1.1 This Standard applies to the structural design, fabrication, and erection of new, and modification of existing
(a) structural antennas; (b) antenna towers; (c) antenna-supporting structures; and (d) structural components such as guys and foundations that form an integral part of the structure.
1.2 This Standard is not intended to apply to
(a) attachment antennas and arrays, or assemblies of such antennas; or (b) antenna-supporting structures for attachment antennas extending less than 15 m above grade.
1.3 This Standard is intended to cover the requirements for most structural antennas, antenna towers, and antenna-supporting structures, but it recognizes that structures which are unusual for their height or shape, or for the shape and size of individual members, or located on sites having unusual topographical, geological, or climatic conditions, may not be adequately covered.
1.4 This Standard does not have mandatory requirements for the consideration of the effects of earthquakes or the dynamic effects of wind.
1.5 A rational design based on theory, analysis, and engineering practice acceptable to the owner and regulatory authority may be used in lieu of the design procedures or materials described in this Standard. In such cases, the design shall be carried out by an engineer especially qualified in the specific method and knowledgeable about the materials to be used, and shall provide a level of safety and performance which is not less than that implicit in this Standard.
1.6 Compliance with this Standard does not relieve any person from the responsibility of observing local, provincial, and federal regulations pertaining to antennas, towers, and antenna- supporting structures.
