The confusion in relating UBC97 to ASD is due to the fact that the Rw values from UBC94 were reduced by approximately 1.4 to get new R values in UBC97. Thus, the net design load remains about the same but "E" now essentially already includes a load factor. This is the reason E is divided by 1.4 for ASD. Thus if you are designing by AISC-ASD, use E/1.4 based on UBC97 (and using R-values from UBC97).
