  2. Voided biaxial slab - Wikipedia

    en.wikipedia.org/wiki/Voided_biaxial_slab

    The overall mass of concrete can be reduced by 35–50% depending on the design, [1] as a consequence of reduced slab mass, as well as lower requirements for vertical structure and foundations. Biaxial slabs commonly span up to 20 metres at a thickness of around 500 mm. [ citation needed ] The added strength also reduces the acoustic ...

    en.wikipedia.org/wiki/Lift_slab_construction

    Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

    A matching pair of these doors is called a French window, as it resembles a door-height casement window. When a pair of French doors is used as a French window, the application does not generally include a central mullion (as do some casement window pairs), thus allowing a wider unobstructed opening. The frame typically requires a weather strip ...

    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). [1] [2]

    en.wikipedia.org/wiki/Frame_and_panel

    The basic idea is to capture a 'floating' panel within a sturdy frame, as opposed to techniques used in making a slab solid wood cabinet door or drawer front, the door is constructed of several solid wood pieces running in a vertical or horizontal direction [1] with exposed endgrains. Usually, the panel is not glued to the frame but is left to ...

  7. Tilt up - Wikipedia

    en.wikipedia.org/wiki/Tilt_up

    Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete. Though it is a cost-effective technique with a shorter completion time, [ 1 ] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings.
