wind load in icc - possible error?
icc (2003) section 1609.2 - definition for effective wind area is nearly the same as the definition in the asce-7-02 - section 6.2 except for the icc refers to the tables 1909.6.2.1(2) and 1609.6.2.1(3) where the asce-7-02 refers to figures 6-11 through 6-17. both refer to the product gcp. the asce-7-02 seems to apply this definition to method 2. i am assuming this is not applied to method 1 (simplified method)
the author of a study guide i believe is misinterpreting this definition. he is applying it to the cladding and components section of method 1 as insinuated by the definition in the icc. since gcp in both codes refer to asce 7-02 (figure 6-5 - method 2) i am assuming the definition in the icc also refers to method 2 (rigorous analysis)
the bottom line - do i compare the wind area width (minimum of 10% of least span or 40% height but not less then 3' or 4% of least span) to 1/3 the height of the building? refer to figures 1609.6.2.1 and figure 1609.6.2.1 (icc 2003) or figures 6-2 and 6-3 (asce 7-02)
