RE: Residential prescriptive MWFRS wind pressure

Title: Message
Eli,
 
I've found it very helpful that 2003 IBC actually includes Section 1609.6 for the simplified wind load method, which most residences will qualify for -- you don't have to pull out ASCE 7 (for now).  Use of this section is allowed by 1609.1.1, Exception 1.

Jim, I bet you can't find any code information on how to design a steel beam in the IBC either :)
 
Starting with 2003, the IBC now references ASCE 7-02 for all of the building load requirements.

List,
 
I can't find any mention in the IRC (2003) of what wind load to use for lateral force design.  Only tables for C&C are included.
 
Am I missing a footnote or something?  Are C&C loads intended to be used for MWFRS residential design?
 
Performing a more detailed IBC wind load calc including zones, etc, seems excessive where only a small portion of an otherwise prescriptive house requires engineering.
