Supplemental Explanation of Table
Table
Column 1 - shows design case used as the basis for the calculations
Column 2 - shows the different construction element for which the wind load was calculated
Column 3 - shows the calculated wind loads using the 2009 codes with local amendment of
120 mph.
Column 4 - shows the calculated wind loads using the 2012 codes with the current local
amendment of 120 mph.
Column 5 - shows the calculated wind loads using the 2012 codes with a local amendment
stating the wind speeds to be used for the three maps. This approach basically
does not allow interpolation on the wind maps since the higher wind line is used.
