2. Content
Punching shear design and check
Code dependent deflection CDD

3. WHY?

4. Design and check of punching shear
What’s supported?
Punching check and design for slabs and foundations
Automatically recognition of support shape and location
Different possibilities for the calculation of β factor
Two different types of reinforcement are supported for the checks of slab resistance
Presentation of UC and size of critical control parameter.
Calculation of punching reinforcement where necessary.

5. Punching shear (Design and Check)
Concrete resistance
Check if the concrete is strong enough alone
Concrete and reinforcement resistance
If not, check if the amount of reinforcement is reasonable
Design of punching reinforcement
Design reinforcement if reasonable, if not, change form of structure

6. New automated workflow
Modeling
Load combinations
Analysis
Run punching check + check
