  2. Precast concrete - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete

    Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels, floors, roofs, and piles.

  3. Double tee - Wikipedia

    en.wikipedia.org/wiki/Double_tee

    The floor systems are mostly built from pre-topped double tees. This system evolved from the earlier use of tee systems where the flanges of the T-beams were connected. The concrete is then poured at the top of the tees during the construction to create the floor surface, hence the process is called field-placed concrete topping.

  4. Lift slab construction - Wikipedia

    en.wikipedia.org/wiki/Lift_slab_construction

    This method of construction simultaneously began development in 1948 by both Philip N. Youtz of New York and Thomas B Slick of Texas. Although the first patent for lift slab construction was given to Slick in 1955, the method of construction is commonly referred to as the "Youtz-Slick Method". [1]

  5. Voided biaxial slab - Wikipedia

    en.wikipedia.org/wiki/Voided_biaxial_slab

    Hollow-core slabs, also known as voided slabs, initially appeared as one-way elements in Europe during the 1950s, and are still commonly manufactured in precast form for applications where fast construction and low self-weight are required. [2] [6] Waffle slabs are a common type of hollow-core slab which use the same principle as voided biaxial ...

  6. Falsework - Wikipedia

    en.wikipedia.org/wiki/Falsework

    The illustrations are of modern pipe-column falsework, used to support the formwork for a post-tensioned reinforced concrete flyover connector for the eastern span replacement of the San Francisco-Oakland Bay Bridge. When the supports are complete, wood beams and plywood or reusable metal forms will be placed, reinforcing and tenon conduits ...

  7. Tilt up - Wikipedia

    en.wikipedia.org/wiki/Tilt_up

    This roof system is one of the most commonly used systems in commercial buildings, including those with masonry walls, precast concrete walls, and almost all forms of wall construction. The Tilt-Up concrete panels performed very well and survived the extreme loads of the EF-5 event only to collapse after the roof failed due to lack of bracing ...

  8. Anchor bolt - Wikipedia

    en.wikipedia.org/wiki/Anchor_bolt

    A connection between structural elements can be represented by steel columns attached to a reinforced concrete foundation. [4] A common case of a non-structural element attached to a structural one is the connection between a facade system and a reinforced concrete wall. [5]

  9. Precast concrete lifting anchor system - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete_lifting...

    The rigging arrangements can influence the applied anchor load, where statically indeterminate systems are not necessarily a design consideration, but can be used in practice. The determination of the loads through the rigging system must be a consideration whilst calculating the load resistant model, refer to the examples shown in Figure 3.
