Section 2.0 - Loads

ID #1145

Section 2.6.5: Addendum 2 defines Exposure Category C as "Sites located in Exposure B terrain that are located further than two miles but less than twenty times the height of the structure from an Exposure D terrain." That region is only possible for towers more than 528 feet tall. Did the authors mean "...less than two miles but more than twenty times the height..." That would make more sense and coordinate with the definition of Exposure D.

This provision is intended for tall structures where the 20 x the height of the structure was considered overly conservative when the structure is in an Exposure B terrain at least 2 miles from the shoreline. This is an exception to the distance specified by ASCE7 where Exposure D applies.
