or it can be defined by the user.
Since the module is fully integrated in RFEM, all nodes of punching shear on the reference surface are known. Therefore, you can check for collision of the determined perimeters with those of the neighboring columns.

All data are documented in a clearly arranged printout report, including graphics. In case of any modification, the printout report is updated automatically. COMPOSITE-BEAM is a stand-alone program and does not require the RSTAB license.
After the design, the punching checks are presented clearly and with all result details, so that traceability is guaranteed at all times. 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, a clarifying note is displayed.
The next result window lists the required longitudinal or punching reinforcement of each analyzed node. An explanatory graphic is also available. The 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 coherent documentation.
