i am working on replacement of only one of the prestressed girders of a multi girder 50 year old bridge!!
the new deck load is going to be less than the existing
the new deck concrete is as strong as the old girder concrete
to arrive at the same LiveLoad deflection
to TRY and minimize the or if possible eliminate creep in new girder so the interaction with thw existing in the long run wont be detrimental to the deck slab
How and what would you guys do and what else must be considered
suggestions are much appreciated
