Bridge Deck Pour in Negative Moment Region

Bridge Deck Pour in Negative Moment Region

Bridge Deck Pour in Negative Moment Region

I am a surveyor for a bridge construction company in the northeast...our current project is the construction of a five span steel plate girder bridge. It consists of 8 beams on 12' centers, and a staged joint on the 3rd girder...no closure pour. During the deck placement process, after all the positive regions were poured, we consistently had issues tying back into the bulkhead from the previous pour in the positive region. Either we would end up "ramping" down into the bulk head on either side or "ramping" up. It never seemed to tie in smoothly. I was curious if anyone has experienced this and can possibly offer an explanation or advice.

Thanks a lot, any help would be appreciated.


RE: Bridge Deck Pour in Negative Moment Region

Appears to be, and I am guessing, not enough camber on the beams or not enough beams either in number or depth or all of the above. Whatever the reason it seems too much deflection.
