 My code (1998 CBC, first printing) says:": ... the load combiations of  
1612.2
 shall be used."  1612.2 load combinations are USD and do not contain a 1.4
 factor.  ie Eq 12-5 or 12-6.

 First errata to UBC97 changes the reference to 1612.2 to 1612.3, which means 
E/1.4 for drift calculations using ASD. It may not be the intention of the 
author, but there is also the Rho factor which got misinterpreted. You Loose 
some, you win some.
