Multi-rotational Bridge Bearings - AASHTO LRFD Specifications - FACTORED LOADS
(OP)
As of late, many Engineers of Record (EOR) have been providing only UNFACTORED LOADS for the producers of Multi-rotational Bridge Bearings and are requiring the Manufacturer to Factor the loads for their design of these bearings. This seems contrary to AASHTO LRFD Specifications and other AASHTO documents that clearly state that the Bridge Designer (not the Bearing Producer) should determine the Factored Loads. It seems inappropriate for the EOR to put this onto the Bearing Producer who is not really qualified to determine the correct factors.
Does anyone have any comments on this???

You can try this site, they have some LRFD publications that might be useful:

Thank you.

The connection of the fixed bearing to the superstructure is designed for Extreme I or II, which requires several loads in addition to DL & LL.
