This web application conducts check on punching for Flat slab or Post-tensioned slab with/out shear reinforcement. The punching check is conducted using the following approaches:

Approach 1:

Using Simplified Method at Section at d/2 and Simplified Method at Outside Stirrups Section

* In Simplified Method, a β-factor is used instead of considering the applied moment at the punching critical section.

Approach 2:

Using Detailed Method at Section at d/2 and Simplified Method at Outside Stirrups Section

* In Detailed Method, Punching stresses are estimated considering the applied moment at the punching critical section in addition to the axial load, without including β-factor.

* Design Code: Egyptian Code (ECP 203-2020), or American Code (ACI 318-2022).
