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.1.07 Use of weather resistant steel R5 1.08 Box girder bridges R3 1.09 Comparison of bolted and welded splices R3 1.10 Half through bridges R3 Design - detailing 2.01 Main girder make-up R2 .

Box girder bridges No. 1.08 SCI P185 Guidance notes on best practice in steel bridge construction 1.08/1 GN107R3.doc Revision 3 Scope This Guidance Note gives an overview of the main design issues for steel box girders in short and medium span bridge schemes. SCI-publication P140 (Ref 1) gives a more exten-sive treatment of steel box girder design. In this paper, a large-span cable-stayed bridge with double pylons and double cable planes is employed to study the overall and local mechanical behaviors. The steel box girder bridge is constructed by incremental launching with the maximum span of 50 m. Through the overall stress analysis, the most unfavorable stress position of the structure in the .narrowed down and quickly focused on steel girders because of constructability considerations. Three steel structural types were evaluated: 1) plate girders with integral pier caps, as shown in Figures 2 and 3, 2) a single steel box girder, and 3) twin steel box girders, as shown in Figure 4.
