Bridge Deck Negative Moment Region Pour
Bridge Deck Negative Moment Region Pour
(OP)
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.

We had a problem a few years ago on a staged deck placement. The people who designed it didn't take into account staged construction and the deck closure was off by 4".
