As from Diamonds 2019r02, you can choose how the crack formation in the secondary direction (=z’-direction) of preslabs should be calculated:
- either using the total plate thickness
- either using the reduced plate thickness
|Used plate height to calculate crack formation in secondary direction: (e)
This option is less conservative. It is used when the preslabs themselves (e.g. the elements with thickness (1)) have a large width (≈ 240cm) and with joints far away from the critical zones.
|Used plate height to calculate crack formation in secondary direction: (e) – (1)
This is the most conservative option.
