special uplift bearings

[ukengineer58]

Hi there, returning to these excellent forums after a long hiatus and was hoping for some more helpful advice. Has anyone used uplift bearings to replace elastomeric bearings in a bearing replacement scheme? The reason I am looking at it is that we presently have arrestor bars cast into a PT deck/ballast wall which are not in a good condition. We would like to avoid drilling into the PT deck ends to install new bars to provide uplift resistance at the deck ends.

I'm not sure about details of it, but you'd better check out chapter 26 of Bridge Engineering Handbook
