What are load cases A & B in Figure 6-18A-D in ASCE 7-05?  

RE: Open Structure Wind Design

They are simply two different load cases that must be included in your load combinations for W.  

A is typically the wind condition where the windward slope has positive pressure and B is the case where all surfaces experience negative, suction, pressures.
