I'd be real curious about which sorts of structures show the greatest
efficiencies and whether there's a correlation between the degree to which
lateral loading plays a part in the efficiencies. Was any comparison done
to determine where the efficiencies come in? (Column, girder, connection
economies? High rise vs small structures?) Are you implying simply lower
allowable design margins based on more analysis or is there something
inherently more reliable about LRFD that provides a better estimate of the
margin?
