ASCE 7-02 Figure 6-10

ASCE 7-02 Figure 6-10

ASCE 7-02 Figure 6-10

(OP)
I'm pretty sure I've spotted an error in Figure 6-10 but I'm looking for some concurrance by you all out there in cyberland.

ASCE 7-02, Figure 6-10 is the Method 2 wind table for low rise buildings and is titled "External Pressure Coefficients, GCpf" on the first page of the Figure (out of two pages).  On the second page, the title is different - "External Pressure Coefficients, Cpf"  

Note the missing "G" in the title of the second page.

I think it should be GCpf like the first page and looking at ASCE 7-98, sure enough, it's titled with GCpf and the factors are the same.

I just want to make sure that the error was in 7-02 and not originally in 7-98.  7-95 also is like 7-98 so I'm pretty sure 7-02 is in error.

Also - is there an ASCE errata site out there for ASCE 7?

RE: ASCE 7-02 Figure 6-10

Correct, it's a typo.
Have not heard of an errata site for ASCE 7. There is, however a publication called "Guide to the use of the wind load provisions"  by Kishor C. Mehta and Dale Perry for ASCE 7-98 and 7-02. Available through ASCE website.

www.ASCE.org

RE: ASCE 7-02 Figure 6-10

I don't have 7-02 but in 7-98, page 25 the GCpf is defined as the EQUIVALENT external pressure coefficient times the gust factor for MWFRS.
  The combination of GCpf on page 32 is referenced as "external pressure coefficient from Fig  6-4", and this is the way it is referenced in the figures also.
  In other words, I think the External Pressure Coefficient means GCpf for low rise MWFRS, and therefore the second page title in 7-02 is wrong.
