Steel Structural Floor Slab

Floor systems used in steel frame structure construction.

Steel structural floor slab.

There are various types of floor systems which can be used in the steel frame structure construction. 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. Advanced floor concepts delivers all three. 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.

A wood or concrete structural floor alleviates the worry of slab movement due to expansive collapsible soils beneath floor slabs. Floors are commonly installed as the beams are erected. The time worn axiom is pick any two. 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.

Speed quality or price. For the system to be practical flexible and efficient the standard structural tee wt and a thick and narrow flange plate are selected. An added benefit is that some forms of shallow floor construction inherently achieve composite interaction between the beams and slab thereby enhancing structural efficiency. The composite steel concrete section consists of an inverted structural tee wt a steel plate and a standard steel concrete composite slab figure 3.

A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. 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. A typical slab was 4 inches to 5 inches thick although 3 inches thick can be found in many old buildings. 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.

Structural floor steel joist with a wood deck structural floor steel beams metal deck and concrete structural floor concrete slab over metal deck and structural void structural garage floor steel beams metal deck and concrete. Three worked examples of precast unit floors in different building types are also included. Steel reinforced slabs typically between 100 and 500 mm thick are most often used to construct floors and ceilings while thinner mud slabs may be used for exterior paving see below in many domestic and industrial buildings a thick concrete slab supported on. Precast concrete slab placed on structural steel frame.

Isolation of the floor system allows it to function without being influenced by the soil strata below. We can provide floor systems constructed of wood or steel support with a concrete or wood floor surface. 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. Touching a sample piece of cinder slab in the field feels like a piece of pumice stone.
