NEW BRIDGE OVER RIVER CAM

The article describes the design and construction of the new motorway bridge in Cambridgeshire built on poor ground conditions, which had to be aesthetically pleasing, and be completed within 26 months. A cantilever and suspended span with half joints was chosen using standard transversely post tensioned box beams. The suspension span was designed as floating on rubber bearings, the columns supported on fixed spherical rocker bearings and the ends of the side spans on laminated rubber bearings with conventional piled abutments. Three-dimensional grillage analysis was used to design the in-situ concrete side spans with integral piers. Manual and computerised techniques were employed to design the suspended span. The complicated reinforcement within the piers required very accurate bending and fixing. Framework and falsework for the in-situ piers and end spans required a double skinned shutter held together with steel yokes supported from scaffolding. Details are given of the half joint assembly. /TRRL/
