Dear All,
Has anyone experienced a design and constructed of Continuous-Segmental Box Girder Superstructure ?
I am doing one project, in India and have some specific questions related to design and execution of the same.

As insisted by a few colleagues and friends, I am elaborating the questions as below :-
Q.1. Has anyone done continuous segmental bridges without a 'Wet-Joint' ?
Q.2. If yes then how the segment movements (elastic shortening / shrinkage / creep etc.) were addressed at design and execution stage? How the segment casting done ?
Q.3. Were the couplers used ? If so then in inclination position or the cables were flat ?
Q.4. What was the provision made in the bearings and the pedestals to allow for the tolerance (errors) in casting and the moments during placement of superstructure ?
Q.5. How the synchronisation was done / achieved between the segments cast in yard vs. the piers cast at site ?
Q.6. How the provision was made for curvature and longitudinal-gradient and super elevation?
