Precast beam to bridge abutment connection
Precast beam to bridge abutment connection
(OP)
Does anyone have any good references on the detailing or design of precast tee beam girders to abutment connection? I may have a single span prestressed girder project project coming up where we'll be responsible for this connection detail and I can't seem to find a good reference on the typical details used.
Seems like steel girders are much more common when it comes to examples of this connection. Not something I'd like to reinvent the wheel on if I don't have to.

I lied....it exists and is alive and well.

Nice detail, that's exactly what I was hoping to find. Our DOT also has gone away from double tees but this is a non-DOT job, and as we don't own the forms for NEXT beams or bulb tees making a down and dirty tee or double tee girder in our stressing bed seemed like the easiest way to go. Adding a weld plate wouldn't be hard at all and I think the contractor might actually like it.
I also just rediscovered this website and will have to go through it again for useful nuggets of info: https://www.fhwa.dot.gov/bridge/prefab/if09010/02c.cfm#d4
Not a bad thought at all. The precast double tees for buildings and parking garages love their embedded weld plates connection which fits with what BridgeEI was thinking above. Those don't usually have an elastomeric pad but I think that's just the inherent differences between a bridge girder and a garage floor beam.
