Question

Can I create a punching shear reinforcement in RF‑FOUNDATION Pro to increase the punching shear resistance of a foundation slab? Or is it possible to arrange vertical stirrup reinforcement in RF‑FOUNDATION Pro?


Answer:
No, it is not possible to arrange punching shear reinforcement in RF‑FOUNDATION Pro. First, the add-on module calculates the longitudinal reinforcement required for the bending design of the slab. From this longitudinal reinforcement, the longitudinal reinforcement ratio is determined, which is subsequently applied to the determination of the punching shear resistance of the slab. If the punching shear design is not fulfilled, you can adjust the provided longitudinal reinforcement in Window 2.4 or Window 2.5 and select another reinforcement proposal with a higher reinforcement content. After the recalculation with the modified reinforcement, you can check in Window 2.2 Governing Design whether the increase of the longitudinal reinforcement was effective. If increasing the longitudinal reinforcement in the foundation slab was not effective, you can still use the design option in the RF‑PUNCH add-on module. In RF‑PUNCH, you can analyze point-shaped punching on foundation slabs. Punching shear reinforcement in the form of vertical or inclined bars can also be applied here.
