Segmental Box Girder Analysis
Segmental Box Girder Analysis
(OP)
Has anybody read “Precast Segmental Box Girder Bridge Manual”, Post-Tensioning Institute and Prestressed Concrete Institute???
I got a question about distribution of BM after a joint is formed to connect two erected spans.
Refer to Fig 3.18 (b), Step 3 on page 39, it shows that all erected spans are connected and the BM at joint B is 1472 k-ft. I know how to work out the BMs at the interior supports and the joint at midspan. However, I have no clue how to do it for joint B in the tail spans.
Thanks!!!

RE: Segmental Box Girder Analysis
but I'm interested in getting this book.
Is it published in 1978?
Where can I buy it??
Looking forward for Your replay,

How to calculate the bending moment when construction is completed:
1. Have a continuous beam of the finished stage. Do NOT apply any dead load on the structure.
2. Apply vertical dead load only for the range A-B and F.G
3. Add the moment obtained to that in Fig. 3.18 (b) Step 1.
4. You get Fig. 3.18 (b) Step 3.

Thanks for your advice.
krakordian,
I just have the electronic copy. I got the file from my "boss" so I don't know where it comes from....I think you are right, this book might be published in 78's because a lot of prestressing techniques mentioned in this book was developed in the 60-70's
