Each span has nine adjacent type 4B28 box girders that were formed using the side forms of a standard Texas I-girder spaced approximately 4 ft (1.2 m) apart. In November 1971 a steel box-girder bridge across the River Rhine near Koblenz in Germany collapsed killing 12 people. In particular the report focuses on the Milford Haven Bridge in Wales which collapsed during construction resulting in four deaths in June 1970. The bridge was - and is - a box girder design. There have been a number of deadly bridge collapses through the years. In recent years, several accidental collapses of girder bridges have occurred under the influence of eccentric heavy vehicles in China. Photo: Public Record Office Victoria (supplied) It was tasked with investigating the design and construction methods of box-girder … The collapse was attributed to the design of the bridge, in particular the failure of the pier support diaphragm to fulfil its function of lateral stability during erection. Investigating the disasters The British government responded by setting up the Merrison Committee of Inquiry. To explore the causes and mechanisms of the collapses, a collapsed six-span, RC, continuous box-girder bridge was introduced and analyzed. The … The girder ultimately failed and was responsible for the collapse, which ended up delaying the bridge’s opening for three months and leaving four workers with minor injuries. The final cost of construction was £11.83 million and the bridge was opened to traffic on 20 March 1975. The Milford Haven bridge Collapse Introduction This report analyzes and discusses the construction and possible failures of a box-girder supported bridge. Rescuers and workers examine the twisted girders of the West Gate Bridge. Here's a look back at the 10 deadliest incidents in the last half century. girder bridge. These rules laid the groundwork for a new British Standard covering box girder bridge design. The 40-ton bridge beam sheared off the top of a Dodge Durango when the girder collapsed May 15, 2004, instantly killing a family of three from Evergreen. A unique transverse connection that eliminated the need for That means it was built in sections that were trundled along the partially completed bridge and simply lowered onto the front of the construction. As of 2007, the collapse during construction is the last major bridge disaster in the UK. The decisions and events that led to the collapse of Xiaoshan Bridge, and the collapse process itself can be summarized in four stages: (1) The initial design adopted a symmetrical cross-section, for which case the box girder would have been relatively well balanced on its … The 300-ft-long (90 m) bridge consists of four equal 75 ft (23 m) spans with skew angles ranging from 0˚ to 30˚. Associate Professor Caprani says technical lessons from the West Gate Bridge collapse have led to the development of superior steel box girders – they're now used to construct some of the longest bridges in the world.
