  2. Orthotropic deck - Wikipedia

    en.wikipedia.org/wiki/Orthotropic_deck

    The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels.

    en.wikipedia.org/wiki/Insulating_concrete_form

    The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...

  4. Waffle slab - Wikipedia

    en.wikipedia.org/wiki/Waffle_slab

    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), because, for a given mass of concrete, they are much stronger than flat slabs, flat slabs with drop panels, two-way slabs, one-way slabs, and one-way joist slabs.

  5. Reema construction - Wikipedia

    en.wikipedia.org/wiki/Reema_construction

    Reema construction is a system of building using prefabricated reinforced concrete panels which came into being in the late 1940s and was still in use well into the 1960s. Buildings made in this way are currently (2008) very hard to obtain finance on in the UK, primarily due to potential problems with similar large panel system construction ...

    en.wikipedia.org/wiki/Autoclaved_aerated_concrete

    Accuracy: Panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before leaving the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is less use of finishing materials such as mortar.

  8. Deck (bridge) - Wikipedia

    en.wikipedia.org/wiki/Deck_(bridge)

    A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck.
