Abstract

Abstract

Taking a SJ2-18 deviation angle tower with 220 kV voltage level designed by a design company in Anhui as an example, the research on full-scale test of the tower was carried out to verify the safety of weather-resistant cold-formed steel applied to deviation angle towers. The SJ2-18 deviation angle tower made of weather-resistant cold-formed steel passed the 100% design load test under 8 working conditions. The shear failure of the connecting bolts between the SJ2-18 leg and the SJ2-18 foot occurred when the load reached 140%. The test results showed that the structure design of the SJ2-18 deviation angle tower was reasonable, with safe and reliable strength which could meet the requirements of DL/T 5154-2012. The research results could provide an experimental basis for the application of weather-resistant cold-formed steel deviation angle towers, and provide technical support for the promotion of weather-resistant cold-formed steel deviation angle towers.
