Design and Test of Cold Formed Steel Membersby Adolfo Zavelani, Politecnico of Milano, Milan, Italy, Politecnico of Milano, Milan, Italy,
Abstract: Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used for these structures but other solutions were also successfully tested, such as tubular and aluminum sections. The actual trend is still towards open sections and bolted connections. Cold formed sections of various shapes have already proven to match the design needs, in full scale laboratory tests and in working transmission lines.
