توضیحات:
This
Standard provides the requirements for the structural design and
fabrication of new and the
modification of existing structural
antennas, antenna-supporting structures, mounts, structural
components,
guy assemblies, insulators and foundations.
This Standard is based
on limit states design. It is applicable mainly to steel structures but
may
also be applied to other materials, when required, so as to
provide an equivalent level of
reliability.
The appropriate
standards should be referenced for structures that support antennas but
that
are primarily intended for other applications, such as water
towers, electrical transmission line
structures, sign support
structures, buildings, bridges, etc. This Standard, however, does apply
to
the calculation of effective projected areas of appurtenances
(antennas, mounts, lines, etc.)
and to the serviceability limit
states appropriate for structures that support antennas
