There seems to be a general consensus that Rev G is more ?stringent? than Rev F. Under Rev F the purchaser is required to provide the fastest mile basic wind speed and an exposure category. Ice should be detailed, but it?s not a requirement. With Rev G you will be required to provide wind speed, classification of structure, topographic and exposure categories, ice, seismic, etc. or default values will be used. Does ?stringent? mean that Rev G is more inflexible in design requirements such as mandatory ice values or does ?stringent? mean that the structure, if designed under Rev G, would be stronger and fare better than one that was designed under Rev F if default values for both revisions were used? If the latter is correct, then would a Rev G Class 1, Exposure B Category tower with no ice be ?less stringent? than one designed under Rev F using default values?
