WARWICKSHIRE SKEW TWIN BOX GIRDER BRIDGE

This article gives an outline of the design and construction of the Warwickshire skew twin box girder bridge on the Kenilworth By Pass. It is the central bridge in the 3-level interchange connecting the by pass and the A45 truck road. The authors briefly discuss the factors that led to the choice of a single-span skew bridge at this site, rather than three-span structures or by over-spanning with a single-span structure. They follow this with details of the bridge itself which involved a displacement of the box girder units by 3.68M each due to the 30 degree skew. An account is given of the method of analysis used in designing the structure, which was broken down into four parts to facilitate the writing and checking of the computer programs used, and to make it easier to re-run the program until A satisfactory solution was obtained. The article concludes by giving constructional details. These mainly relate to the freyssinet concrete hinges that support the legs, the design of which was complicated by the need to resist torsion about the longitudinal axis perpendicular to the line of the hinges, in addition to the normal loads. /TRRL/
