The bridge is a three-span steel composite I-girder bridge with a total length of 206.5m. The main span is 73.5m long and the side spans are 66.5m long. This bridge is supported by abutments at both ends and two large piers with 8 piles each between spans.Load Steel Box Girder Bridge.mcbz file to load bridge model 2.Load File 1 Initial Set-up 3. https://www.midasoft.com MIDAS CIM Steel Box Bridge 3.Modify Layout . For Row 3, change type from straight to Arc and apply radius if 150 on column R 5 2 2 1. https://www.midasoft.com MIDAS CIM Steel Box Bridge 3.Modify Layout This feature makes the study of the vibration and noise of the bridge type more complicated. Therefore, in this paper, the characteristics of vibration and noise radiation of a high-speed railway steel–concrete composite box girder bridge are studied in detail from two aspects: the theoretical basis and a numerical simulation.
The safety evaluation of single-tower steel box girder bridges over the sea includes various factors, including the steel box girder, concrete main tower, main cables, suspension rods and others . This study is based on a proposed steel box-girder bridge that would be part of an urban elevated system. The upper structure of the main beam is a 48 m +60 m +48 m steel box girder. The full width of the bridge is 13.5 m, and the steel box girder adopts a single box double chamber section. The bridge layout is shown in Figure 1.

42. 42 Box Girder Bridges For spans greater than around 45 metres, pre- stressed concrete box girders are the most common method of concrete bridge construction. The main spans are hollow and the shape of the 'box' will vary from bridge to bridge and along the span, being deeper in cross-section at the abutments and piers and shallower at mid span.
In the FEM, the stiffeners, steel diaphragms in steel boxes, and K-type steel diaphragms between steel boxes were modelled with Shell 63 element, and other components, including end diaphragms, the concrete deck and the steel box girders, were modelled with Solid 45 element, as shown in Fig. 2. The interaction between adjacent components were .
opportunities to further enhance steel box girder technology. Combinations of steel boxes and concrete boxes, posttensioned decks, single box girder bridges, multiweb and multicell boxes are all design and construction options that have potential. For the evolution of steel box girder bridges to continue, researchers,For railways, construction depth is usually very tightly constrained and half through construction must be employed. One option is then the Network Rail ‘Standard Box Girder’. The Network Rail Standard Box Girder type bridge that . 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. [8], Frieze [9], . The concrete box girder is one of the most commonly used structure forms for bridges because of its large flexural and torsional stiffnesses. However, with the increase of span length, the self-weight of a concrete box girder may increase rapidly, which restricts its use in long-span bridges [1].One of the most promising ways to reduce the self-weight of bridges is to .
