Fifty-one people were killed in these failures, leading in the UK to the formation of the Merrison Committee [4] and considerable investment in new research into steel box girder behaviour. Most of the bridges still under construction at this time were delayed for investigation of the basic design principle.
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
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.
Infrastructure includes the basic physical and organizational structures needed for the operation of a society or enterprise, [1] or the services and facilities necessary for an economy to function.
The report led to the development of British Standard 5975: 1982 Code of practice for falsework, the first for falsework. [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]
It expanded rapidly in formwork and scaffolding under GKN ownership in the end of the 1980s. [2] In June 2000, GKN Kwikform merged with RMD (Rapid Metal Developments, established in 1948), the formwork and scaffolding unit of RM Douglas (part of Tilbury Douglas), to form RMD Kwikform. [3] [1] Tilbury Douglas renamed itself Interserve in 2001. [4]
Failure Reporting (FR). The failures and the faults related to a system, a piece of equipment, a piece of software or a process are formally reported through a standard form (Defect Report, Failure Report). Analysis (A). Perform analysis in order to identify the root cause of failure. Corrective Actions (CA).
