Design and Construction of Guy-Supported Towers for Radio Telegraphy

Proceeding on the assumption that a guyed tower inclined bodily by the pressure of the wind should have the points of guy attachment remain in a straight line, methods are given for calculating the following quantities: guy tensions (for windward, leeward and perpendicular guys), horizontal and vertical forces acting on the top section of the tower, stresses in the middle section, stresses in the bottom section due to bending, design of flat-top and umbrella antennas, change in stresses due to temperature variation, and dimensions of foundations and anchorages. These methods are fully illustrated by the complete calculation of a 625-foot (190 meters) high hollow cylindrical guyed steel tower. Tables of all guy weights, tensions, and sags are given, together with the quantities which determine them.
