Other Code: Math Behind Extreme Wind Loading  by David C. Young, PE In the last IAEI News (March/April 2002), I shared with you the details of the new extreme wind loading requirements of the 2002 National Electrical Safety Code (NESC). For structures sixty feet tall and shorter, the extreme wind loading only applies to the structure. For structures taller than sixty feet, the extreme wind loading applies to the structure and all the supported facilities. To understand the impact of the 2002 revision, lets crank through an example calculation.
