General characteristics of steel poles used to support transmission and distribution lines

This paper will provide a general overview of different characteristics of transmission poles and general design considerations included in the ASCE Standard ASCE/SEI 48-11 Design of Steel Transmission Pole Structures. Information related to pole geometry and typical single pole configurations is provided. Then, information about connection between sections and types of foundations typically used by transmission poles is provided. A section is dedicated to explain two of the most important elements, strength and deflection, that need to be considered in the design of transmission poles. Finally, two examples are given to illustrate the effect of limiting two variables, deflection and base diameter, in the design of transmission poles.
