  2. Falsework - Wikipedia

    en.wikipedia.org/wiki/Falsework

    Completed falsework: Decking and some formwork has been added. 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 ...

    Structural failure — support piers collapsed 7 killed, 0 injured Complete failure of two spans on I-5 Due to extreme rainfall, the Arroyo Pasajero experienced high volumes of water at high speed. This caused scouring of the river bed undermining the support piers of both spans. Elhovo bridge over the Tundzha river [43] Elhovo, Yambol Province

    A wooden deck was then erected atop the falsework to support the lowest forming surface. Reinforcing for the lowest surface of the box structure was then added, and the concrete was poured. During the initial pour, reinforcing and formwork for interior shear beams and any included tendon conduits were added. Later, another concrete pour was ...

    This is a list of structural failures and collapses of buildings and other structures including bridges, dams, and radio masts/towers. This is a dynamic list and may never be able to satisfy particular standards for completeness.

    [3] [5] BS 5975 required appointment of a falsework co-ordinator on sites required to allocate design responsibility and ensure that a design was checked. [6] Since the adoption of the standard there have been no large-scale failures of falsework systems in the UK. [7]

  7. Box girder bridge - Wikipedia

    en.wikipedia.org/wiki/Box_girder_bridge

    For steel box girders, the girders are normally fabricated off site and lifted into place by crane, with sections connected by bolting or welding. If a composite concrete bridge deck is used, it is often cast in-place using temporary falsework supported by the steel girder.

  8. Cantilever bridge - Wikipedia

    en.wikipedia.org/wiki/Cantilever_bridge

    A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.

  9. Shoring - Wikipedia

    en.wikipedia.org/wiki/Shoring

    Shoring is designed to prevent collapse where shielding is only designed to protect workers when collapses occur. Concrete-structure and stone-building shoring, in these cases also referred to as falsework, provides temporary support until the concrete becomes hard and achieves the desired strength to support loads.
