Foundations for Transmission Line Towers and Tower Erection [PDF]
Transactions of the American Institute of Electrical Engineers, 1915 As tower anchors have been somewhat overlooked, causing in some instances much loss, these notes are written to call attention to the importance of properly designing them so that the maximum strength of tower may be obtained with the most economical outlay. The notes show: 1. A method of figuring the loads to be resisted by the anchors. 2.
