Anyone know what the tie load would have been? The SHM paper leads me to think it's nominally around 6000kip per tie.
So then is the 3000kip post-tension load on the rods meant to take just half the load off the damaged member? I suppose that is a possibility.
waross, the answer is probably both, and that's covered pretty well in the Structural Health Monitoring Paper (link above in post by 3DDave).
a pdf on the retrofit which shows some of the post-retrofit bearings:

The original design...
∧ Note the curved cut traced out for specimen "2B"; they must think there's still load flowing through that inboard plate, and so do I.
Based on the photos posted by IRstuff above on that weld seam split, and the photos of the rest of the crack, I'm thinking the tie never had its load...
