ASCE 7 typo

[Subject Prev][Subject Next][Thread Prev][Thread Next]

List –

I’d like to try and confirm a typo that I think I found in the ASCE 7-02 wind design figures.

Figure 6-10 on page 55 shows the GCpf load cases for the “Method 2” wind design pressures.  Note that the “G” is part of the term.

Figure 6-10cont’d (on page 56) has a table of the corresponding numerical values – but the table heading says Cpf…with no G.  What happened to the G?  This must be a typo.  If I have to calculate the Gust Factor “G” by hand I’m not getting paid enough!
