Abstract :
The paper, after briefly considering previous work done in Great Britain, discusses the requirements of a reinforced-concrete transmission-line pole. Details are given of experimental poles, with an analysis of results of tests to destruction. A graphical method of design is developed and sufficient information is provided to enable future work to be undertaken on the bases established. An expression is obtained for the deflection of a pole under load, and it is shown that deflection cannot be taken as a criterion for proof-test purposes. Fabrication and erection methods are discussed, and the paper concludes with a survey of the advantages and disadvantages of the concrete pole, reference being made to a questionnaire issued to a number of users in this country.
