Hi,
I have to replace the two convertible spherical bearings at bent/piers. For that purpose, I have to lift the multi cell box section deck (width of 16.15m rested on two piers with free spherical bearings) during construction up to 20 mm using 04 no jacks placed on pier head. Side spans are 58m with fixed & transversely guided bearings and 40 m with free and longitudinal guided bearings. I need to know the required design and stability checks during this jacking and bearing replacement event to submit to the consultant, please. Thanks
