Design of Steel Lighting System Support Pole Structures,

ASCE/SEI 72-21, provides design parameters applicable to self-supporting structures, with base plates for installation on a concrete pier foundation, or as direct embedded, backfilled poles with the base section being either steel or concrete.

Lighting system support structures have unique design and performance-related characteristics.

This standard provides recognized literature for the structural design, fabrication, installation, inspection, and maintenance of cold-formed single and multiple-section tubular steel lighting system support pole structures.

The standard is applicable to self-supporting poles with base plates supported on foundations with anchor rods, and to poles without a base plate supported on direct embedded, backfilled steel or concrete sections. This standard applies to round and symmetrical multisided cross section galvanized steel poles.

Minimum design criteria are specified, including combinations of loadings, strength requirements, deflection limitations, and fatigue strength considerations. Guidelines for fabrication, installation, inspection, and maintenance are also provided.

The design, fabrication, and installation provisions of this standard are intended for new structures.

Means and methods for construction are not within the scope of this standard.
