Self-supporting structure floors and floors for mixed steel and concrete collaborating construction.

The mixed steel and concrete collaborating floor can perform:

1) Anti-seismic behavior
2) Resistance – Load-bearing capacity
3) Stiffness – vibration containment
4) Load distribution
5) Acoustic insulation
6) Fire compartmentalization
7) Thermal inertia
8) Lightness
9) Economy
10) Aesthetic value and maintenance of historical and cultural value

The floors must perform the function of distributing horizontal actions, therefore they must be well connected to ensure adequate diaphragm operation.

The mixed structure floors can be considered infinitely rigid in their plane, provided that they are made with a reinforced concrete slab of at least 40 mm thickness.
