FWIW, Congress is trying to use the FHWA to force all state DOTs into using metric units, as you probably all know. AASHTO is trying to take advantage of this effort by attempting to force a transition to LRFD for bridge design at the same time. Their primary argument in favor of our spending non-productive time learning the new code seems to be that it would be "cool" if we had a new design technique; one that's newer than any other country's.(?) At least they keep assuring us it generates the same results as the design techniques we use now. (Currently we use LFD for concrete and ASD for steel.) In this age of taxpayer demands for ever-smaller government staffs and ever-increasing workloads, at least some of us have little time to spend learning LRFD, especially since little design and analysis software exists for it yet. For one thing, we're too busy trying to deal with such things as designing metric bridge rehabs for structures built in English units, converting back and forth and back and forth again. But, hey, at least our roads will be more competitive in the international marketplace, eh?:-) Nigel ...
