Scope
1.1
This Standard applies to structural antennas, towers, antenna-supporting structures, and roof- and wall-mounted structures, including their components, such as guys and foundations. It covers the structural design, fabrication, and erection of new structures, and the modification of existing structures.
1.2
This Standard is not intended to apply to (a) attachment antennas and arrays, or assemblies of such antennas; or (b) towers that support attachment antennas, extending less than 15 m above grade, including the height of any structure on which they are mounted.
1.3
This Standard covers the requirements for most structural antennas, antenna towers, and antennastructures, but it is recognized that structures that are unusual with regard to their height or shape, or with regard to the shape and size of individual members, or that are located on sites having unusual topographical, geological, or climatic conditions may not be adequately covered. In such cases, appropriate engineering principles providing a level of reliability at least equivalent to that provided by this Standard should be applied.
1.4
This Standard does not contain mandatory requirements that take into account 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 should be prepared by an engineer qualified in the specific method and knowledgeable about the materials to be used, and should provide a level of safety and performance that is not less than that implicit in this Standard.
1.6
Responsibility for observing all applicable local, provincial, and federal regulations is not relieved by compliance with this Standard.
