Tie-down Design for Uplift at a Bridge Abutment
Tie-down Design for Uplift at a Bridge Abutment
(OP)
I am designing a bridge for a private party and the span balance is not good. I have uplift at the abutments. I have not seen a detail for a tie-down before and was wondering if someone could shed some light on this. One abutment has around 15 kips and the other is around 2 kips.

It seems the uplift is really small, did you consider adding weight at abutments? If superstructure is integral with abutments? If not, all you need is well-embedded into abutment anchor bolts.
