ASCE/SEI 48-2019

Design of Steel Transmission Pole Structures

Prepared by the Design of Steel Transmission Pole Structures Standards Committee of the Structural Engineering Institute of ASCE

Design of Steel Transmission Pole Structures provides a uniform basis for the design, detailing, fabrication, testing, assembly, and erection of steel tubular structures for electrical transmission poles. These guidelines apply to cold-formed single- and multipole tubular steel structures that support overhead transmission lines. The design parameters are applicable to guyed and self-supporting structures using a variety of foundations, including concrete caissons, steel piling, and direct embedment. Standard ASCE/SEI 48-19 replaces the previous edition (ASCE/SEI 48-11). This standard includes a detailed commentary and appendixes with explanatory and supplementary information.

Standard ASCE/SEI 48-19 will be a primary reference for structural engineers and construction managers involved in designing and building electrical transmission lines, as well as engineers and others involved in the electric power transmission industry.
