  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

    The method was first used at Trinity University in San Antonio, Texas during the construction of Northup Hall in 1952. [2] Northrup Hall was the first full scale building erected using lift slab construction. Being such, the process drew a crowd of spectators, waiting to see if the structural integrity of the building would hold. [3]

  5. Moment-resisting frame - Wikipedia

    en.wikipedia.org/wiki/Moment-resisting_frame

    Moment-resisting frame is a rectilinear assemblage of beams and columns, with the beams rigidly connected to the columns. Resistance to lateral forces is provided primarily by rigid frame action – that is, by the development of bending moment and shear force in the frame members and joints. By virtue of the rigid beam–column connections, a ...

  6. 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]

  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. Expansion joint - Wikipedia

    en.wikipedia.org/wiki/Expansion_joint

    Pipe expansion joints are necessary in systems that convey high temperature substances such as steam or exhaust gases, or to absorb movement and vibration. A typical joint is a bellows of metal (most commonly stainless steel ), plastic (such as PTFE ), fabric (such as glass fibre) or an elastomer such as rubber .

  9. Load-bearing wall - Wikipedia

    en.wikipedia.org/wiki/Load-bearing_wall

    Column – in most larger, multi-storey buildings, vertical loads are primarily borne by columns / pillars instead of structural walls; Tube frame structure – Some of the world's tallest skyscrapers use load-bearing outer frames – be it single tube (e.g. the old WTC Twin Towers), or bundled tube (e.g. the Willis Tower or the Burj Khalifa)
