How this node works
The plank bears on the beam with a minimum length; cast monolithically with the topping, the support is closed with continuity (negative-moment) reinforcement that ties the floor over the beam and controls cracking.
Key points
- Bearing beam / ring beam
- Plank (predalle) bearing
- Minimum bearing length
- Collaborating topping
- Continuity reinforcement (negative moment)
- Anchored girder
