Concrete Pouring Methodology

[bimal]

What should be the methodology for pouring concrete for the construction of a box girder bridge of simply supported span of 52 m over a river using truss supported scaffolding which would flex considerably during concreting?

 

[Hariharan]

Compute the deflection of the truss and the camber required in the
girder, the sum will be the requisite camber in the truss.
Provide the requisite camber to the scaffolding, so that the final
deflected shape of the bridge girder would have the requisite camber.
Be careful about concreting sequence.
