Bill -

Thanks for the input.  I had not read the footnote so now it looks like the 
use of 1.3 is even more justified out to the 5km line in the book, unless I 
want to plot it out.  Also, I am aware of the steel frame connection 
penalties.  We've had them in similar fashion in the old Code since the 1994 

Thanks again.

<< Bruce-
 1. Regarding the Near Source factor, Footnote 1 to Tables 16-S and 16-T
 allows linear interpolation between the 2 km and the 5 km distance, so you
 shouldn't have a step function as you go across a street.  
 2. For the OMRF designs, remember to consider the loading conditions in
 Section 2211.4 No. 3.1  (Equations 3-7 and 3-8) for LRFD or 2213.6 No. 2 for
 ASD.  These provisions establish a pretty healthy penalty for OMRF
