Hobbs Point in Pembroke Dock on the south side and Neyland on the north side are less than 1 mile (1.6 km) apart across the waterway but to drive from one to the other, a journey of 28 miles (45 km) by road was required. Between 1858 and 1950, the Admiralty permitted operation of steam ferries between the two towns. From 1950, the County Council operated a ferry service, with capacity for 24 vehicles and 250 pedestrians. Several factors caused the West Gate Bridge collapse. In summary the proposed construction technique required that the steel box girders be constructed in two separate .
Construction was immediately halted, though within 18 months, other box-section bridges collapsed in Australia and Germany with deadly consequences. An inquiry made a number of safety.Two years into construction of the bridge, at 11.50 am on 15 October 1970, the 112m (367.5 ft) span between piers 10 and 11 collapsed and fell 50m (164 ft) to the ground and water below.. Fifty years ago, on 15 October, 1970, at 11.50am, 2000 tonnes of concrete and steel on the West Gate Bridge site buckled and crashed to the ground; 35 men died. It remains Australia’s worst construction disaster. A .

The project is located in Milford Haven, Pembrokeshire, Wales, United Kingdom, . . Errors in the box girder .The steel box girder bridge, because of its structural efficiency and aesthetics, has become increasingly popular as a bridge type. Because of four unfortunate erection accidents of box girder bridges in Austria, the United Kingdom, Australia, and Germany, this type of structure has received much recent attention. However, because of this attention, the behavior of steel box .

To model the steel box girder, 4-node shell element (S4R) was used. The modeling of the girder was simplified as much as possible because the analysis aimed to investigate reaction force trends according to construction stages. . In the bridge collapse considered here, the total height of girder was more than twice the distance between two .Steel box bridge girders generally exhibit both aesthetic appeal and structural efficiency [1]. Designed with single-cell or multi-cell cross-sections, steel box bridge girders have the advantages of being lightweight, possessing high torsional stiffness, and allowing for rapid erection [2]. . The fact that shear buckling failure triggered . In the 1970s, several steel bridges in Europe collapse due to the local buckling of stiffened plates and steel box girders, causing a shock in the field of bridge engineering [7].Subsequently, numerous investigations on the stability behavior of steel plates and steel box girders are conducted by many scholars worldwide, such as Ichizou et al.

In an experimental study conducted by Van Pham et al. on a three-span steel box girder bridge, it was demonstrated that a complete fracture in one girder did not lead to the collapse of the entire bridge. In conjunction with the intact girder, the structure’s deck proved instrumental in providing stability and retaining the load-resisting .
The continuous box-girder superstructure includes a 10-m-wide top slab with 300 mm effective slab thickness and two continuous-steel box-girder deck system. The box girder is 1.545 m deep. Unconfined strength of concrete is considered to be M45 in the deck, and Fe 415 D is supposed to be characteristic strength in the reinforcing steel.

Construction of the box-section bridge was put on halt immediately. . Following an inquiry, a number of safety recommendations were made, which included the addition of 500ft of extra steel to strengthen the bridge. In 1995, on the 25th anniversary of the disaster a memorial plaque to the four men who died, William Baxendale, George Hamilton . This study evaluates the fatigue performance of the steel-UHPC deck with a thin polymer overlay (TPO) in the Yichang Yangtze River Highway Bridge, a long-span suspension bridge, under static load . For this purpose, the simply supported single-span twin steel box girder bridge with a span length of 36.6 m (120 ft) tested at the University of Texas at Austin was selected as a model to develop a framework and procedure for establishing performance target for the design and safety assessment of twin steel box girder bridges and the paper .

The bridge model used in this paper is a three-span curved steel–concrete composite box girder bridge, and the plane layout of the girder is shown in Fig. 1. The girder is in the form of a single box with a double chamber, the radius of the curvature is 210 m, each span length is 25.6 m, and the central angle of the three-span girder is 21°.
The main bridge is a 5-span continuous cable-stayed bridge with cable tower and steel box girder double cable plane. Its cross-border arrangement is 63 m + 257 m + 648 m + 257 m + 63 m=1288 m.
Rules implemented in the wake of the disaster laid the foundations for a new standard in box girder bridge design and the Cleddau collapse was regarded as the last major bridge disaster in the UK .bridge deck explosions, the main energy dissipation components of steel girders are the bridge panel, web, diaphragm and rib stiffeners. The research results can provide the basis for the follow-up study on the anti-explosion safety of bridge structures. Keywords: Cable-stayed bridge, steel box girder, deformation response,

Google Scholar. Chang, S. T. 2004 . The local stability may dominate the design of a self-anchored suspension bridge with steel box girders.Due to geometric imperfections and welding residual stresses rarely considered for its ultimate bearing capacity analysis, the influences of the local buckling on the global structural behavior remain unknown. This paper presents a multi-scale finite element .
A three-span continuous bridge located in Miami, FL, was selected to represent continuous twin steel box girder bridges in this study. The bridge was built in 2005 and has an overall length of 208 m and out to out width of 10.25 m carrying one traffic lane. The first and last span length is 64 m, and the middle span length is equal to 80 m. The bridge is a continuous four-span steel box-girder with a total length of 147.88 m with spans of 28.5, 31.2, 32.576, 31.4, and 24.2 m shown in (Fig. 4). The steel box-girder superstructure has a top slab width of 10 m and a two-steel box girder/deck system. The effective slab thickness is considered as 300 mm and tub-girder depth is 1.545 m.
The analysis process was illustrated using two typical bridge configurations: A two-box steel girder bridge and a steel truss bridge. The box girder bridge is assumed to be susceptible to fatigue fracture at the midspan of one box and the truss is assumed to lose the load carrying capacity of a main strut.of steel box girder bridges. INTRODUCTION Box girders have become a prominent element in the con struction of major river crossings, highway interchanges, and transit systems. These types of structural elements are particularly attractive because of their high torsional stiffness, which is required when the bridge is curved.
