rohn solutions iunders ta ndingeia 2 2 2 revisiong topographic categories topographic categories are used to determine increases in wind loading for sites located on hills and other elevated locations other than buildings the shape and size topography of an elevated site determines the increase in wind load although many elevated sites have their own unique features the intent is to idealize these sites into one of the standard topography categories described below for structures supported on buildings it is only necessary to specify the height of the building and the surrounding exposure category wind loading in accordance with the standard this should not be confused with the elevation of the site as described below elevations of the site and the surrounding terrain may be used to determine height category 1 flat or rolling terrain with no abrupt changes in general topography no increase in wind loading is required for this category category 2 sites separated from a lower elevation by a gently sloping terrain escarpment wind loads at the crest not apply for structures located in the lower half of the sloping terrain or located beyond 8 times the escarpment s height from the crest category 3 sites located at the top or within the upper half of a hill wind loads at the top of a hill are 2.3 times the phone 309 697-4400 · fax 309 697-5612 · www.rohnnet.com · the industry standard 13
