uplift bearing design
uplift bearing design
(OP)
We are designing a bearing for bridge. The uplift force and shear force are about 100k. How to anchor bearing to concrete abut. and deck?
AASHTO code or ACI code?
Any reference books?
Thanks,

1. Entire compatibility with any other thing demanded of the bearing, to avoid the connection be damaged by forfeiting some relevant issue. You surely do not waht your anchor be damaged by, say, thermal expansion.
2. Proper transfer of the force and lengths of embedment to each side of the interface.
3. Block shear check on that once transferred to the superestructure and abutment, the mechanical properties there and standing solicitations indicate that the forces have been positively and safely transmitted between sides of the interface without any negative impact on the standing design.
4. Equilibrium of the tensile force.
You will find some info in the Xanthakos' books on bridges
Theory and Design of Bridges
Bridge Substructure and Foundation Design
I think to remember Leonhardt's book on prestressed concrete had fanciful details on actual anchors of significant forces by hoops.
And of course whatever you may find on cantilever or suspended bridges.
