I've mentioned this before, but ASD goes a lot farther than building 
design. Most of the cranes in this country are designed using basic AISC 
ASD rules, as are supporting structures for many things. When you're 
designing for serviceability and such things as fatigue, LRFD doesn't cut 
it. There are also requirements for certain types of structures to remain 
elastic (or nearly so) during earthquakes or other catastrophes because 
they need to remain operational. Can't have a nuke plant crane become 
non-serviceable and drop a fuel bundle during an earthquake. My guess is 
that ASD is going to be around for a long time.
