2. Composite construction - Wikipedia

   en.wikipedia.org/wiki/Composite_construction

   Structural engineering. In structural engineering, composite construction exists when two different materials are bound together so strongly that they act together as a single unit from a structural point of view. When this occurs, it is called composite action. One common example involves steel beams supporting concrete floor slabs. [1]

3. Open web steel joist - Wikipedia

   en.wikipedia.org/wiki/Open_web_steel_joist

   In structural engineering, the open web steel joist (OWSJ) is a lightweight steel truss consisting, in the standard form, of parallel chords and a triangulated web system, proportioned to span between bearing points. The main function of an OWSJ is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to ...

4. Double tee - Wikipedia

   en.wikipedia.org/wiki/Double_tee

   Double tees are connected during the construction without topping with concrete to create the parking structure floor surface. [6] A benefit of pre-topped double tees is a higher quality concrete for more durable surface to reduce traffic wears. Factories can produce the topping with minimum concrete strength of 5,000 psi. In some areas, the ...

5. Steel frame - Wikipedia

   en.wikipedia.org/wiki/Steel_frame

   The central "web" of the steel I-beam is often wider than a column web to resist the higher bending moments that occur in beams. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated mold, below a thick layer of concrete and steel reinforcing bars. Another popular alternative is a floor of precast ...

6. Waffle slab - Wikipedia

   en.wikipedia.org/wiki/Waffle_slab

   A waffle slab or two-way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. [ 1 ] The name waffle comes from the grid pattern created by the reinforcing ribs. Waffle slabs are preferred for spans greater than 40 feet (12 m), as they are much stronger than flat slabs, flat ...

7. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. 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).
