Steel Structural Floor Slab
A wood or concrete structural floor alleviates the worry of slab movement due to expansive collapsible soils beneath floor slabs.
Steel structural floor slab. In a structural concrete slab the thickness of the slab is not a factor in. Speed quality or price. Touching a sample piece of cinder slab in the field feels like a piece of pumice stone. Advanced floor concepts delivers all three.
Precast concrete slab placed on structural steel frame. There are various types of floor systems which can be used in the steel frame structure construction. The time worn axiom is pick any two. This light weight resulted in a material savings for the steel frames and foundations making it very appealing as a floor slab system.
For the system to be practical flexible and efficient the standard structural tee wt and a thick and narrow flange plate are selected. The floor slab may be in the form of a precast concrete slab or a composite slab with metal decking either shallow or deep decking may be used. A structurally reinforced slab on ground uses a composite of concrete and structural steel to support the design load structural steel may be rebar or wwf. Structural design guidance provided in previously published three sci publications design of composite beams using precast concrete slabs p287 design of asymmetric slimflor beams with precast concrete slabs p342 and.
Three worked examples of precast unit floors in different building types are also included. At this stage when the steel mesh and trench mesh are in position call in for a steel inspection by either the local council or structural engineer to approve the steel in position. Floor systems used in steel frame structure construction. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete.
The floor slab mesh should overlap the next floor mesh with a minimum of 450mm to provide an uninterrupted top layer of floor mesh over the entire concrete floor. An added benefit is that some forms of shallow floor construction inherently achieve composite interaction between the beams and slab thereby enhancing structural efficiency. Isolation of the floor system allows it to function without being influenced by the soil strata below. A typical slab was 4 inches to 5 inches thick although 3 inches thick can be found in many old buildings.
The composite steel concrete section consists of an inverted structural tee wt a steel plate and a standard steel concrete composite slab figure 3. Floors are commonly installed as the beams are erected. The cross sectional area of the steel is inserted into engineering formulae found in aci 318 to determine the load carrying capacity for a given slab design. Design of multi storey braced.
