Structural Slab Level Vs Structural Floor Level

The structural slab usually is at the same level throughout except when required to have a drop in level due to drop in ffl or due to structural design.

Structural slab level vs structural floor level.

Ssl structural slab level. And not being able to slope a variable thickness floor. This video compares and contrasts the differences between 3 floor types. Screeding or concrete topping or mortar or substrate usually accommodates the difference between the structural slab and the floor finishes.

The ultimate goal is a flat level slab. Typically highways and parking lots along with most industrial warehouse and commercial floor slabs are designed with plain structural concrete. Plain concrete slabs will be thicker than structural slabs yet in most cases cost effective compared to structural slabs. The average person can sense if a floor slopes 1 inch in 10 feet and sloping floors or sagging floors are often one of the warning signs that structural engineers look for when analyzing a house.

To ensure this minimum thickness is achieved the steel beams are undercambered intentionally. We know the steel will deflect under the weight of the wet concrete and because the slabs are often ul rated the design slab thickness is a minimum thickness to achieve the necessary fire resistance. These slabs will contain steel reinforcing rebar or post tensioning tendons. Floor finishing level is the final reduced level of the flooring level tiles marble.

Although most floors slope it is important to know how much and why. The architectural floor the arch structural floor and the concrete slab. Ssl structural slab level is typically more used within the industrial and commercial markets and is very simply the level of which the structural concrete floor slab would finish however the term ssl is only use if there was to be other finishes to be placed over the structural slab. The steel provides.

Ffl finished floor level.
