Segmental Bridge Design

Segmental Bridge Design

Segmental Bridge Design

(OP)
Hi Good Day Everyone,

I have been doing PT flat slab, beam slab design for 3 years. Now I have come across a segmental PT bridge design so I would very much like to learn and study. We have a site guy who has decades of experience on this type of construction. And it would be great if you could share design book or manual or work examples on this if possible to Eurocodes.

Apart from the usual PT design considerations, what are the special things to take care of?

Shear Design? by indentation and axial prestress?
Careful consideration of construction stage design and deflections for balance cantilever construction before the two segment meet at mid-span?

Thanks

We have a site guy who has decades of experience on this type of construction.

I would spend some considerable time ON SITE right next to this guy and learn, and concurrently review the applicable EU segmental bridge design code/s and maybe go over some past drawings/calculations of such bridges.

I am not familiar with EU codes, but in the US the FHWA (Federal HighWay Administration):Link has free PDF downloads of manuals, reports, and sample calcs/drawings for some concrete bridge structures - not sure if they cover segmental PSC bridges.

Also ASBI (American Segmental Bridge Institute): Link and PCI (Precast/Prestressed Concrete Institute): Link

RE: Segmental Bridge Design

Attached is an example based on AASHTO LRFD, different code but stress is stress and the bridge won't know if it's in Europe or the US.

I worked on one segmental bridge about 15 years ago; came in at the tail end of the job. I was detailing the segments; seemed like there was a lot of shear reinforcement.

Thanks for all the links.
Yes, I will spend time right next to that guy and will definitely go over all some past design and drawings.

Totally agree! But sadly most people here wont think so and accept the calculation. Appreciate much for help.

Thanks

aungthu13490 - what I meant to say, from an academic standpoint - to learn how to design this type of bridge - the design principles are the same regardless of the codes.cheers
