Section 1609.1.1 refers to Chapter 6 of ASCE 7-05 for Wind load requirements. It lists alternative methods and wind speed values. Only the requirements for ASCE 7-05 are implemented. Also, three methods are given in ASCE 7-05 and among them, only Method 2 - Analytical Procedure, is implemented into the program.

The pertinent requirements for Wind loads are identical in ASCE 7-02 except for GC_pn coefficient, which is given by

Refer to the following section (IBC 2003) for further information regarding the IBC 2006/2009 wind load case.
