  2. Diaphragm (structural system) - Wikipedia

    en.wikipedia.org/wiki/Diaphragm_(structural_system)

    Diaphragms are usually constructed of plywood or oriented strand board in timber construction; metal deck or composite metal deck in steel construction; or a concrete slab in concrete construction. [1] The two primary types of the diaphragm are flexible and rigid. [1]

  3. Shear wall - Wikipedia

    en.wikipedia.org/wiki/Shear_wall

    A typical timber shear wall consists of braced panels in the wall line, constructed using structural plywood sheathing, specific nailing at the edges, and supporting framing. A shear wall is an element of a structurally engineered system that is designed to resist in- plane lateral forces, typically wind and seismic loads.

  4. Wood warping - Wikipedia

    en.wikipedia.org/wiki/Wood_warping

    Different types of wood warping. Wood warping is a deviation from flatness in timber as a result of internal residual stress caused by uneven shrinkage. Warping primarily occurs due to uneven expansion or contraction caused by changes in moisture content.

  5. Cast-in-place concrete - Wikipedia

    en.wikipedia.org/wiki/Cast-in-place_concrete

    Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [2] It uses concrete slabs for walls ...

  6. 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 ).

  7. Drywall - Wikipedia

    en.wikipedia.org/wiki/Drywall

    Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...

  8. Properties of concrete - Wikipedia

    en.wikipedia.org/wiki/Properties_of_concrete

    Concrete can also be prestressed (reducing tensile stress) using internal steel cables (tendons), allowing for beams or slabs with a longer span than is practical with reinforced concrete alone. Inspection of existing concrete structures can be non-destructive if carried out with equipment such as a Schmidt hammer , which is sometimes used to ...

  9. Hollow-core slab - Wikipedia

    en.wikipedia.org/wiki/Hollow-core_slab

    The precast concrete slab has tubular voids extending the full length of the slab, typically with a diameter equal to the 2/3–3/4 the thickness of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight also lowers material and transportation costs.
